I'm a newbie just getting started with a Veraplus. Everythings been going well so far in setting up the controller and adding a few devices. I just have a quick question. I currently have a home brewed hard wired alarm system I put together many years ago. It's made up of door/window contacts, on/off switch, relays, timer, and a siren. I'd like to be able to get a notification on my phone if the siren turns on. So basically I'm looking for some type of zwave device that I can connect to the alarm system which will sense 120v AC from the siren or 12v DC from a relay when the alarm is triggered? Any recommendations?
