Expose ecobee thermostat/sensor partticipation

The ecobee integration exposes a temperature sensor for the thermostat as well as each remote sensor. It would be nice if as an attribute on these sensors it included whether the sensor was participating in the current comfort setting. This would be very helpful for automations. For example, I’d like an automation to manually turn on the fan in the event that the temperature spread between all participating sensors exceeds a certain value.
