I’m sure this has been done before but I know I’ve seen lots of discussions on the best way to integrate existing smoke/CO sensors into SmartThings. After lots of research I did what I thought was the best way for my situation and figured I’d write up what I did in case it could help someone else. …

What I’ve noticed is that after you make a change like that, you have to trip it a couple of times for it to sort of take effect and reflect the right status, even when doing it via hardware instead of in the handler. So try testing it a couple more times and see if the result flips the way you expe…

Thanks for all the help…I think it is working fine now. After my first few triggers, it was still reporting reverse, so I went back in and toggled back to the original and triggered a few more times and now it works as expected. Thanks for the help!! So what is the handler you are making for this…

I just submitted a pull request that updates these 2 device types for the newer SmartThings UI. Everything is moving this way so wanted to keep things consistent. Accept, reject, whatever you want but thought anyone using these would appreciate the continuity.

Changes merged and committed. Thanks! People using this device type should be able to pull the update from the IDE.

I have all CO/Smoke Combo detectors in my house, does it distinguish between the two with the single wire that runs between them or do I just pick one or the other and get the relay for that?

It sends a different single for each. So to integrate both you need both sensors. With that said you could “cheat” and tie both sensors into the same contact closure and save yourself $30 but then you wouldn’t know if it was really smoke or CO.

A+ project Allan. About an hour of work, less than $40 in components. More effective than the $80 pair of first alert zwave monitors I returned. Kid tested, mom approved. [image]

Thanks for creating your device handlers (and this guide in general). I’m having one issue though: the smoke sensor shows up in Smart Home Monitor but the CO sensor does not. Is there something special I need to do?

There was a slight issue in the “Smoke” device type. It worked for SHM/alerts but the screen didn’t update for smoke. It’s been fixed…please update your device type for the smoke when you get a chance:
