    Replaced Honeywell Lyric

    The house I bought came with a Honeywell Lyric and was good for about a year and a half. Then it seemed to have trouble staying connected with Alexa as well as other wifi connection problems. Finally got tired of it and looked at the favorable reviews of this thermostat and got it. We already have an Alexa show and couple of dots so didn't need the Ecobee model with built in Alexa. Installation was very easy and set up was a breeze. It was easy to connect to Alexa. This has all the eco- friendly and learning features that are in other smart thermostats although so far the weather here has been mild so I haven't had to interact with it much. So far so good.

    The Best Smart Thermostat

    I finally took the plunge and purchased this fabulous Smart Thermostat. It was sure easy to install and has worked perfectly controlling the temperature I prescribed in the set up. I love that it comes alive when you walk up to it, and the weather is easily available. Love this thermostat!

    Simple Installation

    I initially purchased the ecobee3 lite since it comes with the without C wire adapter, however during installation I found the C wire was actually disconnected and used it without the adapter. Installation was simple, and configuration was easy via the touch screen and directions on screen. It's be working without issue, and I also have setup the app on my Note 8 and it works great. I would purchase again.

    Good value Smart Thermostat

    The thermostat was fairly easy to install, both on my home heating/AC system and home network. The instructions provided were excellent. I used the PEK unit and had an issue with the AC compressor turning on with the fan. Ecobee's customer service, via their online chat, was excellent in solving the issue, which was caused by a wire to the AC compressor that needed to bypass the PEK unit. A great feature is the ability to set both the Heat and AC settings automatically rather than 'heat' or 'cool' only settings. My HVAC system has the ability to continuously run the fan at very low speeds but the Ecobee 3 does not have that functionality. It would be a nice improvement if this was offered.

    Excellent thermostat

    I did a lot of research and I was going to get a Nest, but the HVAC company that we have been working with recommended Ecobee. Before getting any smart thermostat, please check your furnace for a C wire. My thermostat setup had the humidistat right below it. The wall plate the came with the Ecobee Smart Thermostat was big enough to cover the thermostat and humidistat holes. The HVAC company installed it for me. If you are not familiar with installing thermostats, please have an HVAC company install it. After installation, I was ablE to program it through the app. There is a sensor built into the thermostat and it comes with an extra external sensor, which I put in my office. I am able to see what the temperatures are in each room. After a good furnace cleaning and thermostat installation, My HVAC is working better and I have better control over my heating and cooling. With Alexa built in, I moved my Echo Dot into another room. The speakers on the thermostat are awesome for a small device. I used some wall paint to touch up where the old thermostat was. I plan on painting the walls next summer.

    No. ecobee3 lite works with 2.4GHz. For dual-band, please check out ecobee Smart Thermostat Premium or ecobee Smart Thermostat Enhanced.

  • I have a two level house with two thermostats. If I purchase two of these units, will they be connected to one control in the app, or will they show as two different units. In addition if sensors are added, can I track the temp one all devices?

    Hello - They will be two units, but controlled in the same app interface, you could just use 1st floor and 2nd floor or whatever you wanted to call them. The sensors are tied to a unit so if you had a sensor on the 1st floor you would tie it to that unit.

  • Since ecobee3 lite now supports room sensors, what is missing from ecobee3 that you'd get with the full ecobee? What's the difference between the two?

    4 has a full blown Alexa module built into the unit. That’s the only thing I can see as a differentiatior between the two

    Answered by SnowBall
  • Does the ecobee3 lite thermostat come with a Power Extender Kit (PEK) included in the box?

    Yes, it does.
