Review on 🚀 Enhanced First Alert RM4 Intelligent Relay for Advanced Connectivity by Mensur Long

Works. I integrated this into my HomeSeer system via the HomeSeer ADIO-100 analog/digital system interface using BRK-RM4 "normally open" wires (connected to the digital I/O side of the ADIO). Fits snugly in the ceiling "box" of my First Alert smoke alarms, but no big deal. My smoke alarm's "test button" also triggers the same connection, so I was able to easily test the correct alarm and subsequent alerts in HomeSeer on my phone (using the excellent PushOver plugin).
