@iEnam I noticed in another thread a member installed the wall version of what I'm going to assume is the 5.8G version.
I thought this was interesting.
They installed a copper plate behind the sensor to shield it from sensing from behind. I would not have guessed behind and I'm curious about what that might look like.
FWIW: I noticed the primary different between the wall version and the one you have is that the non wall version has a siren.
