This trait belongs to device types of THERMOSTAT that can report HVAC details.
Fields
Field
Description
Data Type
status
Current HVAC status of the thermostat.
string Values: "OFF", "HEATING", "COOLING"
Timing of events
Note that an event for a change in HVAC status may not be delivered at the same time as events
for a thermostat mode change.
For example, sometimes there is
a
delay in starting a thermostat's heating or cooling mode in order to protect the HVAC
system. In this scenario, changing the thermostat mode may only initially send events for
ThermostatMode and
ThermostatTemperatureSetpoint trait changes, with the
ThermostatHvac trait change sent later as a separate
event once the system actually turns on. If there was no delay in turning on the HVAC system, all
three events would be sent at the same time.
