5.0 out of 5 stars Replaced a VERY hard-to-program OLD unit
Reviewed in the United States on June 15, 2024
My former thermostat was not "smart". It was very dumb, in fact. Or maybe it was me that was the dumb one. This one is so easy to program, to change settings at the drop of a hat, and just, well, to keep up with my needs! I don't have any "smart" applicnaces yet - this is my first - and I'm hooked, at least on the thermostat. Thinking of a doorbell next. I like the economy features built in. It will track my temperature and turn on/turn off the A/C. It will remind me of filter changes (my other unit did, too, but it was just a flashing light that could be ANYTHING.) It's sleek, easy to install (except for the "C" wire, which my other thermostat didn't have so we had to use the included adapter in the furnace to hook it up so it would "read" always). Other than that, it is fitting into my very senior life beautifully. I'm so pleased. PLUS, I got a $75 rebate just a few days after installation. Solar panels and battery are due for installation next month, Xeriscaping my front yard will start next week, and now this thermostat! Wow! I don't know how I could get much more energy efficient. (Thirty-percent government rebate on the panels and a rebate on the battery, too. Doesn't get much better than that.)

5.0 out of 5 stars Finally a "Smart" Thermostat That Works!
Reviewed in the United States on August 7, 2023
To sum it up, this thermostat does what it is supposed to do (keep your home comfortable while maximizing energy savings and the environment). Installation was a breeze and the app functions well. End user settings are ADJUSTABLE for your specific home/system requirements. I have the AC temp go up during the day to 75 degrees. In less than a few days the thermostat “learned” how long my system takes to cool my house back down to a comfortable temperature before I return home. I have the swing temperature set to +1 degrees, which seems to be the appropriate level for my home. This allows an AC run time between 20-30 minutes before shutting down the call for cooling. My prior “smart” thermostat swing was set very “tight” and was not adjustable. This caused my cooling system to run for about five minutes or less and turn back on in about the same amount of time and repeated this cycle day and night unless I would manually adjust the temperature. I believe this may have caused issues with my previous 7-year-old single-stage AC compressor. Believe it or not, the +1-swing temp is WAY more comfortable than the previous 0.5-swing temperature. One thing I didn’t realize is the constant compressor on/off process also increased the humidity in my house by about 15%. This thermostat keeps my humidity in the 40% range which is way more comfortable than what the previous thermostat was achieving. I do not understand much about thermostats/HVAC systems and would not have believed a thermostat would have anything to do with the humidity level in the home. I should point out, prior to installing this thermostat, the humidity level in my house was not my main concern, I just notice it is drastically more comfortable after installing this thermostat and wanted to point out that fact.
All in all, I have learned a significant amount of HVAC terminology in the past month from the frustration caused by a previous ineffective smart thermostat. With this thermostat, you don’t need to be an HVAC technician to have equipment that operates effectively and/or to have a comfortable home. It is truly SMART.
My only negative complaint is the look and color. I wish they had a white color option. We have colored walls in our home with white trim/doors. I did prefer the look of the previous ineffective thermostat. The black color looks a little out of place on my wall! I still rate this thermostat as a five because it does what it is supposed to do. Aesthetics without proper function is a complete deal breaker!
I don't usually write too many reviews, but I had a horrible experience with a prior “smart” thermostat, and I would like users to understand thermostats are not all designed the same. If you are having difficulties with your system due to a dumb thermostat, I would highly recommend this product if you don’t mind the aesthetics.
