Hi all,
I’m trying to confirm whether this is a known limitation or a bug specific to the Aqara M100.
Setup
- Aqara Hub M100
- Firmware 4.5.20_0027.0017
- Connected to Apple Home via HomeKit (not Matter-only)
- Door / motion sensors visible in both Aqara app and Apple Home
What works
- Arming / disarming syncs correctly to Apple Home
- HomeKit automations trigger correctly on Alarm Arms (Away/Home)
- Sensor events (door open/close, motion) appear in Apple Home activity
What does NOT work
- When the system is armed (Away) and a sensor triggers:
- Alarm does trigger in the Aqara app (siren + notifications)
- Apple Home never changes alarm state to “Triggered”
- Home app activity log shows:
- Alarm armed
- Sensor opened
- No “Alarm Triggered” event
- Any HomeKit automation based on “Alarm System → Triggers” never fires
Key observation
- In Apple Home hub settings, there is no “Alarm Trigger Devices” section.
- Because of this, HomeKit never correlates sensor events with the security system.
Expected behavior
- When armed and a permitted sensor is triggered, Apple Home should enter the Triggered state (as seen with older Aqara hubs like M1/M2), allowing trigger-based automations.
Question
- Is this a known limitation of the M100 HomeKit integration, or
- Is there a firmware update / configuration missing that enables alarm trigger propagation to HomeKit?
If other M100 users can confirm whether their alarm ever shows Triggered in Apple Home, that would be very helpful.
Thanks!
