I honestly don't know how it would work as a Zone Expander. I think it listens for a Zone Expander to read Zone statues from but not be used as a Zone Expander. I typically buy Alarm Panel parts from Alarm liquidators. I have Gerber Files for a little Adapter board I made for my setup. You can have JLCPCB or PCBWay spin up some boards.
It emulates a zone expander for the panel. A zone can be triggered by calling the set_zone_fault service in home homeassistant . Eg
"set_zone_fault",Parameters: "zone","fault" where zone is a zone from 9 - 48 and fault is 0 or 1 (0=ok, 1=open) The zone number will depend on what your expander address is set to.
Or you can hardwire one of the unused esp inputs to be a trigger and have it send the set_zone_fault command internally. Example in the yaml.
The whole reason for this is that you can use any home assistant sensor . ie motion sensors, switches, camera motion,etc to trigger the alarm system by setting one of the emulated zones. This easily expands your security system to be triggered by anything you want.
Hi, Can you share on how this can be used as Zone Expander. I am planning to buy these WeMos D1 Mini and wire them as you shared or is there a ready to buy item that is available with your design?

Appreciate your guidance.
