How to use schedy generic actor

Hi, everybody,
I’m trying to use the “actor_type: generic” in Schedy, but I can’t get it working.
(The “actor_type: thermostat” is working in my setup, so I’m shure, Schedy is working)
The goal is simle: I would like to position the roller shutter to 70% every day at a given time.
Here is my code:

schedy_roller_shutter:
  module: hass_apps_loader
  class: SchedyApp
  actor_type: generic
  attributes:
    position: null
    values:
      _other_:
        service: cover.set_cover_position
        service_data: {}
        include_entity_id: true
        value_parameter: position
    rooms:
      nappali_1:
        actors:
          cover.rsh02:
      schedule:
      - { v: 70, start: "20:25" }

After saving, the log returns:

2019-11-05 20:29:44.947486 INFO schedy_roller_shutter: --- Actor type is: 'generic'
2019-11-05 20:29:44.974955 INFO schedy_roller_shutter: --> [R:nappali_1] [A:cover.rsh02] Received value of ().
2019-11-05 20:29:45.242097 INFO schedy_roller_shutter: *** Initialization done.

And nothing happens :frowning:
If I call the cover.set_cover_position manually it works.
Please help me to get out from this “dead-end”

I think it’s better to ask in the Schedy topic.
