Integrating with Home Alarm

If those are wired contacts they won’t work directly with ST.

There is a way to get them to work using specific Z-wave contact sensors. You just need to get the Ecolink or Schlage sensors and they have the ability to add in wired contacts. I believe I’ve seen done where you could do multiples in series if you had side-by-side windows you wanted to monitor (essentially monitoring 2 windows with 1 sensor)

and also this thread uses them (albeit for a different purpose, but same concept)
