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

  • detecting, with a hazard detector of the plurality of hazard detectors, 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 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 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 climate control system includes a combustion based heat source; and

    in response to the detecting and the determination, transmitting, by the system controller of the climate control system, a first signal to turn off at least one aspect of the climate control system.
