Hi - I have a mixed X10 and Insteon system, with the old X10 security system (the one they sold several years ago). My house was wired with an ADT system that I don't use, and disabled, but I'm wondering if there's any way to use the keypad with my system. Has anyone ever looked at what kind of signals/outputs are available from the keypads to see if one could be modified and used with a powerline interface of some kind to produce something that could be sent to X10?
Similarly, ADEMCO has some nice sensors (eg fixed heat/rate of rise sensor) - wondering if there's any way to modify them to work with one of the wireless transmitters from the X10 security system. (DS10a or something like that?). I've been able to interface water sensors with those transmitter modules, wondering if other sensors can be used.
Thanks!
Michael
