I agree with this so much. Opening an app is the last thing I want to do to adjust something while I'm in bed. I have a zigbee lightswitch so I can turn the light off from bed, and sure I could open an app to do that, but it's so much better to get a zigbee button and stick it to the wall above my head and program it to control the lightswitch.

Unlike all the cloud garbage, my zigbee devices continue to function even when the internet is down. I have my zigbee hub (Home Assistant Yellow) on a battery backup, so all the zigbee devices with a battery keep functioning even when the power is out (like my automatic cat feeders)
