I was just looking at this device as a potential relay for a water shutoff valve. From the spec it doesn’t look like there is anyway to use both a hardwired switch and this unit together. It does seem to work with the WT00Z-1 remote switch though, if that will work in your case. Take a look at this post for more info: Evolve LTM-5 transmitter to LRM-AS association - #4 by mrmatt57
