Remove ZHA binding does not work

Configuration

Hi!

I have an IKEA RODRET Dimmer included in my Zigbee network (ZHA) which works quite well. Today I added an Aqara Plug to the network, which also works well. BUT the dimmer does switch the plug even though it is not supposed to?!? I tried to delete the binding of the dimmer:

There was a green confirmation mark, but still the dimmer does switch the plug?!? What else can I do?

Thx a lot :slight_smile:

Did you wake up the dimmer (by pressing one of its buttons) before unbinding?

Also, IKEA and Aqara are known to interact with each other in various annoying ways, and not all of them can be fixed.

Yes, I woke up the dimmer and then tried to unbind it.
Does it help to switch to zigbee2mqtt? I don’t think so, because it seems to be direct communication between the dimmer and the plug.

Do you have a suggestion for a battery powered switch that works better?

Thx!

Yeah I’m not sure if z2m will be able to fix this :slightly_frowning_face:

Don’t really have any suggestions for a switch, I use IKEA myself but I don’t have any Aqara switches that they may interact with.

But in theory, it should be possible to delete this binding, right? So is it a bug or a feature? If it is a bug, is it a bug of ZHA or the Zigbee firmware of Aqara? Confusing…

Have a nice day!

I don’t think it’s a binding (in the Zigbee sense of the word) but an issue where the IKEA remotes, by default, broadcast to a particular Zigbee group and the Aqara devices, by default, listening to that group.

Sometimes it’s possible to remove the devices from that group to stop either the broadcasting or the listening, but not always.

It’s a bug-vs-feature debate whether devices should have such default behaviour, but I would call it a bug if you cannot disable it. Ultimately it’s an issue caused by the device firmware (IKEA and Aqara).

Yes, I agree! For me, it’s a bug, since now I can either use the plug or the dimmer.

How could I remove the device from the group? I do not have groups defined within ZHA.

I use z2m myself, so I don’t know how to do that in ZHA. But like I said, it might not even be possible to fix this issue :frowning:
