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?

@Avatar6740 I was able to get this working.

Using Z2M 2.1.0, I followed the these instructions, which allowed me to downgrade the Styrbar firmware to v1.0.024: https://www.zigbee2mqtt.io/guide/usage/ota_updates.html#local-ota-index-and-firmware-files.

A link to the firmware file can be found in this post: https://github.com/Koenkk/zigbee2mqtt/discussions/23243#discussioncomment-10038494

Once that was done, I created a group consisting of endpoints 1 from a VZM36 fan module and a VZM31-SN dimmer. I bound the Styrbar to that group (OnOff & LevelCtrl).

This resulted in the Styrbar being able to control on/off and dim level of both the light attached to the fan module and the LED strip on the dimmer.

Hope that helps.
