I’ve just moved into a house, and convinced my wife that we should go all-in for home automation. My VeraLite and a collection of starter gadgets is arriving tomorrow!
The previous owners used a Protection One security system. While the service has been discontinued, the wall unit is still there, with a little LED that goes out when any window or door is open. Every window and door appears to have a magnetic reed switch, neatly installed into the frame and painted over, so they are nearly invisible.
I would very much like to get access to that sensor data for my HA system. I don’t much care about monitored service, but with all the sensors so neatly installed, it’d be a colossal waste not to use them.
But I have no idea whether these sensors are wired through the walls, or some sort of wireless system. I’ve tried searching for the details, but my google-fu is not strong enough. Any ideas how I would go about figuring out how these sensors get power and communicate, and tapping into it for my own purposes?
