Christoph,
You have to ‘reply’ to someone so we know what question you are answering (OR include enough information for us to just follow it smoothly)
So given your response : -
<template state cover.rollladen_gross_wohnzimmer=open; current_position=23, model_type=HmIP-BROLL, rssi_device=-60, rssi_peer=-61, id=3014F711A0001118A9A59B4D, is_group=False, friendly_name=Rollladen groß Wohnzimmer, icon=hass:window-shutter-alert, supported_features=15 @ 2020-06-24T08:30:24.022154+02:00>
I assume that this was ‘supposed’ to be for me ?
So you entity_id is : - cover.rollladen_gross_wohnzimmer
This is the first time you have properly stated that
Now All devices (from different manufactures, ‘may’) have different attributes and options, so this is why everyone was asking these questions
So given this and @pedrorferreira 's excellent guess, you know you need to set up a sensor based on : - “{{ state_attr(‘cover.rollladen_gross_wohnzimmer’, ‘current_position’) }}”
Do you know how to create a sensor ?
From your post and your pictures it looks like you only use the GUI so I can’t help you with that. But I’m sure someone else here can.
Once you have that you can set up a card to display it. You can have a slider (or just a ‘percentage open’ box (typically not ‘percentage closed’)) to control it.
@pedrorferreira - can you help him with that ?
(though you may not know the GUI that well either )
@Burningstone - I know the forum is supposed to be in English, but maybe you can PM him, explain normal forum rules/conventions, replies, tagging pasting code direct etc. (tall ask but your German is far better than … well pretty much ‘my anything’ ! )
I’m guessing ‘doppless’ counts as a ‘capital’ and therefore not allowed in entity_id’s ?
I’d help more but I don’t actually have any ‘covers’
