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:
Notification driven self-tests of all detectors by one “click”
Real-Fire-Alarm test (uses the same path as on smoke detections)
First-Alarm notification to allow preventing false alarm propagation
Fire-Alarm propagation to all detectors
Persistant Fire-Alarm notification
Fire-Alarm Text-to-Speech (TTS) notification
Mute Alarm action on notification
Action on alarm
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.
This works great!!! Thanks for putting this together.
