I have Honeywell 5800PIR-RES Motion Sensors throughout my house, connected to a Vista-20P through Honeywell keypads. I know that there is a chance I could configure this system to work with Home Assistant using Alarm Decoder modules, but I was wondering if there was a way to access these sensors more directly to use them for home automation.
I would like to use them to help manage lighting and temperature in my house. My wife has earned the nickname “Tinkerbell” because she leaves a trail of light behind her (she never turns off lights when she leaves a room). So as an example, I would like to setup my motion sensors to recognize when someone is not in the room and configure an automation to turn off lights.
I’ve read that these sensors operate in the 345MHz range, so I assume a special receiver would be needed.
Has anyone accomplished this, or is what I’m doing more nuts than just integrating my Vista-20P into my Home Assistant program through Alarm Decoder?
