v2022.0.6 made a change to the state:armed.
For better compatibility with the HomeKitLink-S plugin and the HomeKit app, removed Keypad device state:armed and replaced with state:armedAway and state:armedStay. If you have a trigger that relied on “Device State Changed > Keypad Device > Alarm State Changed to Armed” you need to reselect now one of the correct “ArmedStay” or “ArmedAway” states. All other triggers and events should work as before.
So either you have trigger that still looks for the no longer existing state:armed or your keypad device did not properly update to the new states. In this case, just opening and resaving the keypad device should fix this.
