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.

Claims

1. A system, comprising:

a first sensor affixed to a moveable partition;

one or more secondary sensors at or around the moveable partition;

a memory device; and

a processor configured to;

sample, at a first time period, a first signal from the first sensor that indicates a position of the moveable partition,

determine, based on the first signal, that the moveable partition is in an open position,

receive a request to place a home security system into an away mode,

place the home security system into the away mode based on the request to place a home security system into an away mode and subsequent to determining that the moveable partition is in an open position,

receive a second signal from the one or more secondary sensors that indicates a movement detected at or near the moveable partition that is in the open position, and

generate a notice alerting a user of the movement detected at or near the moveable partition.

2. The system of claim 1, wherein the one or more secondary sensors include a motion detector.

3. The system of claim 1, wherein the one or more secondary sensors include a light sensor.

4. The system of claim 1, wherein the processor is further configured to:

store data generated by the first sensor and the one or more secondary sensors in the memory device,

determine a pattern of activity regarding the movable partition based on the data,

determine, before generating the notice, that the detected movement matches the pattern of activity, and

forgo generating the notice based on the determination that the detected movement matches the pattern of activity.

5. The system of claim 4, wherein the pattern of activity is determined based on data from at least two different sensors.

6. The system of claim 4, wherein the first sensor is a compass and the first signal further indicates an orientation of the moveable partition.

7. The system of claim 4, wherein the first sensor is an accelerometer and the first signal further indicates a speed at which the moveable partition is moving.

8. 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 an open position.

9. The system of claim 1, wherein the processor is further configured to:

detect that the open movable partition has moved a distance greater than a threshold distance based on a third signal from the first sensor while the home security system is in the away mode; and

generate a notice that indicates a movement of the movable partition has occurred.

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

11. The system of claim 1, wherein the moveable partition is a door.

12. The system of claim 1, wherein the processor is further configured to:

sample, at a second time period, the first signal from the first sensor in response to receiving the second signal,

determine, based on the first signal during the second time period, that the moveable partition has moved from the open position to a semi-open position,

wherein generating the notice is based on the determining that the moveable partition has moved from the open position to the semi-open position.

13. A computer implemented method, comprising:

sampling, at a first time period, a first signal from a first 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 an open position;

receiving a request to place a home security system into an away mode;

placing the home security system into the away mode based on the request to place a home security system into an away mode and subsequent to determining that the moveable partition has moved into an open position;

receiving a second signal from one or more secondary sensors that indicates a movement detected at or near the moveable partition that is in the open position; and

generating a notice alerting a user of the movement detected at or near the moveable partition.

14. The method of claim 13, wherein the one or more secondary sensors include a motion detector.

15. The method of claim 13, wherein the one or more secondary sensors include a light sensor.

16. The method of claim 13, wherein the processor is further configured to:

store data generated by the first sensor and the one or more secondary sensors in the memory device,

determine a pattern of activity regarding the movable partition based on the data,

determine, before generating the notice, that the detected movement matches the pattern of activity, and

forgo generating the notice based on the determination that the detected movement matches the pattern of activity.

17. The method of claim 16, wherein the pattern of activity is determined based on data from at least two different sensors.

18. The method of claim 16, wherein the first sensor is a compass and the first signal further indicates an orientation of the moveable partition.

19. The method of claim 16, wherein the first sensor is an accelerometer and the first signal further indicates a speed at which the moveable partition is moving.

20. The method of claim 13, 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 an open position.

21. The method of claim 13, wherein the processor is further configured to:

detect that the open movable partition has moved a distance greater than a threshold distance based on a third signal from the first sensor while the home security system is in the away mode; and

generate a notice that indicates a movement of the movable partition has occurred.

22. The method of claim 13, wherein the moveable partition is a window.

23. The method of claim 13, wherein the moveable partition is a door.

24. The method of claim 13, further comprising:

sampling, at a second time period, the first signal from the first sensor in response to receiving the second signal; and

determining, based on the first signal during the second time period, that the moveable partition has moved from the open position to a semi-open position,

wherein generating the notice is based on the determining that the moveable partition has moved from the open position to the semi-open position.
