Abstract

A system and method of monitoring and controlling powered gas or electric appliances or devices using proximity awareness and providing optional watchdog safety shutoff capabilities including an inline or remote monitor and control system, radio awareness of compatible components such as Bluetooth smartphones and dongles, and optional Internet connectivity for remote monitoring, control, and usage data accumulation.

Claims

1. A method of controlling an appliance, the method implemented by a device external to the appliance and the method comprising:

determining that the appliance is consuming power using a sensor that is external to the appliance;

obtaining a list of identifiers of authorized radio-enabled devices, wherein operation of the appliance depends on at least one of the authorized radio-enabled devices being proximate to the appliance;

monitoring for presence of radio-enabled devices;

determining that none of the authorized radio-enabled devices are proximate to the appliance by comparing identifiers of any proximate radio-enabled devices to the list of identifiers of authorized radio-enabled devices;

starting a timer in response to determining that none of the authorized radio-enabled devices are proximate to the appliance;

transmitting a notification to a user device; and

causing the appliance to be disconnected from a power source in response to the timer reaching a limit.

2. The method of claim 1, wherein the appliance is selected from the group consisting of an electric-powered appliance, a natural gas-powered appliance, a geothermal-powered appliance, a solar-powered appliance, a gasoline-powered appliance, a diesel-powered appliance, a propane-powered appliance, and any combination thereof.

3. The method of claim 1, wherein the authorized radio-enabled devices comprise a dongle, a smartphone, a tablet computer, a personal digital assistant, a smartwatch, Google glasses, a laptop computer, a notebook computer, a fitness tracker, or a cellular telephone.

4. The method of claim 1 further comprising monitoring, by a third-party sensor, a condition proximate to the appliance.

5. The method of claim 1, wherein determining that none of the authorized radio-enabled devices are proximate to the appliance comprises determining that none of the authorized radio-enabled devices are within a pre-determined radius.

6. The method of claim 1, wherein transmitting the notification to the user device is based at least in part on a second timer reaching a second limit.

7. The method of claim 1, further comprising:

receiving a usage exception from the user device; and

in response to receiving the usage exception, resetting the timer or increasing the limit.

8. The method of claim 1 further comprising transmitting a notification to the user device that the appliance is in an on state.

9. The method of claim 1 further comprising transmitting a notification to the user device that the appliance has been disconnected from the power source.

10. The method of claim 1 further comprising:

monitoring at least one sensor external to the appliance; and

changing the operating state of the appliance using data received from the at least one sensor.

11. The method of claim 10, wherein the at least one sensor is a smoke alarm.

12. The method of claim 1 further comprising collecting data about the operating state of the appliance.

13. The method of claim 12 further comprising using the collected data to:

calculate risk for insurance purposes;

aggregate collected data for market intelligence;

develop manufactured products;

develop food products;

provide market and sales data to utility companies;

provide market and sales data to manufacturers;

or provide market and sales data to insurance companies.

14. A device for controlling an appliance, the device comprising:

a sensor that measures power consumption of the appliance;

a control device to engage or disengage a power source from the appliance;

a wireless communications port;

at least one processor;

at least one memory storing processor-executable instructions that, when executed by the at least one processor, cause the at least one processor to;

determine that the appliance is consuming power using data obtained from the sensor,

obtain a list of identifiers of authorized radio-enabled devices, wherein operation of the appliance depends on at least one of the authorized radio-enabled devices being proximate to the appliance;

monitor for presence of radio-enabled devices,

determine that none of the authorized radio-enabled devices are proximate to the appliance by comparing identifiers of any proximate radio-enabled devices to the list of identifiers of authorized radio-enabled devices;

start a timer in response to determining that none of the authorized radio-enabled devices are proximate,

transmit a notification to a user device, and

cause the appliance to be disconnected from the power source in response to the timer reaching a limit.

15. The device of claim 14, wherein the processor-executable instructions further cause the at least one processor to reset the timer in response to determining that an authorized radio-enabled device is proximate.

16. The device of claim 14, wherein the processor-executable instructions further cause the at least one processor to determine whether a usage exception is in place.

17. The device of claim 14, wherein the processor-executable instructions further cause the at least one processor to:

process a usage exception received from the user device, and

reset the timer or increase the limit.

18. The device of claim 14, wherein:

the sensor comprises a voltage sensor, a current sensor, or a flow sensor, and

the control device comprises an electrical switch or a valve.

19. The device of claim 14, wherein the processor-executable instructions further cause the at least one processor to:

start a second timer, and

transmit the notification to the user device in response to the second timer reaching a second limit.

20. The device of claim 14, wherein the processor-executable instructions further cause the at least one processor to transmit a second notification to the user device after causing the appliance to be disconnected from the power source.

21. At least one non-transitory computer-readable medium comprising computer executable instructions that, when executed, cause one or more processors to perform actions comprising:

determining that an appliance is consuming power;

obtaining a list of identifiers of authorized radio-enabled devices, wherein operation of the appliance depends on at least one of the authorized radio-enabled devices being proximate to the appliance;

monitoring for presence of radio-enabled devices;

determining that none of the authorized radio-enabled devices are proximate to the appliance;

starting a timer in response to determining that none of the authorized radio-enabled devices are proximate to the appliance;

transmitting a notification to a user device; and

causing the appliance to be disconnected from a power source in response to the timer reaching a limit.

22. The at least one non-transitory computer-readable medium of claim 21, the actions further comprising resetting the timer in response to determining that an authorized radio-enabled device is proximate to the appliance.
