My HE setup for HSM is several door contact sensors (Iris v3 x6) and keypads (Iris v2 x3). I've noticed strange behavior in the last couple months whereby I disarm HSM either via a keypad OR the dashboard, the dashboard says disarmed, but when a door is opened, I still get an alarm notification on the dashboard / app and one or a couple keypads are alarming. I've also noticed that when I arm HSM, the keypads do their arming acknowledgment beeps for 10 ish minutes off and on.
I have 4 keypad devices: 1 Xfinity, 2 Iris V2, 1 Iris V3 and have never experienced this condition. The only things I can think of that may cause this are: user defined modes, and or mis-configured HSM mode settings, or perhaps another app setting HSM's Status and HE's Mode.
Please Note: HSM adjusts HSM's arm state when the mode changes, suggest checking HSM's "Configure Arming/Disarming/Cancel Options" ---> "configure automatic arm/disarm" ---> Mode settings.
Update: one other thing to verify. Assuming the HSM system keypad drivers are being used, verify the keypads are defined in HSM's "Configure Arming/Disarming/Cancel Options" ---> "Use keypad(s) to arm/disarm"
