I noticed that my Ecobee's humidity isn't coming over to HE. I have selected the child entities for my Ecobee thermostats, example for my "upstairs" thermostat:
But it has been several days and there isn't a child Generic Component Humidity Sensor device for any of my thermostats and I know Humidity has changed.
With debug logging on, I see "current_humidity" coming over with the climate entity but know the Generic Component Thermostat doesn't have the RelativeHumidityMeasurement so expect a child humidity device to be created.
On a separate note, I did request that humidity be added to the component thermostat driver but Mike suggested a new combined driver be created.
