Full support for Xiaomi WRS-R02

Hi,

it seems for these Xiaomi switches command-mode is not quite working bug-free. It is not possible to bind the left and right switches to different groups / devices. It seems that the switch is always sending the click signal from the first endpoint.

It’s also noted in a todo from this PR #2621

// TODO/BUG:
// Did not understand how to separate the left and right keys in command mode -
// the "toggleCommand" always arrives from the first endpoint

When I researched this I came upon following comment in the deconz github. Would this be something that we are missing in the Z2M coordinator firmware right now? https://github.com/dresden-elektronik/deconz-rest-plugin/issues/4842#issuecomment-845438855

Apologies if I oversaw something there or it’s totally unrelated.

If I could provide anything else to debug this, I’ll be glad to do so.

I think this comment also talks about the same problem: https://github.com/dresden-elektronik/deconz-rest-plugin/issues/5104#issuecomment-882923413 unfortunately I’m not really knowledgeable in the zigbee space, so I’m no really understanding what they are talking about.

Same problem here, Does someone have a solution for binding the double rocker??

I have the same issue. Currently I unable to bind a double rocker switch (WRS-R02) to a double channel relay (LLKZMK11LM) to be able to control both channels separately.
