Fun project. Replaced an old hardwired FBII system with 6 zones and 25 sensors, 2 motion detections and one glass break sensor. I split it into 12 zones, and am using SmartThings to monitor. I tried monitoring with Google Home, but the SmartThings security monitoring app is just too easy to use. Thanks Konnected.
I replaced my FBII system with a Konnnected Pro. Have it working perfectly with HomeKit\Homebridge. Left my FBII board in place but doesn't have any power.
Added a quick example vid of the system working in iOS Home App via Homebridge. I moved my sensors to a room called "Security Panel".
My home security is now iOS\Internet enabled after 22 years in the house! Thanks Konnected!
