Multiple roller shutter custom position

Hi everybody, I’m a newbie coming from domoticz, I’ve a problem with roller shutter custom position, basically my shutters stay close from 80% to 88% (It depends they are not all the same), over that they collapse and open like a venetian. So if I want to stay in the dark and not wake up at dawn I must use the custom position. I discovered mushroom cover card and with one tap/service calling I can set a custom position and “close” a single shutter. So what’s the best way to rule them all at the same time? Groups can fully close or fully open but I can’t set a custom position for each entity in the group, so back on mushroom cover , Is It possibile to use call service multiple times with different entities each one with a different custom cover position? or any other suggestion to solve the problem? The following code is the one I use to control a single shutter position

    tap_action:
      action: call-service
      service: cover.set_cover_position
      target:
        entity_id: cover.roller_shutter_xxx
      data:
        position: 13

I would (and do) use a custom cover template entity and roll your own based on the values you need - then you can set them up to open to whatever position you want.

For me, I use homekit so I can open/close/open to a position all my curtains at once via voice, but if I had to do it in HA I would create another template entity for “all curtains” that calls the commands on each of the other curtains you have.

I took your suggestion and it give me a hint, I created an automation triggered by qr scan but everything will do I used qr since it does not interfere with anything, in automation I can use many actions , one for each roller shutter, so I can customize each one of them. Than in mushroom cover I’ve assigned to double-tap, call service, trigger automation. Not the cleanest way but it works like a charm.
