At first I felt that it was hard to finish the setup since the thermostat was installed by someone else. But just check your e-mail and follow the instructions. Don’t jump directly to the App, first agree with terms and follow the email instructions In general, it’s easy to deal with this thermostat. Just download the App and you will see it.
It's awesome to be able to set/adjust temperature when I'm in the basement or far side of house from where the thermostat is setting. I'm still learning about setting temps for different times of day
If you don’t plan on letting your local electricity provider control the temperature in your house, it might make sense to look elsewhere. If you register the device it wants access to your location via your phone at all times (bizarre, right?). If you don’t register the device it spams a message in your screen endlessly saying to register it and until you do you’ll never be able to just glance at it to tell the temp/settings, instead having to clear the spam message to get there.
The Wifi connection is nice. I'm very surprised that there isn't an auto setting where the AC or Heat will come on as necessary. During this time of year when the temp swings are a little more dramatic, I have to set the thermostat to heat at night and in the midafternoon turn it back to AC. The thermostat at my previous residence had an auto setting and I didn't have to worry with it once I had the schedule set.
Good for the operations it has however it needs to be able to do AUTO mode to switch automatically between heat and cold, at present i am either uncertain how to setup this mode on this device or it does not natively have it.
