I believe I understood what you mean but I didn't find the message you referred to.
My goal is to replace my old wired alarm with Domoticz and PiFace2 keeping my wired sensor (safer). I still have to find a way to arm/disarm the system. Up to now I didn't find such a device. If I can decypher Wiegand message I'll probably be able to use an access control device used for magnetic lock.
Thank you to both of you
Kind regards
Michel
