Abstract

Systems and techniques are provided for guided installation of an opening sensor. A strength of a magnetic field created by a magnet of an opening sensor at a location of a magnetometer sensor of the opening sensor may be determined. Feedback may be provided to an installer of the opening sensor based on the determined strength of the magnetic field. A function of the opening sensor may be configured based on the determined strength of the magnetic field. The function may be associated with reporting the status of an entry point to which the magnetometer sensor may be affixed.
