group light not mixing colours properly.

[tomtom13]

What happened?

I've switched from HASS light groups to Z2M light groups. Most scenes that I use, send a fixed colour and level to the group, but a few special ones do send different colour to different bulbs to make sort of mood scene - all that works good. However, reporting back to MQTT seem to report group colour and light level on random bulb from the group, rather than computing a median colour and light level. Please note that this happens with my SLZB-06, however before I used sonoff ZBdongle-P with same results.

What did you expect to happen?

I would expect the reported light level to be computed as a median, and colour to be computed as a median of croma key.

How to reproduce it (minimal and precise)

Create a group with 6 - 20 (in my case) philips hue light bulbs, set those to individual colours and observe reported by Z2M colours.

I might add that this yields additional problem: IF some of the light did not fully switch to their destination colour / light level - HASS will NOT attempt to resend the change request, because it's unaware that things wen't wrong ... after all it has a proper value from just one bulb in the group stating that everything is a OK.
