I want to setup aan alarm system; I have 2 tagreaders (benext), the idea is to have one near the front door and one near the backdoor to arm and disarm. The tagreaders seem to keep their status instead of sending on or off, how can I accomplish that I arm with one tag reader and disarm with the other? Since the other thinks it is disarmed, it doesn’t send a disarm event
