I can't find a 3rd party app that groups blinds. I used to just control my blinds with the shades grouping app, but I just got a new blinds device (iBlinds v3) that allows recalling the blinds to a precise numerical value (not just open/close). The Shades group app does not pass along these values correctly, anything besides 100 causes the blinds to close completely.
Am I missing this somewhere? This seems like it should be a basic built in function.
