Abstract

Systems and techniques are provided for guided installation feedback for an opening sensor. Detected magnetic field strengths of a magnetic field created by a magnet of an opening sensor as detected by a magnetometer sensor of the opening sensor may be received over a time period. It may be determined that there has been a change in the strength of the magnetic field created by the magnet as detected by the magnetometer sensor based on the received detected magnetic field strengths. Accelerometer data from an accelerometer disposed in the magnetometer sensor may be received. It may be determined from the accelerometer data that the magnetometer sensor was not moving and positive feedback may be provided to an installer of the opening sensor, or it may be determined from the accelerometer data that the magnetometer sensor was moving and negative feedback may be provided to the installer of the opening sensor.
