    Arguably the best thermostat available today

    Posted

    Ecobee has built on previous smart thermostat ideas with yet another killer feature: Onboard Alexa. For those that have your thermostat somewhere that is occupied/centralized in your house, this puts answers to questions, automation adjustments (such as temperature changes), and other Alexa functionality centrally in your house. Add this to the other awesome Ecobee4 features that carry over from the Ecobee3 such as room sensors, and you have a very solid product that really does a great job becoming a vital part of your daily routine. My previous top consideration, the Nest, was cool but had one major downside: If you spent too much time away from the thermostat, it would switch to "Away" and stop conditioning your house. Nest realized this shortcoming and released $100 combo smoke detectors and presence sensors. While I appreciate their thought, $100 per additional sensor is just not realistic for your typical consumer. Along came Ecobee. In the package you get the Thermostat and a second motion+temperature sensor, and can add more sensors than you'd ever need by buying additional packs. They are tiny (less than 2" x 2") and can be put just about anywhere. I have mine on the wall with regular push pins. Ecobee says you should get years of life out of each battery (worlds better than the 4 or 5 months I get from some of my other smart home accessories), and the range is acceptable but not fantastic. Installation was easy. I have an older house (late 70s construction) so I only had 4 wires. The Ecobee requires 5 wires, but comes with an adapter for houses with only 4. Side comparison: the Nest does not require 5 wires, but does recommend it. It can theoretically run off of 4 wires, but simply charges an onboard battery any time the air handler is running. If the battery starts getting low, it will actually run your air handler more than needed to recharge itself! I much prefer Ecobees honest approach to an adapter than Nest’s unnecessary additional runtime. Air handlers use about 500w of electricity simply running the fan! Not very green, Nest! The primary thermostat is easy to use, though to be honest I almost never touch it. The interface is mostly intuitive and easy to navigate. I wish there was a little more customization available for what information shows in idle mode (it changes modes when you approach the thermostat), but right now it displays the current calculated temperature (based on remote sensors that detect motion and the thermostat) as well as the outside weather conditions. Another enjoyable feature: Home IQ. Having an older home, I’m always curious to know how my home’s efficiency compares to that of houses around me. Ecobee’s Home IQ feature provides you insight into how your house compares to similar houses in your area. In addition, it tallies total daily runtime, presence sensor activity and temperature history, and a few other things. If their built-in analytics aren’t enough, you can download the raw data via .csv. The App works well, and mirrors the interface you are provided on the front of the thermostat. I do not have any Apple products, but the HomeKit/Siri integration is convenient for those in the Apple ecosystem. With how rarely I touch my thermostat, I don’t mind breaking my phone out or walking to the unit. Overall, I think I made the right choice. Here’s a TL:DR – Pros: -Integrated Alexa means convenience for your household -Saves money quickly over a non-scheduled thermostat -Keeps your house comfortable even if you don’t frequent the room containing the thermostat -Provides easy access via an app, web portal, or Siri -Gives you insight into your energy use and system cycle times via their Home IQ portal -Warns you of dangerous or unexpected temperatures inside your house -Active development by Ecobee means constant new features added to the software of the device. Cons: -Sensors are still a little expensive (I’d love to see a $20 price point) and can have a limited range -You may need to do a little additional install work if your home has less than 5 wires running to the thermostat

    Smartest Thermostat - BEST PRICE!

    Just bought a new home and I installed this! I love this! I have a basement floor, a main floor, and upstairs floor. We have two Heaters and two AC units. One Heater and AC for the basement and main floor and one Heater and AC for the Upper floor. I put 3 remote sensors in the rooms upstairs. And 3 remote sensors for main floor thermostate for kitchen and two in the basement. The thermostats also act as sensors with motion. I hooked this up with Apple Siri and I love this! I now have Alexa to help around the home also. I love how I can shop on Amazon Prime with Alex through my thermostat! Previously I had to use my Amazon Fire to use Alexa to shop with discounts with her. Now I love using my thermostats! Oh and did I mention I am saving money on my utility bills? My thermostats are so smart and know when to not come one, I am using my system's less than before and loving my constant temperatures! You need to buy this! I know that some people like that Nest because its flashy, but this does all Nest does and even more!!!!! For the same price!!!!!

    Another outstanding product from ecobee!

    Posted

    I am very, very happy with my ecobee4! It functions just like the ecobee3 does, but with some very nice and welcomed extras. • Amazon Alexa: She works! The far-field voice recognition works great. There are the occasional instances where she might not hear you, but I have the same issues with my Dot. I use Alexa pretty frequently on my ecobee4 while I fold laundry in the dining room (which is where the thermostat is) to play music or listen to my flash briefing. I also use my ecobee4 to control some of my smart home accessories like my smart plugs. • The speaker: The speaker actually sounds pretty decent and is loud enough to fill the room with some good quality sound...especially considering that this is coming from a thermostat. Pros: It works great, is fun to use, and saves on energy costs! I love the fact that there's a speaker in this and I use it while at home and entertaining. Sensors, sensors, sensors! I have sensors all over my house and use them to help get the most accurate average temperature reading of my house. I love the fact that they can detect if a room is unoccupied and therefor will focus on making sure the rooms that are occupied are at the desired temperature. The sensors can also be used as a motion detector with HomeKit and can be automated to interact with other smart devices around the home. I have the one in my bedroom programmed to turn on the lights after sunset when motion is detected in the room. Cons: As of right now, there is no Alexa ESP feature, so if you have multiple Alexa devices within range of each other, they'll all go off at the same time. However, I'm sure that'll be addressed and fixed at some point in the near future. Overall it's a fantastic product. If you want to upgrade your thermostat, I highly recommend this.

    It has its pros and cons

    I've been a Nest user for years, their product is simple to use and is very intuitive. But I opted for the Ecobee for my apartment because it comes with the room sensor (very helpful considering the thermostat is not located in a central location). However, the platform is complicated to use, Alexa always loses connection with the voice servers, and the Ecobee does NOT offer a fully customizable schedule like the Nest does. However, where the Ecobee shines is in its configuration settings. The Nest has a pre-defined algorithm for how to run your HVAC system (cannot adjust temperature thresholds, hold over times, etc), the Ecobee gives the user excellent control over the specifics of how you want your air to run (I adjusted mine from the factory default 0.5* threshold to 2* to keep my air off more than on). Plus, the room sensor allows you to set a temperature for a specific location (very helpful at night when keeping the bedroom cool is more important than the rest of the apartment). The Ecobee would be far better suited on a Zoned HVAC system, but even on non-zoned unit like mine, the room sensor still allows me to focus my temperature control over specific rooms to an extent.

    The ecobee4 was a great investment! I was torn between the ecobee4 and the Nest, as I use Nest's cameras, and would have liked to integrate the thermostat into the same ecosystem. However, being an Apple fan, I intend to dabble into Apple Home (Kit) much more once the HomePod is released, and the ecobee4 will work with it, as opposed to the Nest. I also like the remote temp sensors, as they have aided in our HVAC system working much better to correctly and evenly distribute the correct temp air throughout our home.

    Best smart thermostat - better than the bird house

    I purchased the other smart thermostat (that a bird would use for it's home) for my new home and hated it. It REFUSED to hold the temperature I set and the upstairs (2 story home) was always hot and uncomfortable. 2 months later I ripped it out and installed the...

    Replace Nest with Ecobee

    We are very happy with our ecobee4! It functions just like the Nest but better with more options such as Alexa, sensor for each room, includes two but I purchased 4 more. The sensors really work. We use the follow me feature and every room that is occupied is the temp we set. Pros: It works, it is fun, and saves on energy costs! Another pro is the sensors! I have sensors all over my house and use them to help get the most accurate average temperature reading of my house. I love the fact that they can detect if a room is unoccupied and therefor will focus on making sure the rooms that are occupied are at the desired temperature. The sensors can also be used as a motion detector. Amazing!!! Cons: the Nests app is more responsive and with little to no delay. The Ecobee app is delayed about 30 sec or more. I’m hoping they can fix that with future updates. Overall it's a fantastic product. If you want to upgrade your thermostat from Basic thermostat or even Nest like we did. I highly recommend this.
