Smoke / heat detectors for HomeyPro 2023 that work in the US?

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.
