Abstract

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.

First claim

The invention claimed is:

1. A system, comprising: a sensor fixed to an enclosure of a moveable partition; and a processor configured to: receive a first signal from the sensor that indicates a movement of the moveable partition, determine, based on the first signal, that the moveable partition has moved less than a first threshold distance into a semi-open position, receive a request to place a home security system into an away mode, and place the home security system into the away mode based on the determination that the first signal indicates that the moveable partition has moved less than the first threshold distance into the semi-open position.

2. The system of claim 1 , wherein the sensor is a compass.

3. The system of claim 1 , wherein the first signal further indicates an orientation of the moveable partition.

4. The system of claim 3 , wherein the first threshold distance is determined based on the first signal indicating that the moveable partition moved a threshold number of degrees relative to a closed position.

5. The system of claim 1 , wherein the sensor is an accelerometer.

6. The system of claim 5 , wherein the first signal further indicates a speed at which the moveable partition is moving.

7. The system of claim 1 , wherein the processor is further configured to generate a notice that indicates that the home security system is in the away mode and that the moveable partition is in the semi-open position.

8. The system of claim 1 , wherein the processor is further configured to:
detect that the semi-open movable partition has moved a distance greater than a threshold distance based on a second signal from the sensor while the home security system is in the away mode; and
generate a notice that indicates a movement has occurred.

9. The system of claim 1 , wherein the moveable partition is a window.

10. A computer implemented method, comprising: receiving a first signal from a sensor that indicates a movement of a moveable partition; determining, based on the first signal, that the moveable partition has moved less than a first threshold distance into a semi-open position; receiving a request to place a home security system into an away mode; and placing the home security system into the away mode based on the determination that the first signal indicates that the moveable partition has moved less than the first threshold distance into the semi-open position.

11. The method of claim 10 , wherein the sensor is a compass.

12. The method of claim 11 , wherein the first signal further indicates an orientation of the moveable partition.

13. The method of claim 12 , wherein the first threshold distance is determined based on the first signal indicating that the moveable partition moved a threshold number of degrees relative to a closed position.

14. The method of claim 10 , wherein the sensor is an accelerometer.

15. The method of claim 14 , wherein the first signal further indicates a speed at which the moveable partition is moving.

16. The method of claim 10 , further comprising generating a notice that indicates that the home security system is in the away mode and that the moveable partition is in a semi open position.

17. The method of claim 10 , further comprising: detecting that the semi-open movable partition has moved a distance greater than a threshold distance based on a second signal from the sensor while the home security system is in the away mode; and generating a notice that indicates a movement has occurred.

18. The method of claim 10 , wherein the moveable partition is a window.
