Thank you @rlkoshak … you always have very valuable information :).
Here are some pics of the various ADT components in my house:
- Typical Motion Sensor (PIR ?)
- Control Box, by the garage door
- Typical Door Sensor
- Master Circuit/Panel, in the basement
My initial thinking was to find a way to hack into the board/controller but that will likely be a frustrating activity. At the very least, I think re-using the sensors might be the more ‘reasonable’ approach. Yes, I also have few RPIs and maybe now is the time to put them to good use.
