I just moved my shades over to Hubitat, however I'm seeing this error when I go to Devices --> Shades --> Click On/Open. Any idea what might be wrong?

Edit: Additional info. I was able to get this to work by setting it up as a Dimmer. This allowed the shades to raise/lower by turning it "On" and "Off".

Now, I then tried to setup groups using the "Groups and Scenes" built in app. Unfortunately, creating a group only seems to only work for bulbs. It will setup the group, but it won't control them correctly. Can this feature be added?

Same issue for me too. I also tried the Group dimmer 2.0 and 2.1 with no luck

As a work around, I had to create a dashboard button for each shade. On, off, and level works this way.

I was thinking about trying a rule that when one moves it moves the other.
