Blue 2-1 dimmer binding Ikea Styrbar remote

I just recently got the Blue dimmer. Is it possible for me to bind an Ikea Styrbar which has LevelCtrl to dim/brighten the lights that are wired to the blue dimmer?

Sort of like binding the ikea styrbar with one of their dimmable zigbee light bulbs, but instead of a light bulb, it would be with the connected lights.

My setup is home assistant + zigbee2mqtt.

Binding with OnOff works, but holding the brightness buttons down doesn’t do anything.

FWIW, I’ve had a similar experience with those.

I find that if I bind to a fan module, then both on/off and dimming work as expected. But if I bind to a switch, only the on/off works.

Also, recent versions of their firmware have broken group binding. I’ve wanted to downgrade to older firmware to see if that fixes anything, but I haven’t tried yet.

2.4.16 - Only allows binding to a single device
2.4.5 - Allows binding to multiple individual devices, but not a group
1.0.024 - Allows group binding?
