I have Smart Home Monitor configured with two presence devices for me- my iOS phone and a Zigbee arrival sensor. The idea is that the phone presence is generally most reliable, but if my phone battery dies or if the Samsung cloud backend is down, my presence fob will disarm SHM and run my arrival routines in smart lighting.
During the platform outage today, I got home and SHM activated when I went into the house. Am I mistaken that the ST Zigbee arrival (presence) fobs should be able to disarm SHM locally without any cloud processing? Or is that not the case?
