In our skill we added recently the RangeController for blinds. As long as a user controls the device directly the command "Set [device] to 50%" works just fine.
As soon as blinds are added to a group this command does not work anymore. A group with only blinds in it can't set the opening with the command "set [group] to 50%"
As we used the PercentageController this was not an issue.
Is this intended in some way?
