This may be the worst UX of any app I have ever used. Every time I want to get in or out of vacation mode i find it almost impossible to figure out. All my thermostats randomly decided to engage child lock feature meaning they can no longer be adjusted on the thermostat itself. It is simply a frustrating experience all around.

Really poor experience with the app as most of the other reviewers are also mentioning. The hardware itself is perfect, but for some reason there seem to be no interest in getting the app on pair with their competitors like e.g. tado, which will probably make me switch for an easier control. Right now, I for example can't locate the pause button on half of my devices, and haven't been able to for a few months - major bug in my opinion. Only option I have is to manually decrease the heat.

Looks great, but there is a bug in the home integration. If temp is set to pause, Google homekit think the temp is set to day temp. Also, plenty of room for more features. Like showing how much each thermostat is open. And showing if window open is detected. And getting notifications for certain rooms, like the kids room. Would also be nice to get notifications if the kid turn the temp up. And all of this should be available in graph form!
