I am looking for a relay. I have previously used the Fortrezz MIMO lite for this solution, but they aren't sold anymore.
I am looking to wire a garage door opener into the relay, so it can be inside my house and open the garage door in our detached garage (it's about 150 feet away, so I am worried about getting a z-wave signal out there). I did this at my old house using a MIMOLite relay, and it worked great - took the cover off a spare opener remote, soldered the connection and plugged it into the MimioLite.
Even a Zooz ZEN51 can work depending on how you want to wire it up.
The nice thing about the ZEN16/17 is they are designed to be mounted outside of a box and run off DC power. Can be powered via USB or directly wired to a DC supply.
