HM-WDS10-TH-O and HomeKit not compatible?

Hello!
I’m glad that so far everything works like a charm with HASS.
I was able to get all my Homematic stuff integrated and publish things I want with HomeKit.
The only thing I can’t get to work is the “sensor” named above. All the other thermal stuff is marked as “climate” and was easily accepted by HomeKit.
The documentation tells me that its need to be the following conditions:

All sensors that have % as their unit_of_measurement and humidity as their device_class.

And when I take a look at the attributes, I see that it looks like this:

Address: LEQ1000266:1
Model: HM-WDS10-TH-O
Entity type: generic
Parameter: HUMIDITY
Function: Weather
Value_state: valid
unit of measurement: '%'.
device_class: Humidity
friendly_name: outdoor sensor humidity

This is my configuration: (referenced in configuration.yaml)

  - name: HASS bridge 2
    port: 21065
  - Filter:
      include_entity_globs:
        - climate.*_wall_thermostat
        - light.*
        - cover.*
      include_entities:
        - input_boolean.swalarm
        - input_boolean.cinema
        - switch.kuche_switch_input
        - switch.reading_lampwz
        - sensor.outdoor_feeler_humidity
        - sensor.outdoor_temperature

Maybe some see somthing I dont see or knows somthing I don’t know and can help me out.
Many thx and cheers
Marco
