Cover.stop_cover don't working for Tradfri cover

Configuration
1

I use the Hue Dimmer with Deconz in my setup. I want use it for controlling the Blinds from Ikea.

The action (Kitchen Button 2) for opening the cover is working. But the stop_cover service from https://www.home-assistant.io/integrations/cover/ is not working for the Button. What is my mistake? Should I go with a script solution? Can anybody help me, many thanks.

Does manually triggering the Kitchen Button 1 Long automation work? Also you can clean up that automation a bit by changing the action block to this:

  action:
  - service: cover.stop_cover
    entity_id: cover.tradfri_blind

If manually triggering the automation works, check that the trigger has the correct data. Could also try manually calling the cover.stop_cover service for that cover in Developer Tools > Services.

it is very strange. the command cover.stop_cover for the service in Developer Tools > Services does not go through the console, so no reaction.

Edit:
I tested it with a Z-WAVE Roller Shutter, here it works. It must be a problem with the Integration of the IKEA Tradfri Blinds.

Seems that this https://github.com/home-assistant/home-assistant/commit/ec478ab8487f0ccd6ac9e1c488f0d217087adc94 not more working.
