I have this contact sensor on a sliding door [photo]. The opening and closing of the sliding door would jolt the body of the Ring sensor apart from the base plate causing a "Tamper Error".

I mocked up this collar to secure the Ring contact sensor body to its base plate to prevent slippage during the opening and closing of a window/ door.

Print and slide onto the contact senor making sure it is pushed snuggly over where the back plate would protrude e.g. flush against the window frame or door
