Setting Away or Home on the Smart Thermostat
I believe that being able to set Away from the system itself would be handy and it can somehow relax dependency on geofencing.
For example, I go to my neighbor, I would like to go to my smart thermostat and press something and inform all other components of the system that I am actually leaving my house. At the moment this is only possible via the app and for every room separately. This would be something similar to the global off but slightly different because the heating can go to away mode which must not be also off mode.
I go to my neighbor and my phone is in the house.
So in my opinion, there should also be another dimension of abstraction, like floor. So, I go, i just set one dedicated smart thermostat to away and every room goes to away mode.
