Hi, I’m trying to associate Heatit Z-smoke detector such that one detector triggers siren on the other detectors as well. From my understanding I should put the Node ID for the associated detectors in group 2, as seen in the attached image, but it does not work. Can somebody tell me what I’m doing wrong? ![IMG_8054](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/4/948ba48adccb125fff9ff708cd1bb37769e2e5bb.png) ---

You have to wake up the detectors before they can receive the new settings. In your case pressing the test button once should wake the detectors. Then you should press save settings on each of the detectors inside Homey, that should do it. (My detectors (Fibaro) only wake up every 6 hours to make contact with Homey and send/receive status, unless there is an alarm occuring) ---

Gravedigger here - did you ever get this working? I woke them all up before saving, even though they’re 230V - but testing with 1 click does not trigger sound in the others.
