Aqara Side Door Sensor Mount

Changed sensors to control an LED strip light so redesigned to accomodate. This one is slightly shaped to grip, but intended to screw into the hidden side of the door near the hinges 
[but could go on the opening side]. Holds together more when sensor is in place. Fits an Aqara Door & Window Sensor.

Just to add, you might need to mirror the body part depending on the opening direction of your door and where you intend to fit it. I'll upload the alternate part at some point.
