ZigBee network not responding to all button presses

[Hellis81]

I have the following visualisation:

The square is the conbee II stick.
The round things is my IKEA remotes.
And two of them are connected to the oval shaped which is a ZigBee inwall dimmer.

The distance between the Conbee and the dimmer is about 2 meters so it is closer to the remotes but one line is red, one is grey and one is orange, is that indication of an issue?
I don’t know how to read this visualisation.

Is there something I can do to bind them directly to the Conbee, if that helps.
I have tried:

And use unbind on the dimmer (taklampa) but that has not helped. Or is there something more that needs to be done?

With ZigBee I think you’ll find that your devices will connect how they want and there’s really not much you can do. Within ZHA, you do have an option to add a device to your coordinator but there’s no guarantee it will always stay that way.

Try that and see how you go.
