Aqara smoke detector linkage alarm

I am having same issue…original battery lasted 2-3 years, then last two new batteries died withing 2-3 weeks. I have no other choice but to trash it.

This worked

Hi, I have been inspired by this blueprint and created my own after noticing some bugs. Mainly after starting to investigate how to integrate Self-Tests and Fire-Alarm tests I decided to completely write it from scratch.

Have a look here in the forum or head over directly to my github account.

Feature excerpt:

:white_check_mark: Notification driven self-tests of all detectors by one “click”
:white_check_mark: Real-Fire-Alarm test (uses the same path as on smoke detections)
:white_check_mark: First-Alarm notification to allow preventing false alarm propagation
:white_check_mark: Fire-Alarm propagation to all detectors
:white_check_mark: Persistant Fire-Alarm notification
:white_check_mark: Fire-Alarm Text-to-Speech (TTS) notification
:white_check_mark: Mute Alarm action on notification
:white_check_mark: Action on alarm
:white_check_mark: Wakeup detectors on tests and alarm

Hi mate, did you make it work? seems the linkage alarm switch doesn’t work, I have to use the linkage alarm via automation. what does the linkage alarm switch means though?

You need to put this on

yes, I did to both smoke alarms, when one is alarming but the another one didn’t go off.

Please try:

Let me know if that works for you.
