The method also includes analyzing the sensed information to identify historical information regarding the area that includes the controllable device. The method also includes sensing a condition within the area by the one or more sensory nodes. The method also includes determining, based at least in part on the sensed condition and at least in part on the historical information, that the sensed condition relates to the controllable device. The method further includes generating, responsive to said determining, an alert regarding the controllable device. ## Claims ### Claim 1 A method for monitoring devices comprising: sensing, by one or more sensory nodes, information in an area; determining, by a processor, that the area includes a controllable device; identifying, by the one or more sensory nodes, a condition in the area based on the sensed information; determining, by the processor, that the controllable device is within a predefined threshold proximity to the one or more sensory nodes that have identified the condition; sending, by the processor, an alert to a user device; and in response to the determination that the controllable device is within the predefined threshold proximity and in response to historical information regarding previously sensed conditions of the area, sending, by at least one of the processor or the user device, a control signal to the controllable device in response to identifying the condition, wherein the control signal causes the controllable device to enter an off state. ### Claim 2 (depends on 1) The method of claim 1, wherein sending a control signal to the one or more controllable devices is based, at least in part, on an occupancy of the area. ### Claim 3 (depends on 1) The method of claim 1, further comprising determining trends in the sensed information, wherein the trends are based on previously sensed information within the area. ### Claim 4 (depends on 3) The method of claim 3, wherein determining a condition is, at least in part, based on the determined trends in the sensed information. ### Claim 5 (depends on 1) The method of claim 1, wherein sending a control signal to the one or more controllable devices is, at least in part, based on a type of identified condition. ### Claim 6 (depends on 1) The method of claim 1, further comprising determining a severity of the identified condition. ### Claim 7 (depends on 6) The method of claim 6, further comprising sending a control signal to the one or more controllable devices upon identifying a condition if the severity of the identified condition is above a predetermined threshold. ### Claim 8 (depends on 1) The method of claim 1, wherein sending a control signal to the one or more controllable devices is, at least in part, based on a location of a sensory node of the one or more sensory nodes that identified the condition. ### Claim 9 (depends on 1) The method of claim 1, further comprising sending a status request signal to each of the one or more controllable devices, wherein the status request signal determines a state of each of the one or more controllable devices. ### Claim 10 (depends on 9) The method of claim 9, wherein sending a control signal to the one or more controllable devices is, at least in part, based on the state of each of the one or more controllable devices. ### Claim 11 (depends on 1) The method of claim 1, further comprising sending an alert to a user device regarding the identified condition. ### Claim 12 (depends on 11) The method of claim 11, wherein sending a control signal to the one or more controllable devices is executed by the user device. ### Claim 13 A system comprising: one or more sensory nodes configured to: sense information in an area that includes one or more controllable devices; and identify a condition within the area, based on the sensed information; a processor that is configured to: determine that the one or more controllable devices are within a predefined threshold proximity to the one or more sensory nodes; responsive to determining that the one or more controllable device are within the predefined threshold proximity and responsive to historical information regarding previously sensed conditions of the area, generate an alert regarding the one or more controllable devices in response to determining the proximity of the one or more controllable devices; send the alert to a user device; and a user device configured to send a control signal to the one or more controllable devices, responsive to the sent alert, that causes the one or more controllable devices to go into an off state. ### Claim 14 (depends on 13) The system of claim 13, wherein the user device is configured to send the control signal to the one or more controllable devices based, at least in part, on an occupancy of the area. ### Claim 15 (depends on 13) The system of claim 13, wherein the one or more sensory nodes are further configured to determine trends in the sensed information, wherein the trends are based on previously sensed information within the area. ### Claim 16 (depends on 13) The system of claim 13, wherein the one or more sensory nodes are further configured to identify a condition within the area based on the trends in the sensed information. ### Claim 17 (depends on 13) The system of claim 13, wherein the user device is configured to send a control signal to the one or more controllable devices based, at least in part, on a type of identified condition. ### Claim 18 (depends on 13) The system of claim 13, further comprising a transmitter configured to transmit the alert to a control unit of the controllable device. ### Claim 19 (depends on 13) The system of claim 13, wherein the proximity is based on a predefined threshold. ### Claim 20 (depends on 13) The system of claim 13, wherein the user device is configured to send the control signal to the one or more controllable devices based at least in part on the state of each of the one or more controllable devices. ### Claim 21 (depends on 1) The method of claim 1, further comprising: determining a status of the controllable device based on a broadcast status indicator signal associated with the controllable device; and in response to the broadcast status indicator signal, sending the control signal to the controllable device.
