ecobee SmartThermostat with Voice Control - Programmable Wifi Thermostat - Works with Siri, Alexa, Google Assistant - Smart Thermostat for Home

This product is everything they say and more. I love how it senses what room you are in (for any rooms other than the one the thermostat is in you would need the sensors, you get one with the thermostat but it helps if you can have one in each room) and it will focus on that room and keeping it at your set comfort level. It has Alexa built in which is wonderful. You can control everything with voice but to get all you can out of that, install the Ecobee app on your mobile device. This thermostat can not only detect which room you are in, but also if you leave the house and will enter AWAY mode and keep it at the temperature you set for when you aren't home. It automatically re-enters HOME mode when you get home. Once you get your comfort settings input into the device, you never have to do anything again. It will automatically change to your Settings (defaults are HOME, AWAY, and SLEEP but you can ceate other categories such as VACATION or whatever you need or want) and you never have to ever intervene. But if you desire, you can temporarily if needed (say you come in freezing and want to heat up fast) change the temperature of comfort settings by voice command. You can have it set ahead of time to keep the new temporary setting for a certain amount of time or until the next setting was scheduled to take over. You get to set what times to start and end SLEEP mode. The face is not flashy but has everything you need and more right up front. You have on the screen temp, humidity, Weather forecast, Menu, Settings for the Thermostat, Enable/Disable microphone so you turn off the microphone that lets you talk to the Alexa add-on and thus if you have another Alexa close they won't both vie for your attention.Let me tell you something. Installation is a breeze. If you know anything about working with HVAC or just electronics you should be able to do this totally on your own. If you don't know jack about any of it, have no fear. Their customer support has got to receive 5 of 5 stars. The technician that helped me took me from checking to see if it was compatible with my system ( I have a very old system. I have a gas furnace for just the heat and a heat pump system for A/C and it ends up that with the power strip they provided with this thermostat had to be installed to make it compatible) to completion and even went so far as to run tests with me to ensure it was working perfectly. He was on the phone with me for 2 hours and I had to send him a lot of photos by text so he could see what he was working with , but once he knew, we flew through the rest of the installation. I have had it about 6 weeks and it is everything they say and more. I do recommend getting a Room Sensor for every room. (Get the ones like the one that comes with it as it is more "Intelligent" than any others.) This way the Ecobee can maintain the comfort level for whatever room you are in. Buy it, you will love it!

In my opinion this is a great thermostat. I chose the EcoBee because of the Smart Sensors. My house has a bunch of rooms with a central thermostat. As a result, the temperature between rooms would vary greatly. The sensors seemed like a solution to a problem that has bugged me for years.The thermostat uses the average of the temperatures reported by the sensors to determine when to cool or heat. Once the sensors were placed around the house, it took about a day for all of the rooms to get cooled down and settle into a stable climate through the whole house. Before the EcoBee there was as much as a 7-9 degree difference between the coolest rooms and the warmest rooms in my home. Now, there is a difference of only a couple of degrees between all of the rooms, as one would expect due to the averaging being used.When a sensor detects someone in a room, that sensor gets more weight in the temperature average while unoccupied rooms get less weight on the average. This means that cooling priority is given to occupied rooms.You can setup multiple "comfort settings" (e.g. Sleep, Home, Away) which define a set of desired heating and cooling temperatures, then create a schedule for when each comfort setting is used. You can also specify which sensors are active in each comfort setting.The iOS mobile app is easy to use and intuitive. You can control the thermostat while away from home in the app. The EcoBee supports GeoFencing so that you can have the termostat turn on when you enter a fence that you can define.You also can control the thermostat using HomeKit. The thermostat can be used in Scenes and Automations. With an 4th Gen+ Apple TV, an iPad, or Homepod you can use HomeKit to control the system while away.The thermostat needs a stable 2.4 Ghz wi-fi connection. If you have spotty wi-fi ensure that your thermostat location has good 2.4 Ghz signal. I have excellent wi-fi coverage in my home and the EcoBee has been rock solid with no drop outs or disconnects.The thermostat has features like minimum fan run time, manual adjustment and hold.Install is easy using the included instructions. Included in the box are labels to tag your thermostat wiresso you know what each one is for when you start connecting the EcoBee. There are some nuances to moving from an old thermostat to a modern thermostat (wires that you can abandon, jumpers that you don't need with new thermostats, etc) so I cannot emphasize enough how important it is to read and follow the included instructions.The sensor pairing process is easy. It does take some time for the sensor to pair sometimes, just be patient.Bottom line, my wife has said that she feels a difference and thinks that the whole house is more comfortable. She notices a difference in rooms that used to be warm or stuffy. The room sensors are the real winner with the EcoBee in my opinion. They make a huge difference. Highly recommend this thermostat.
