So I got one of the brand new Heiman Smoke detectors (HS1SA-M) and integrated it via Thread.
What a pain 
- but that is a different story!
My real question is ---- has anybody found a way to silence an alarm via HA?
I cannot find a “switch” entity or “button” ???
While you can initiate a test alarm via a button in HA - there is nothing to switch the bloody thing OFF?
Please help - getting quite frustrated after 2h of getting Thread to talk to my Android phone !
