Customer Ratings & Reviews

I found myself getting headaches regularly recently. Working from home these days and living under the stress of 2020 circumstances, I wanted to identify the source of my discomfort. A friend recommended I buy the uHoo Air Quality Monitor. The cute little plastic tower looks like a cross between a vase and a wifi router. There was very little to setup besides plugging it in, downloading the app, and following the instructions from my phone. The app displays 10 air quality readings including a "virus index." When you click on the "Insights" tab it gives you notifications such as "CO2 levels are high" and then suggests opening a window. I'm not sure air quality was the source of my headaches, but it is nice to be reminded to pay attention to your air quality and then get tips on how to improve it. My favorite tip said to increase indoor humidity by growing tropical plants with large leaves.

PROS: - The app makes setup quick and easy - Provides very detailed information - Monitor is quite small and blends in - Customizable alerts (if there is carbon monoxide for example) - Works with Google Assistant, Nest, and Amazon Alexa CONS: - Can't connect to a 5GHz network - Requires you to enable location services in phone to setup - Takes a couple days to complete calibration for CO2 (for me at least) -- SETUP -- Setting up the uHoo air quality monitor is (for the most part) quite quick and simple when using the app (which is required). uHoo does a good job of helping you with each step in the process, even switching your phone from your home network to connecting to the uHoo. My only complaint about the setup process is that you need to enter your time zone AND allow the uHoo to access you phone location to complete the setup process. uHoo claims this is to help ensure the calibration is as accurate as possible. Thankfully, you can revoke the app's location access in your phone after the air quality monitor has completed both the setup and calibration. -- FEATURES -- The uHoo air quality feature helps to track: - Virus index - Temperature - Humidity - Air pressure - CO2 - VOC - Particulate matter - Carbon monoxide - Nitrogen dioxide - Ozone uHoo not only provides real-time information on each item above, but you can customize your own alert settings to notify you if any/all items are above a safe quantity (especially helpful for carbon monoxide). It did take a couple days for the CO2 sensor to complete calibration for me (which is why it's so high in my screenshot for the first couple days). I don't use Amazon Alexa or Google Assistant (I have a "dumb" home), but you can pair up the uHoo air monitor, allowing you access information from your Amazon Alexa or Google Assistant if you have it (and don't want to use the uHoo app on your phone). -- BOTTOM LINE -- My wife and son both have asthma, so it's very helpful to have so much detailed information on the air everyone is breathing in. The uHoo air monitor allows us to make adjustments (turn on/off our humidifier, maybe the home air filters need to be changed early, windows should be left open longer/shorter, etc) to help keep everyone as healthy/happy as possible. I'm especially looking forward to the uHoo monitor to assist with winter air monitoring.

With the Covid pandemic still firmly in place, we are spending much more time in our homes than ever before. Scientists have warned us for a long time that indoor air quality can actually be worse than outdoor air, and especially now, we need to be aware of what we are breathing indoors. uHoo hopes to help with this issue. uHoo is an air quality sensor device no larger than a small flower vase, that sits in your home and when connected to wifi, will alert you via an app as to the overall air quality in your home. The device contains nine sensors to detect room temperature, humidity, dust, carbon dioxide, nitrogen dioxide, VOC chemicals, carbon monoxide, ozone, and air pressure. It also has an added “Virus index” which measures conditions in the room and lets you know how likely viruses may spread in the air based on conditions. Setup is almost easy, but the wifi connection is a bit back-and-forth. The device will work on 2.4 ghz wifi, as well as “mesh” 2.4/5 ghz systems, but will not work on dedicated 5 ghz systems; unfortunately it doesn’t spell this out for you until you get pretty far along and try to connect it to a 5 ghz system, and then makes you go back to do it all over again using another route. That could be done better. But once it’s connected, and you’ve downloaded the app and created an account, you will be able to see a list on one page of all of the sensor readings in the area the uHoo is located in. A couple of them need to calibrate for up to 48 hours to give their most accurate readings. Once you have had the system up and running over time, it will also provide you with graphs for each item so you can see how each individual sensor’s readings go up and down in a given space over time. The app has the main “devices” area which is your main readout screen, and also an, “insights” area which as of the time of this writing, shows nothing except a blank screen. The top of the app has an info button that once presses will take you to an area describing what each sensor reading is measuring, and you can swipe-left through each of them for a better understanding of what each compound is. If a reading is in the safe zone, it appears in green on the main page. Orange is medium and it will give you tips in the info area as to how to improve the air, and any measurement in red (bad) will instruct you as to what to do as you should take that as a potentially dangerous reading depending on the compound in question. uHoo claims this will work with IFTTT-enabled smart devices to help keep your air cleaner (such as enabled air purifiers, humidifiers, etc) but I wasn’t able to test this feature. It will also work with Alexa and Google assistant. Not having other scientific devices to double-check this, it’s hard to know if the readings are precise or not, but I did some simple tests. As an example, I turned off my fan and air purifier in the room uHoo is in, and the readings for dust and carbon dioxide did begin to go up, telling me to open a window to improve air flow, etc. Placing it near a lit fireplace, the amount of carbon monoxide did rise a bit as well, so the sensors do seem to be working. As someone who has lung issues, it’s nice to have something that gives me detailed views of what I’m breathing. The deduction of one star in my rating is simply because of the price, as well as the power cable being a bit short to me as I’d like to see something that can stretch further for more options in placement. Is it work the up to $400 retail price? For someone like myself, it very well may. It’s an investment, but a worthwhile one for anyone concerned about what they’re breathing in their home. Always of course, check for sales to possibly save some, though. So, it’s a gadget that has value and in my opinion, worth it.

To be honest, I wasn’t sure what to expect from a unique product like this. I knew I wanted it because I have family and friends that have asthma and airborne allergies, and I also care for a couple of indoor cats. My main concern was the amount of particulate matter in my home, but I was super surprised to understand the other 8 things that can be going on. First, the uHoo app and device setup was a breeze...on iOS. At first, I tried setting it up on my Android device, but had very little luck getting past the hand-off to wifi. Anyway, you’re going to have to set up an account on the uHoo app and add the uHoo itself. You’ll be able to add more than one uHoo, so if you choose down the road. If you were wondering, you’re gonna have to keep it plugged in full time. There are a few sensors inside that will need a few days to calibrate itself, so pick a good spot and leave it alone! It has 9 areas of monitoring; I won’t go through each one as you can read about that on your own and determine what’s most important to you. Again, I wasn’t expecting various levels of monitoring from this little device. But here’s the best part about uHoo and its app: if any of the 9 monitoring warning thresholds are met, the app will notify you immediately, no matter where you are, and suggest ways to mitigate the warning levels. In many cases, it will suggest you run an air purifier, run the A/C or open some windows for fresh air. I mean, how else would you easily know your CO2 and NO2 levels are climbing? What about a CO leak? And that, in itself, is worth the price of admission. The uHoo also has a 1-10 virus index, 1 being best and 10 being worst. It takes into account all 9 sensor readings and presents a virus index assessment, meaning how likely a virus is able to survive in your home and how likely an airborne virus is able to spread. During a time of virus crisis, this is another way of mitigating your COVID-19 risk. For us geeky types that are truly interested in the data, the app presents graphs of each sensor and its readings throughout a day. I honestly don’t care about the numbers, but more about the trending; for instance, why does my air pressure readings spike around 9AM-12PM and from 7PM-10PM for the past week? Turns out that during the statewide flex alert, the electrical company was putting my Nest Thermostat in Eco Mode, effectively turning it off between 12PM-8PM. It was only when my A/C was on, the air pressure was up in my home. I know, pretty geeky stuff. Finally for tech savvy, there’s a bit of smart home integration. It has Google Assistant and Alexa integration, which seems to be the trend nowadays for most new devices. But with IFTTT, you could potentially purchase a smart air purifier that would trigger on if the uHoo detected high PM2.5 levels. The uHoo’s price is in the upper range of its class and it can get a little costly if you need a 2nd or 3rd in your home. That being said, I wouldn’t mind picking up another for my home. I currently keep mine in the family room, where we mostly congregate throughout the day.

It's an interesting little device, not much to it on the outside - just a white cylinder with holes on top and the bottom and a USB power cable. On the inside however it holds an impressive sensor array - temperature, humidity, air pressure, Carbon Dioxide, VOC, Particulate Matter (2.5), Carbon Monoxide, Nitrogen Dioxide and Ozone! It's an impressive combination! If you are to look at the commercial HVAC products - CO2 sensor alone would cost 2/3 of this device. What does it do? Normally in my case - it just reports all green (in the middle of a Texas summer), however on a rainy or cool day - it clearly shows CO2 levels creeping up.. I did not think of it before I've got a way to actually monitor it. Now I can just turn on a ceiling fan if I see CO2 levels creep up in my master bedroom or open a window to air out the room. It's a very good investment for anyone who thinks of looking at the indoor air quality for whatever reason. Getting headaches? Asthma? Allergies? Start with the air you breathe, it's possible that solution to your problem has nothing to do with medications! Few negative points: - there is no way to get information of this device locally, like, let's say - MQTT server. Sure there is Google and Alexa integrations and IFTTT, but I do prefer local access. - No Apple Home Kit integration...

I want to say right up front, as an HVAC contractor, I think that every home needs one of these. Especially if you have natural gas or propane appliances in your home. This includes a furnace (split system or package), water heater, fireplace, wall mounted or freestanding gas heater stove, cooktop or oven. Kerosene heaters too. It could save your life. What it does: uHoo has 9 dedicated indoor air quality sensors: Temperature Humidity Carbon Dioxide (CO2) Total Volatile Organic Compounds (tVOC) Dust (PM2.5) Carbon Monoxide Ozone Nitrogen Dioxide Air Pressure It uses these to monitor the levels of each item in a room of your house. You can change locations but it will need time (a few days) to acclimate to each location. You can even use it outside but you will need to make sure it’s in a dry space where rain won’t reach it. From what I can tell it takes a sample every minute and plots it on a graph. You can view the graphs by the hour, day and month. In the month view it shows the minimum, maximum and average. You can set an alert in the app to warn you when a level gets too low or too high. Please see screen shots. I have professional test gear to test the Temperature, Humidity, Carbon Monoxide and air pressure (barometer) and they are dead on accurate. I’m not going to go into all the health effects of the nine items uHoo monitors. That would make this review way too long. The app gives a basic overview of each item. Looking at the temperature graph and the humidity graph you can see when your air conditioning is cycling on and off from the peaks and valleys. You can also look at a month graph and see if your system is keeping up. Say you have a refrigerant leak in your air conditioning system. You would see that the run times are longer over time and not reaching the set point as fast or eventually not at all. This is the same type of graphic info as refrigeration systems at super markets use which was invaluable to me when I used to be a commercial refrigeration tech High Carbon dioxide CO2 levels can cause you problems like sleepiness and headaches to name a couple. I discovered my CO2 levels were getting high at times. Cracking a window made a big difference and brought it down. It did have a very small effect on increasing the humidity. Cooking can run your CO2 levels up too. Carbon Monoxide has stayed at zero on my uHoo and my professional CO tester reads the same. This is the most important item it reads out and why I wrote what I did in my opening statement. Ozone and Nitrogen Dioxide can cause health problems and make existing ones, like asthma, worse. This tracks those. Pretty much everything uHoo tracks can cause some sort of negative health issue at varying levels for each. At high levels they can be deadly. Especially if you have asthma, COPD or other pulmany issues and even non pulmany issues. I highly recommend researching all the things that uHoo tracks beyond temperature and humidity and how they can affect you. Setup and App: uHoo doesn’t come with a manual. It just tells you to go download and install the app. The app will take you through setting it up on your smartphone and WiFi network. It will ask you to turn on location (GPS) during setup. You do not need to turn location on when you use the app after it’s been set up. Once set up it will need time to acclimate to its location and certain sensors will need time to auto calibrate. It tells in the app if they are calibrating. My uHoo didn’t work when I set it up. I tried several times by resetting and reinstalling it including uninstalling and reinstalling the app. I ended up talking to customer support and an engineer. Turned out my problem was my internet connection. I have satellite internet via Dish Network (Exede) and the long ping time in excess of 670ms was timing it out. Adjustments were made and it’s worked perfect since. They were outstanding with their customer support as this took some time to figure out. I would highly recommend this product and will recommend it to my HVAC customers too.

I am a member of Best Buy’s Technical Insider Network, TIN for short. Reviewers in this invitation-only program are provided products for the purpose of writing honest, unbiased reviews. This is a neat little device. I was not expecting much when I opened the box. The device is about the size of a soda can. There are slits in the devise for air flow. There are no fans. There are operational lights that are only lit during initial setup with your wi-fi network and the mobile app. You place this in a room, plug it in, and forget about it for a few weeks while it collects air quality metrics. The device itself may be the most boring piece of technology I own but, after two weeks of collecting metrics, it has got me thinking about the air quality in my basement. Normally, with most IoT devices I have owned, the device represents a “great promise” of some amazing “I need this in my life” feature. And then the accompanying app is either some marketing gimmick, after thought, or simply falls of making a good product great. Uhoo does not hide the fact that their product is a paperweight. The magic is in the sensors and the app. In my opinion, they did a great job with the app. There is room for improvement that I will go later. So, what does it do? The uHoo collects 9 air quality factors every minute: temperature, relative humidity, dust, carbon monoxide, nitrogen dioxide, VOCs, carbon dioxide, ozone, and air pressure. Current readings for all nine air quality factors can be viewed at any time from the app’s home screen. Each quality factor can be viewed individually by hour, day, or month as you scroll through the home screen. Touching the title of each quality factor puts the focus on that one quality factor; giving you access to every data point collected from today all the way back to the earliest data points. The graphs break down by Month, Day, and Minute. Moving your finger along the graph will give you the exact reading for any given data point. The app allows for the setting of alerts, adjustment of measurement thresholds, and will offer suggestions based on insights uncovered through the metrics. For example, at the bottom of the home page is a button labeled “Insights”. After two weeks, the insights offered two tips: Adjust my room temperature to make it more comfortable and adjust the room temperature or add a dehumidifier to reduce the chances of mold growth. I agree that I probably could have figured those two out on my own. However, the detector is measuring more than just temperature and humidity. You will find attached multiple charts for Carbon Dioxide with this review. I have a monthly chart, a few day charts in different orientations, and an hourly chart. Each give me similar, but slightly, different kinds of information. If you look at the charts, you will notice that the Carbon Dioxide seems to climb, then falls off sharply, and then steadily goes up again. A single graph over a day is not a pattern. But, if I keep seeing the same, or similar pattern over time, then I must ask myself what is happening in my basement to cause the Carbon Dioxide to fluctuate like it does. I was able to correlate the increase in CO2 to the frequency of showers. I have a boiler system. Showers force my furnace to kick on to maintain the water temperature for the shower. The CO2 rises slightly when around the same time furnace kicks on to heat the water. I will concede that a correlation is not causation. And I will need more closely track when showers are taken. Then, much harder, track when and for how long, the furnace runs. The key take-away is that it is getting me to think about my home in ways I had not considered before. So, who cares! Furnace runs, burns fuel, and sucks up the oxygen in the room to keep the flame running. Anyone who graduated first grade knows that fire needs oxygen. Well, I spend time in my basement for things other than watching my furnace run. The basement is sealed during cold days and days where the humidity is high. The furnace burns oxygen. I burn oxygen. I eventually feel groggy after spending a few hours in my basement. Part of the issue may be the lack of fresh oxygen entering the environment. I used to think the issue was fatigue. Or carbon monoxide. Well, now I have some metrics that may a different story. Metrics can be actionable. Perhaps I add some plants to the environment to keep up the oxygen. This reduces the competition between my furnace and my lungs for the limited oxygen supply. And I have a device that can give me some tangible metrics to support changes to my environment that would otherwise have gone unnoticed. I also know carbon monoxide is not my problem. A cheap detector can tell me the same thing. But you only know that a cheap detector is working when it goes off. Now I can see what is actually going on over time. What else am I going to find as I study the additional air quality factors and notice other correlations. As great as the app is, there is room for improvement that I hope uHoo chooses to implement. I would like to able to review multiple metrics simultaneously so I can identify other patterns. For example, and I am just making this up, is there a correlation between humidity and VOC levels? As is, I can only look at one graph at a time. There is no website, that I am aware of, that will allow to me further manipulate the data to tell a more complete story of the air quality in my room. Even an export feature to Excel would be helpful. I would also like to view metrics over a custom defined period of time. By default, the app will only allow a full month displayed as the largest unit of time. I can view all of August on September 4th but not the last two weeks of August including September 1 through 5 which are part of the final week of August. I am interested in seeing a year’s, or multi-years, worth of data. It is all about how metrics are gathered, used, and interpreted. When was the last time you bought a product that gave you the possibility of applying big data analytics to your own home? Normally, you have to pay someone lots of money to do it for you. I did not test this unit with the smart home apps like Alexa, Google Assist, IFTTT, Mediola, or Conrad Connect. The only device I have is Alexa. And the last thing I need is Amazon sending me marketing material for dehumidifiers and high oxygen producing basement shrubs that doubles as wi-fi hotspot for smart cat doors. The device itself is a boring, quiet, paperweight. Set it and forget it. The app is robust for a mobile app. It could be better if there were other ways to access and manipulate the data. I think Ohuu has a winner here. Thank you for reading my review.

This thing really works right away. If someone lights a cigarette in the house , it shows up on the monitor in minutes. Good quality also.

Recently and almost on schedule lately my area has been in the middle of terrible fires. I live in Northern Bay Area California and for the last few summers (this one being no exception) we have had multiple large scale fires. So much so that we currently have family here that had to evacuate their house. And despite the sky being shockingly beautiful around sunset with a red looking sun the air is terrible. So its great to have a device that not only lets us know what are air quality is, but gives recommendation on how to improve it, although opening a window in this situation isnt the best idea. The device itself has a very nice build quality and fits right in with most settings. Set up was fairly easy, but it does take awhile to calibrate. Now there might be people that think this device somehow can detect Covid and that just isnt the case. But with Covid being everywhere now it does cause most of us to be home a lot more often than normal, even more so with us due to the fires. Were in a no win situation currently. Cant go out and do things due to the virus, and risk lung and respiratory issues from the air. So having a way to detect what the air quality is in our house where you will be spending 95% of your time at is nice. Overall I would say this device is a piece of mind giver. Its one of those devices you hope you dont need like a fire alarm, but when you do have it it can be a life saver. Getting notifications of a change of, or an alert for some toxin, etc can literally save your life. So its definitely a worthwhile addition to the house. Hopefully these fires cease soon, but in the meantime its nice to know the air in the house is being monitored just in case it gets worse before it gets better.

The uHoo is a "smart" indoor air quality monitoring sensor. It covers 9 different things (temperature, humidity, air pressure, CO, CO2, Ozone, NO2, VOCs, and PM2.5). That last one is essentially just dust and about the only questionable measurement it gives. What makes it smart is that there's an app that goes along with it which can give you alerts for different types of scenarios using a combination of measurements of those nine quantities. In the context of COVID-19 and recent fires in the area, this kind of device can be useful but the ecosystem around turning that data into useful action is not really there. The uHoo package is pretty simple. The monitor, usb cable, and power adapter. You set up the device in one room, I'd recommend a family room or other main room in the house that gets decent usage, download the app and use it to configure the uHoo (pairing it to your wifi), and then you're off to the races checking out air quality and getting alerts. You get a colored (red, yellow, green) view of the quality of the 9 different monitors but you can also look at the actual numeric level that was measured. Some measurements aren't truly ready immediately, so plan on having this sit for a couple days before relying on all the monitors. I'm not sure what that means if you take it traveling - does it need another 2 days of warm up or is it just a first time thing? I don't have a good way to verify the numeric values reported by the uHoo. Qualitatively, I can verify a few monitors did change in response to environmental conditions. We've had fires in the area, about 3-4 hours away but waves of smoke which blanket the city. Enough that it's become a regular thing to come out in the morning to a car coated in a fine mist of ash. The uHoo definitely saw the change in CO and CO2 and NO2 emissions. On a day where the city was issuing ozone warnings, the uHoo did have it's ozone monitor go into the yellow at home. The PM2.5 has always been in the green - I suspeect it would work but the uHoo is designed as an indoor sensor and my own response, based on what I can see and smell is to close my windows when there's obviously poor air quality. So, while the uHoo does report things and seemingly it is responsive and likely accurate, on it's own, at the level that I'd notice the poor air quality myself, there's no beenfit over having yet another notification telling me something I either already know or would know from the radio, digital billboards, or other announcements in my normal day. So, it seems the big utility for this is in its integration wiht other services, IFTTT, Google assistant, and Alexa to name a few. If there was a recommended action that I could take with this in conjunction with my HVAC or some other device, perhaps an air purifier. However, aside from acting as another temperature sensor input to the HVAC, I don't really see this as a useful data source for my home automation. And my other devices already bundle environmental data from other sources in the area that I'm not sure I get much benefit from having the uHoo locally. I can see this being more usefull if there was a system in place to automatically close windows, purify air and take some action to combat bad air quality but at best, it seems it can serve as a warning that something is wrong when you're away from home for an extended period of time. The uHoo does a good job of monitoring and reports measurements in an easy to understand interface. But that's where things currently end. Without a way to make good use of this information, it's at the level of a home weather station - just duplicates information you likely already see when you glance at your phone or smart thermostat.

This indoor air quality monitor exceeded all my expectations. And at the end of my review period, it has become particularly essential. Measuring indoor air quality as it deteriorates with all the smoke from the fires here on the west coast. So, I'll start with that. As the outside air has been mostly on the hazardous scale since Labor Day with the monitor showing slowly increasing dust in the air and buildup of carbon dioxide most noticeably. This is because we are unwilling to exchange more air from the outside, so carbon dioxide is not getting diluted as much with fresh air. I think the dust reading is just from the finer particles that are getting in when doors are opened. We have made several more air cleaners by putting furnace filters on box fans to go along with some of our more fancier air filter systems. After we did that we watched as the uHoo showed lowering dust/fine particle levels in the air. This has helped us to quantify what is going on with the air that is getting inside from the wildfires and help us see how our attempts to keep the air quality as good as we can have been doing. So, now the main review. The Uhoo helps you see trends about things you can't readily observe. Setup was very easy and through the smartphone app, which you must use. Upon setup being completed, the app shows how long till the various sensors will be done with calibration. The longest takes 2 days, and that is the Carbon Dioxide sensor. The uHoo should be left in the same place for this initial 2-day period. So, I set it up in a large bedroom that has good airflow during the day and slightly less airflow at night when the door is closed. All the readings were good and well in the green except for the Carbon Dioxide readings which were in the red. The default settings are pretty good for the levels, and there are Green for Good, Yellow for Borderline, and Red for Concerning. You can set alerts for different levels to keep you updated. After two days and initial calibration was completed, I moved the sensor around the house every couple of days and the Carbon Dioxide levels were about the same throughout the house, but the highest in the large unfinished room in the basement where the furnace is. It was a bit higher there, and that room does not have any central air duct outlets in it, just the huge furnace stack and fan. We left the uHoo in that room for monitoring, since it had the worst air quality in the house. You can buy more units if you want multiple rooms monitored at once, but that will get very expensive very fast. The app shows data from all the sensors. You can see the trends by the current hour, by the current day, or the month. You can easily swipe to the left when seeing the current hour for instance, to see the full data chart form the previous hour, works the same with the day chart, and I assume with the month chart. This led me to airing out the house, and with box fans to pull in fresh night air upstairs and push out air downstairs in the mudroom exit, the carbon dioxide levels would drop well into the green after about 20 minutes. And then when we shut the house back up for overnight, they would slowly creep up back into the red, mid 1500s or even a bit higher. The uHoo helped me realize something I had completely overlooked about our big old house. It was built in 1960 and we have lived in it about 5 years now. What I didn't realize is that it does NOT have an air exchanger built into the Central Air system. I was so use to ones on timers or otherwise set and forget at my previous houses, that I didn't even think about it. Well, we have made the house a lot tighter as far as energy efficiency since we moved in, so we are keeping the same air longer, and carbon dioxide builds up from all the people and I learned from all the plants at night when photo synthesis is not happening. Since we have started airing out the house, complaints of headaches and random fatigue have gone down noticeably. You really need to keep on top of air quality when a lot of people are stuck in the house, either due to quarantine or the really bad outside air this September from the fires. The uHoo has helped tremendously with these issues and I wholeheartedly recommend this to give your family a sense of how things are trending with the Air quality in your home.

It is challenging to write a review for a product like this without having a laboratory to backup the data. However, the sensor seems to be accurate. Once connected to WiFi and the phone app, the data is easily accessible and sortable by hour, day, or month. From there, the app explains what each reading is, why it is important to measure, and how to improve that component of the air quality if it is bad ie open the windows, turn on air purifiers, get a humidifier or dehumidifier. This is extremely beneficial for someone like me who suffers from severe environmental allergies along with some asthma. The better the air quality, the easier it is for me to breathe. In the two weeks the sensor has been running, it has not proactively alerted me to any dangers, but I have air purifiers running nonstop. According to the sensor, they are working well. Via IFTTT, I can have the sensor control my purifiers based on need instead of running continuously. And, I have it linked to Alexa to be able to ask random questions like air quality, temperature, humidity. Overall, this device can be a valuable tool for someone who is extremely sensitive to air quality. I really love how detailed the app is when it comes to descriptions and solutions. While I have a science background, I think it is written well enough that anyone should be able to understand it. Hopefully it will help a lot of people out when they are not sure how to fix the air problems at home.

Bought it to monitor indoor air quality. Not fully satisfied. Leaves a lot to be desired. Has a few bugs that need to be fixed.
