Descripción

status
Es el estado actual del sistema de HVAC del termostato.
string Valores: "OFF", "HEATING", "COOLING"
Momento de los eventos
Ten en cuenta que es posible que no se entregue un evento para un cambio en el estado del HVAC al mismo tiempo que los eventos para un cambio en el modo del termostato.
Por ejemplo, a veces hay una demora en el inicio del modo de calefacción o enfriamiento de un termostato para proteger el sistema de HVAC. En esta situación, cambiar el modo del termostato puede enviar inicialmente solo eventos para los cambios de rasgos ThermostatMode y ThermostatTemperatureSetpoint , y el cambio de rasgo ThermostatHvac se enviará más tarde como un evento independiente una vez que el sistema se encienda. Si no hubiera habido una demora en el encendido del sistema de HVAC, los tres eventos se habrían enviado al mismo tiempo.
