Smart-home control system providing HVAC system dependent responses to hazard detection events

A smart-home environment comprising:

• a climate control system responsive to signals from a system controller, the climate control system including a combustion based heat source;
• and
• a plurality of smart devices that are configured to communicate with each other using a low-powered wireless communication protocol, the plurality of smart devices comprising a plurality of hazard detectors and a spokesman node, wherein:
• a hazard detector of the plurality of hazard detectors is configured to:
• measure a level of carbon monoxide (CO) at a location of the hazard detector, and
• transmit, via the low-power wireless communication protocol and a low-power wireless communication network, an indication of the measured level of CO at the hazard detector to one or more other smart devices of the plurality of smart devices;
• the spokesman node is configured to:
• translate the indication of the measured level of CO at the hazard detector from the low-power wireless communication protocol to a second wireless communication protocol;
• and
• transmit the indication of the measured level of CO at the hazard detector to a system controller via a high-power wireless communication network and the second wireless communication protocol;
• and
• the system controller configured to transmit a signal to turn off at least one aspect of the climate control system responsive to the measured level of CO.

A method for controlling a climate control system of a smart-home environment that includes a plurality of smart devices, the plurality of smart devices comprises a plurality of hazard detectors, the method comprising:

• detecting, by a hazard detector of the smart devices, a level of carbon monoxide (CO) at the hazard detector that exceeds a threshold CO level at a location of the hazard detector;
• transmitting, by the hazard detector of the plurality of hazard detectors, via a low-power wireless communication protocol and a low-power wireless communication network, an indication of the detected level of CO at the hazard detector that exceeds the threshold CO level to one or more other smart devices of the plurality of smart devices;
• translating, by a second hazard detector functioning as a spokesman node of the low-power wireless communication network, the indication of the detected level of CO at the hazard detector that exceeds the threshold CO level from the low-power wireless communication protocol to a second wireless communication protocol, wherein the one or more other smart devices of the plurality of smart devices comprises the spokesman node;
• transmitting, by the second hazard detector functioning as the spokesman node of the low-power wireless communication network, the indication of the detected level of CO at the hazard detector that exceeds the threshold CO level to a system controller via a high-power wireless communication network and the second wireless communication protocol;
• determining, by one of the smart devices, that the level of CO at the hazard detector may be associated with operation of the climate control system;
• and
• in response to the detecting and the determination, transmitting, by the system controller of the smart devices, a first signal to turn off at least one aspect of the climate control system.
