Don't make the mistake to buy this. Controlling it from the distance via your phone works for a day, and then it stops. As someone said in the reviews before, the communication happens via the honeywell server, and it drops regularly between the thermostat and their server. Once it drops, it doesn't restart by itself, I have to manually delete the device via the app, and do again the wifi setup. Yes, it doesn't even remember the wifi details. They have messed up bad with this product. Some of the settings on it are useless, the mobile apps for Android and IOS are buggy. Because of the geofencing function your phone battery will need to be recharged twice a day. It is a really bad product. There should be a recall and a refund to everybody. It makes me think that all the good reviews have been placed by honeywell salespeople.
