fire alarm system for home
, thermal radiation sensors, carbon monoxide/dioxide sensors, occupancy/motion sensors, ambient light sensors, ambient temperature sensors, humidity sensors, and the like. Furthermore, smart hazard detectors 104 may send messages that correspond to each of the respective sensors to the other devices and/or the server system 164, such as by using the mesh network as described above. As explained above with reference to FIG. 1, in some implementations, the smart home environment 100 of FIG. 1 includes a hub device 180 that is communicatively coupled to the networks 162 directly or via the network interface 160. The hub device 180 is further communicatively coupled to one or more of the smart devices using a radio communication network that is available at least in the smart home environment 100.
