Make it possible to disable a device and/or a zone with all devices in it.
I have some devices which I only use and connect for example with Christmas, and the rest of the year they are in the drawer. Homey keeps looking for devices, I see errors in group devices and in flows. Of course I disabled the flows which are not needed at this moment, but still I see errors due to the fact that for the Homey the devices are unreachable.
Same for a situation you want to disable all sensors and devices in a specific zone, due to maintenance, construction work, and so on.
