5 stars: This app worked fine til latest update, using Samsung S8. It won't make or reflect changes to temp setpoints to either controller. It will only work if I reboot phone, then later won't work again...unless another reboot. Update: After the next update, problem went away, working fine now. Thanks. The app works very well, does everything I need to from my phone.
3 stars: The app is okay and okay. For both the app and the decide itself...I just wish there was a way to enter a temp without having to use the spider which can be appalling at certain times for some reason it another.
3 stars: So called smart thermostat doesn't support geofence for more than one person unless you're willing to give your data away to another company (Life360). Other than that it works fine.
3 stars: This app is a PITA. It's not user friendly or does it really make sense where to go to adjust your settings. I thought I turned my fan to \
3 stars: App having some issues since the latest version was released. Temp settings aren't reverting to the next schedule automatically. Eco+ mode seems work less effectively than the old follow me function. Also the app isn't refreshing properly shoeing old status. I have to shut down the app and then reopen for it to show the proper state if sensors and HVAC state.
4 stars: Good app, features, functionality, programming, performance, but still buggy at times. Overall, If you take the time to realize how much this ecobee 4 can do, especia...
