So I gave the [SM120X][1] / [RS100HC][2] config a try. It does physically work, but I am not happy with the implementation. For one it is a pain having that surface mount device wired in to the junction box of the smoke detector. Also the battery idea just doesn’t work well with me. I have placed the RS100HC on another door in the house and bought the [MIMOlite][3]. One thing I think will be really cool about the MIMOlite is that I can wire it up with the SM120X as a “pull alarm” and be able to set off the smoke detectors through smart things. I think it could be cool as a whole house intrusion alarm versus getting a [FortrezZ][6]. The MIMOlite will also power off of the 9v constant coming from the SM120X --- _[View the full topic](https://community.smartthings.com/t/mimolite-sensor-as-smoke-detector-device/1924)._
