When i say that imagination is the limit i mean it. I ordered some car seat pressure sensors and soldered them to either end of a door contact sensor and put them under our couch cushions. Now i have a battery powered, zigbee based, way to override the motion based automation if we’re on the couch. The lights stay on if we’re too still or they stay off if we’re napping and a pet walks in.

I watched a video where a guy used meshtastic to reach the back of his property and those radios can run on solar.
