Generic Hygrostat implementation

Greetings fellow users.

I was excited to see the new generic hygrostat in the latest version, and was looking forward to using it in my setup. I have it configured in my configuration.yaml as specified, but it doesn’t seem to automatically activate. I notice that I get a new “hygrostat” showing in my default dashboard, but it will only activate if I manually select a humidity value that is less than the currently detected value. Since it is so new, I can only find documentation on the configuration.

here is my relevant code:

generic_hygrostat:
  - name: Bathroom Humidity
    humidifier: switch.mb_exhaust_fan
    target_sensor: sensor.4_in_1_sensor_humidity
    device_class: "dehumidifier"
    wet_tolerance: 5
    min_humidity: 50
    max_humidity: 60
    target_humidity: 55

I had previously set up 2 separate automations that would control the fan at set values. I had hoped that the new native Humidifier would allow a smart response to seasonally adjusted humidity values, but it seems that it locks it to a user selected value that can be randomly changed outside the configured parameters.

here is a snip of the new interface in the overview, as you can see, the value of 57 is not relevant to the config.yaml options.

What am I missing to have the control of the switch that is specified?

Thanks in advance,
James
