I'm currently using a FortrezZ mimo2+ for z-wave monitoring of dry contacts and some output relays. works great, but at $80 each, it's not a cheap solution … even though it gets you two sensors.
I need four more dry contact monitoring points, and have an aversion to battery operated ones for this application (the contact points are already centrally wired, so I don't need the convenience, or maintenance overhead of battery power). Does anyone know if there any decent alternatives?, or any alternatives at all for that matter? (my searches keep coming up empty; everything is battery powered … it seems like this may be a z-wave unicorn)
