Default the sensors state never expires. Note that when a sensor's value was sent retained to the MQTT broker, the last value sent will be replayed by the MQTT broker when Home Assistant restarts or is reloaded. As this could cause the sensor become available with an expired state it is not recommended to retain sensor's state payload at the MQTT broker. Home Assistant will store and restore the sensor's state for you and calculate the remaining time to retain the sensor's state before it becomes unavailable.
