Grouped covers with node red & knx

With lights and grouping them i have already tested →

  • a helper switch “central lights on/off”
  • and a node red flow for control this lights

But how to do this with cover / blinds?
a helper like a “switch” does not provide a arrow symbol for opening and closing

some input how to solve this would be great…thx

Have you tried to use a Template cover - Home Assistant ?
Or maybe just a HA group helper?
Or a button calling a KNX scene?

thx for your reply.

sure i tried button with knx scene but for some flexiblity reasons i dont want to mix knx scenes and automatition.

The group helper is pretty easy - thx for this hint.

Is there any advantage /disadvantage to the template cover - this seems a little more work.

thx.

The template cover could trigger a single common GA - sending only 1 Telegram. The group would send 1 telegram per group member.
Both should be perfectly fine.
