Struggling to figure this out. Any suggestions or advice?
If you don’t care of your local regulations for approved smoke/heat detectors, then Frient works nicely with Homey.
I even use the smoke alarm for the flood sensors I have, as you can toggle it on/off.
Next you struggle to find things, start with a search on the forum or on Homey’s apps. You’ll find many other Zigbee smoke alarms that work with Homey.
