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. Cost me less then $100 and about 6 - 8 hours of work, probably less if I didn’t write this up and take pictures.

My house was built two years ago and has sensors to meet code. That means smoke in each of the three bedrooms, a combination smoke/CO in the upstairs hallway, a smoke in the first floor hallway near the kitchen, and another smoke in the basement. They are all Kidde brand and int…
