A multi-function thermostat for a building includes a sensor configured to measure an environmental condition of a building space, a communication interface, and a processing circuit. The communications interface is configured to communicate with an emergency server and receive occupant health data from a health sensor configured to monitor an occupant. The processing circuit is configured to determine a health metric associated with the occupant based on the occupant health data and cause the communications interface to send a distress message to the emergency server when the health metric associated with the occupant indicates a medical emergency.
