Heya, first of all thanks for adding this @Hykario :)
I noticed a bit of an issue tho, not sure if it's a firmware quirk or if the implementation is a bit off in Z2M.

When enabling the group switches at the bottom everything works fine as long as just one group is enabled at a time. However enabling 2 or more groups only sends an action to the lowest group being enabled.

As example, if group 2 and 4 are switched on and you press power it only sends a command to group 2, but not group 4. If group 2 is then switched off and only 4 is enabled it sends a command to group 4 just fine.

I agree with @EpicLPer. Only the lowest group is triggering the action. When multiple groups are selected the device receives an additional action unknown event in addition to the others.

Futthermore the refresh button is not working and also triggering an unknown action.

Would it be possible to also send events (for group 0) when no group is selected? This would increase the amount of programmable buttons. It could also be used for most commonly used stuff, because you would save one additional button press.

z2m: Received Zigbee message from 'LightRemote', type 'commandOn', cluster 'genOnOff', data '{}' from endpoint 2 with groupID 0
z2m: Received Zigbee message from 'LightRemote', type 'commandOn', cluster 'genOnOff', data '{}' from endpoint 3 with groupID 0
z2m: Received Zigbee message from 'LightRemote', type 'commandOn', cluster 'genOnOff', data '{}' from endpoint 4 with groupID 0

seems like the remote is actually sending data for every endpoint.
I will add this as soon as i got Time, hopefully this Weekend.

I think the Remote is not sending anything if none of the endpoints is selected. So your request is not possible @freeDom-

Thanks for your analysis! Sad that the manufacturer did not see the potential for another 14 programmable buttons :-D.

Maybe somebody can help me how can i get action_hue status into an entity? i have only a entity from the action?
