We had a smart analog thermostat before, worked well but had some glitches, had been installed for like 8 years so decided to upgrade.Install was easy, but for sure needed the backplate which is sold separately. Great service from getting me that the same day.Once I had the the installation was pretty simple, was able to reuse the old mounting which was great due to the paint in that area not matching the rest. Will still have to do some touch up in that regard but no big deal.Since I had installed smart thermostats before it was no big deal, but the key here is to install Google Home on your phone BEFORE you start the installation. It will literally take you through it step by step. I did not need that but if you are not as familiar with this it is really helpful. Once I got through that, it auto-updated its software, entering a schedule using Google Home was easy. Have not yet added additional family members, looks like they also need to have Google Home installed on their phone for some of the more advanced features to work. It is easier to make adjustments on your phone than on the display.Happy so far, installed yesterday but all is working well.
