[eusblh]

In case you missed it, there’s good info here. Read the whole thread. Note, it’s from 2015 ish, so all code is now in the official release.

First Alert ZCOMBO Working Instance?

Perform the z-wave binding sequence as documented in the manual, but do not put the controller into include mode. Basically, pull the battery tray out, hold the test button down while you slide the battery tray back in, and keep it held until you hear the beep. This causes it to wake up, and you should have a XML file at that point.
