Honeywell Home - T9 Smart Programmable Touch-Screen Wi-Fi Thermostat with Smart Room Sensor - White

I bought and installed this, and tried it out for 2 weeks, then ended up going with a competitor. I Really wanted this to work well, but it had 3 strikes with 2 that that I couldn't live with. The 1st problem is the vertical layout makes wall repair almost a sure thing when placing it in the same spot as the older more horizontal thermostats. The 2nd is there is no instant readout of your daily usage, you have to wait till the next day to get those numbers. The biggest problem, by far, was the room sensor reading was not displaying correctly on the thermostat. The thermostat operated properly, but when only utilizing the room sensor for operation, the thermostat would display different readings than it would show for room sensor. On the plus side, I did love the display and ease of use, As well as the room sensor requiring only 2 AA batteries.

I received the Honeywell T9 at no cost for an honest review so here it goes: Having previously owned 3 other Honeywell models, I was very pleased with the ease of installation of the T-9. Their instructions are some of the easiest to follow that I've seen in a thermostat. No longer do you really need to call your electrician, as this thermostat is really designed with the home user in mind from start to finish. With that said, I have installed other thermostats before so installing this one, especially having removed another Honeywell, took me just about 10-15 minutes. The most frustrating part was the app setup. So with this thermostat, Honeywell uses their "Honeywell Home" app, whereas I was previously using "Total Connect Comfort" app (incompatible with the T-9). I had to create a new account and pair it with the thermostat. Though I've set up previous Honeywell thermostats before, this one took me a good 25-30 mins just to get it to pair correctly. Once it did, it kept intermittently disconnecting. I have a Samsung Galaxy S9+ and I was following instructions as given on the thermostat screen. After 20 mins or so, I decided to call Honeywell's Tech Support, and they suggested that in addition to Airplane mode, I disable cellular data since some Android phones tend to have connectivity issues. Well, this solved the problem so I was happy with that. The final step of the thermostat registering took like 3-4 minutes, so if you think the thermostat is frozen, it's not, it just takes a bit. This is the reason I took off 1 star. If they can update their thermostat instructions or their support manual, you can avoid this headache since this is designed to work with all smart phones. One really nice feature, was when connecting to your home's wifi, the thermostat provides you with an on-screen keyboard. I found this to be very helpful as I haven't seen it before on a thermostat. The screen is a bit small so I do wish it was bigger, but for what it does, it serves its purpose. As far as new features on this one, it does come with a separate temperature sensor that you can place anywhere in the house, and run the thermostat based off that room's temperature. It also has adaptive technology that enables the thermostat to intelligently learn how to best warm up or cool the home down using certain ventilation patterns (the way I understood it). It does work with many different smart home devices including alexa, google assistant, cortana, samsung smartthings, apple homekit and the list keeps growing. Once all was said and installed, the thermostat is very simple to use, very intuitive, and sleek-looking. I do recommend it, and if you run into any kind of trouble with setup, Honeywell and Resideo will be glad to help you.

When setting up you can set the temperature for different temperature for wake and away and sleep and home and add sensors to other rooms

My previous programmable thermostat was a nightmare to use. The readout was confusing, programming it was agitating, it seemed to only work when it wanted to and it needed batteries to function which was the frosting of annoyance. I was in need of a new thermostat that would afford me the luxury of programming it to what I desired. The Honeywell Home T9 Thermostat has exceeded my expectations while introducing me to features that I didn’t know that I wanted. Setting up the T9 is relatively easy for as long as you are aware of what your current wire setup is for your existing thermostat. Having an existing C-wire will definitely expedite the setup. The T9 does come with a C-wire adaptor but the installation will require a couple of extra steps but there’s no reason to feel overwhelmed because Honeywell has a fantastic YouTube video that will walk you through the installation. Once installed, setting up the T9 was as easy as using a smartphone. The touch screen display on the thermostat is CLEAR and RESPONSIVE. The touchscreen didn’t ‘misread’ what I was pressing, and the function readout is sharp. The T9 is accurate with your interactions. What’s exciting about the T9 is that it comes with a room sensor. This sensor allows you to focus on a specific room when it comes to the temp. For example; you might have the thermostat in a hallway but that hallway temp is a far different temp from your bedroom or entertainment room which means you have to compensate temp degrees. By putting that T9 sensor in the other room, you can now tell the thermostat to keep that room at the desired temperature that you want without having the thermostat taking precedent over the desired temp that you want in the said room. The T9 allows you to add several more sensors to other rooms of your home if you want to. The sensor will also detect if there are additional people in the room or home and adjust the temperature flow to what it senses. It’s pretty impressive. The T9 offers me the ability to set the temperature for specific times of the day. You might yearn for an average temp while you sleep but you want to wake up to a warmer or cooler temp, you can program the T9 to activate at a different temperature. The options of programming the T9 are plentiful and I’m sure that I haven’t discovered them all at this point. There’s even a password option in case you don’t want anyone else adjusting the temperature that you have set. And then there’s the luxury of remote options with the T9. We’ve all been in those moments where we are suddenly too hot or cold but don’t want to make the effort to get up and change the thermostat temp. I can either use the Honeywell Home app to change the temperature without getting up or I can order Google Assistant to change the temperature while keeping my laziness intact. The T9 is also compatible with Alexa. I can change the home temperature via the Home app when I am not at home. And yes, you can even turn off the thermostat from the app. I think this will afford a lot of people the peace of mind when the weather suddenly becomes unexpected. I’m anxious to see how much money I will be saving here on out because of the temperature balance feature of the T9. I honestly believe that the Honeywell Home T9 is a needed investment in comfort and savings.

Very easy to use! I added six more room sensors. Like how the room sensors all work together to get the perfect temperature throughout the whole house.

I'm 100% satisfied with the product super easy to install and to use it as well.

Honeywell T9 I have been looking at these types of thermostats for a long time. The one thing that has held me back is the need for a C-wire. As my current thermostat connection only uses a green (G), yellow (Y), red (R) and white (W) wire, I was fairly confident there was no C-wire connection. Running a new wire from my furnace control panel to my current thermostat in the second floor hallway was not a task I wanted to take on. This Honeywell T9 thermostat was advertised as no C-wire needed. I am happy to say THIS IS TRUE. Unboxing: The components come packaged well. You receive the thermostat and back-plate, room sensor with a device to attach it to the wall, and the C-wire conversion kit. There are instructions for installing the thermostat, room sensor and the C-wire conversion. They are written very clearly and easy to follow. Installing: You must turn off the power to your furnace and air conditioner while wiring the thermostat. As I was not 100% sure if I did in fact have a C-wire and it was not being used, the first thing I did was remove my current thermostat and check the wiring. A ray of hope came upon me as the instructions say to look for an unused wire and I had an unused blue (B) wire. So I wanted to run a test and connected the G, R, Y, W and B wires per the instructions. The thermostat did not turn on to the welcome screen. I checked the wiring and found a blue wire connected to the Y on my furnace. Tracing the wires back I found the installer had changed from a 5 wire to a 4 wire and connected the Y to the B. I then installed the C-wire conversion kit. This was easy and took maybe 10 minutes. It is very nice having the wire insulation cut on the conversion kit so you do not need a wire stripper. Turn it on and still no power to the thermostat. Unfortunately I did not read the instructions clearly enough I guess. I still had the original connections to the thermostat back-plate. After using the C-wire conversion kit, I needed to remove the B wire – change the connection of the G to the C connection – change the Y to the K connection. After completing this simple change, I turn the power back on the welcome screen is displayed. SUCCESS!!! Install the Honeywell Home app on my Android phone and complete the installation. I connected the provided room sensor and placed this in my main floor living room. Using: You have two options for using the smart thermostat: schedule and geofencing. I was most interested in the geofencing. For this option all you do is set three things: 1) the heat or cool temperature when you are home; 2) the sleep time and heat/cool temperature; and, 3) the away heat and cool temperature. For each of these you also set the room priority and fan setting. This works really well! There is one thing to be aware of that impacts me and likely very few people. The radius for the geofencing is 500m. One of us works less than 500m from the house. So it does not determine we are away when at work. This is the minimum setting. I wish I could set it to 300m. It would then work perfectly! Using a schedule is similar to what you may be used to. The one difference is you can also set specific days. One thing I did not like about my old thermostat was there was a weekday and weekend schedule. Well Friday and Saturday night are the same for me but Friday is on a weekday schedule and Saturday on a weekend schedule. Similar issue for Sunday night as this is on a weekend schedule and is the same as Monday for me. The scheduling is very flexible and you can set each day, or group days, any way you desire. Conclusion: I give this Honeywell T9 thermostat 5 stars. It can be installed with on C-wire. You have flexible geofencing or scheduling options. It includes a room sensor for another location. The Honeywell Home app is intuitive and easy to use so you can control it from anywhere using your phone.

This is my third Honeywell Wi-Fi capable thermostat, dating back several years. All have performed extremely well and are well designed. The T9 is a brilliant evolution of the Honeywell series. The drop-down menus are well laid out and understandable, an impressive improvement in the T9 system. Configuring personal preferences, system priorities, scheduling, device sensors, Wi-Fi, and beyond are easily accessible and intuitive. You can even see the future forecast for your area in the menu. Kudos Honeywell. Installation and setup from basics to Wi-Fi worked flawlessly, simple and smooth. Like that. The new T9 model changes the shape of Honeywell Smart Thermostats in more ways than one, first the shape has a new face lift. Rather than being a horizontal unit the T9 is vertically shaped, which makes sense when using the touch screen interface and scrolling through menus. Like the aesthetics, looks nice on the wall. Love the new sensors and the ability to mange your whole home from sensors throughout the home. The sensor system can detect which rooms are being used and throughout the day will adjust the climate control to operate more efficiently. Like the ability to select a priority room for climate management and have the temp and humidity read out on the thermostat screen. Myriad of ways to control and monitor the system from the phone/tablet app or your PC as well as integrating with either Alexa, Google Home, Cortana, and more. The T9 uses Geofencing, which in a nutshell means it knows when you are coming and going by monitoring your phone and can adjust your system automatically. Additional features that stand out: - Does not require a C-Wire. - Includes Wi-Fi 5 GHz. - Indoor humidity sensing. - Honeywell usage reports. The T9 is by far the best designed and engineered thermostat that I have ever used, Honeywell hit a home-run with the T9.
