Installed the RBoy device handler and paired. It reads the battery and tamper switch, but no matter if movement or vibration, it always reads inactive.
Update - just figured out if the tamper switch is active, cover is off, it will not report any motion or vibration activity.
NOTE: If the device is shaken very violently, sometimes the “spring” mechanism inside the device could get “stuck” behind the capacitor in some devices which can cause it to stop sending further notifications until it is reset.
The new device handler from RBoy Apps works perfectly with the Monoprice shock sensors. The Smart Home Monitor portion of the Smartthings app recognizes them as motion sensors and will display an intrusion just as if a door/window switch was triggered. I recommend the RBoy Apps company and their support them without reservation.
