Alarm arming with open entry point
A magnet and magnetometer may be integrated into a smart home environment and allow it to be placed into an away mode of operation despite an entry point being semi-open. The disclosed implementations can detect a magnetic field strength and determine, based on the detected field strength, an approximate distance that a moveable partition is open. In some configurations, the presence of a second magnetic source can be detected. A notice may be generated based on one or more signals received from the magnetometer. The notice may be sent to a controller, a remote system, a remote device, and/or a client device as disclosed herein.
1. A system, comprising
a magnet fixed to an enclosure of a moveable partition; and

determine that the magnetometer signal indicates a magnetic field strength less than a magnetic field strength corresponding to a closed moveable partition position and greater than a threshold magnetic field strength corresponding to a semi-open moveable partition position;
receive a request to place a home security system into an away mode; and
based on the determination that the magnetometer signal indicates a magnetic field strength less than a magnetic field strength corresponding to the closed moveable partition position and greater than a threshold magnetic field strength corresponding to a semi-open moveable partition position, place the home security system into the away mode.
