Excellent Thermostat!
Absolutely love this thermostat. Simple yet saves you money. Love being able to use the app to control it and see my power usage. After about a week you can setup a schedule. Unlike the models where you have to set it up at the unit, no in this case. You use the app and it’s very simple. LED display is bright and always on. Easy to read from across the room. I use the app mostly. Installation took me about 10 minutes. Very easy and straightforward. I have a gas forced air furnace and AC unit outside. It controls them easily and without a C wire. I’ve installed the app in 4 phones and they have zero issues controlling the unit. The mounting plate has a built in level so mounting it level is a breeze. Hooked it up to my Alexa show and it works perfectly with it. Another thing I like is it shows the humidity level of the inside of your home. Nice feature to have. All and all I am very happy with the thermostat and its features. As winter approaches I can setup a schedule far easier than standing at a unit punching in times and days. The app makes this very streamlined. It also looks very nice on the wall.

Easy to use and works great!
This was purchased for a church building where areas are unoccupied at various times. This first purchase was a trial. The heating system is hot water with a central boiler serving several zones.We found this thermostat much easier to install and program than a previous brand we had we had tried to use. It connected easily with our existing Wi-Fi. For our system (heat only) it required a “C” wire but fortunately the existing wiring contained a wire we could repurpose. We haven’t used the early start feature yet we’ve just estimated the time to achieve the set temperature and programmed the system to come on soon enough to achieve it. A conversation we had with the the help line informed us that the thermostat will learn the time needed to achieve the correct temperature.The one call to the help line was very useful. The wait to be connected was fairly long, 15 minutes or so, but the gentleman was very knowledgeable and able to answer all the questions we asked. We have also emailed a question and received an answer but the response is slow.We’re pleased with the appearance of the unit it looks very solid and it’s not obtrusive and it is also easy to read. We also like the fact it can be locked to prevent unauthorized adjustment.It has been convenient and easy to install the app on multiple phones and nice to be able to check and adjust programs remotely. It is also nice that it connects to some weather information and displays the outside temperature.It’s great to have the room at a comfortable temperature when you expect it to be.We will also connect the a/c system to it later which now runs on a separate device.We have been pleased with the unit and have ordered two more for other areas.

Great Thermostat that does what it says.
I am no genius, but this thermostat was a quick and easy task to install. It has photo instructions and they are step by step. If you pause very long in the process, a video of more instructions for that step starts playing and completely shows how to do that part of the installation. It works great and is easy to use. WIFI connectivity is excellent. I would recommend this product if you are looking for a user friendly thermostat that is smart.

An abomination when it loses connectivity
The Sensi Lite could be a simple little device, to fit the niche for those that don’t need all the programming options of more expensive units, but that’s not the case. We purchased this for our 2nd home. Our primary home has a more advanced unit from a better known smart thermostat vendor. It took a bit to get WiFi to connect on the Sensi Lite, but eventually it happened. All seemed well.However, this rural area tends to lose power a couple times a year. So, the batteries will die. When the batteries are replaced, the Lite doesn’t seem to want to reconnect. The app appears to have an option to Reconnect, but it NEVER works. We always end up having to remove and add the device back.As others have stated, the problem is when you go to setup on the thermostat (by holding the one tiny magical touch area on the unit for four seconds), the app will seem to be connected, but it doesn’t trigger the goofy scanning LED sequence on the Sensi Lite unit. The thermostat will then drop out of Setup. No errors, no help from the thermostat, and the app’s scan simply times out.Do yourself a favor, get at basic unit from a better vendor. From my experience, I would avoid anything by Copeland (formerly Emerson Climate Technologies). This thermostat is simply frustrating.

Great Value Recommended for Basic HVAC Setups
It’s a thermostat and does thermostat stuff. I don’t have a complicated setup. I have electric heat and AC and I have had no issues.Installing it myself was straight forward with the guided setup in the Sensi app. I use the Alexa integration And that also works well. One interesting thing to note is when asking Alexa the indoor temperature it is able to see half degree increments even though the display and app show only whole degree readings.In my state they have a smart thermostat rebate so I applied and got the full amount back so this didn’t cost me a penny.

I managed to get this working with my old brivis gas heating unit. This thermostat need C wire for gas heating.Old thermostat had only two wires. But the heater unit had C wire built-in which I rewired to connect to this thermostat to make it work.Setup is very straightforward. It’s being one month since I installed and working perfectly.Happy with thr product so far.Note that this is a US product and it has US units and location/ weather information is only related to US or Canada.But I use Alexa and Google Home to align with my location in AU.

Great thermostat but make sure you have the right hook ups and wiring on your old furnace before removing your old thermostat or you will be in for a headache, basically do your research before tearing things apart and watch plenty of videos. Thermostat works great once it was hooked up and being able to control from your phone is a blessing.

This shouldn’t be sold globally. You can’t use it as a smart device outside Canada and the US.

I had tried 2 different units of the same model and they both exhibited the same issues. The problem was a loss of wi fi signal and the system was going into off mode. Tried calling the help desk but was but on hold hearing the same message for 20 minutes. There was no message stating that there was a back log of customers. Appearance and simplicity I give it 5 stars but automated functionality I have to fail it.
