What WiFi smoke detector can still be integrated with SmartThings, IFTTT, and/or Alexa?
I bought a First Alert One Link Safe and Sound because they said you can do automations through Alexa. You can’t.
I then bought a Google Nest Protect because it was supposed to work with IFTTT and Alexa. As of Aug 2019 it no longer does (I do not have a old Nest account). There are also a bunch of defunct Smart Smoke detectors out there. 
So in 2020 are there any WiFi smoke detectors that can be integrated with SmartThings?
BTW, it has to be WiFi because this is for my detached garage and even Z-Wave Plus will not reach. I have a FirstAlert ZCombo smoke alarm in the house that works well, but will not work in the garage. Yes, I have tried everything possible to get ZWave to the garage with no luck, I’m out of hops. I have ran ethernet to the garage and put in a WiFi router so I have strong fast WiFi there. I do have some Zigbee devices out in the garage, but they work most of the time, but not always. So Zigbee Smoke Detector would be a last resort if available.
Thanks!
