Smart wall switch controller

A smart-home system, comprising:

• a battery-powered smart home device that wirelessly communicates using a first communication protocol characterized by relatively low power usage and relatively low data rates;
• and
• a smart thermostat, comprising:
• electrical connections configured to be electrically connected with in-wall powered wiring;
• a user input component configured to receive user input;
• an electronic display configured to present at least a current setpoint temperature;
• an occupancy sensor;
• wireless communication circuitry comprising a first wireless interface and a second wireless interface, wherein:
• the first wireless interface is configured to communicate with the battery-powered smart home device using the first communication protocol;
• and
• the second wireless interface is configured to serve as a communication bridge between the battery-powered smart home device and a wireless network that uses a second communication protocol characterized by relatively higher power usage and relatively higher data rates;
• and
• a processor, in communication with the electronic display, the user input component, the wireless communication circuitry, and the occupancy sensor, wherein:
• the processor is configured to transmit occupancy information based on information received from the occupancy sensor via the wireless communication circuitry;
• and
• the smart thermostat is configured to be wall mounted and electrically connected with an HVAC system.
