I’m trying to do the same thing. There are no smart bulbs in the fixture and I have two Blue dimmers installed. One dimmer controls load (mudroom solo), the other dimmer (mudroom) is only powered by line/neutral.
I attempted to set up my bindings as such but the powered only dimmer (mudroom) does not affect the primary dimmer (mudroom solo).
I’ve set up a group with the two dimmers. The powered only dimmer is still not working as expected. Do I also need to set up binding for the group?
nm. Got it. Set up the second switch binding to the group and it works now. I’ve got a few kinks to work out (like dimming function and LED bar synchronization) but I understand the relationship. Thank you.
