Hi,
I am using a few different Livarno/Lidl bulbs which have white/colour functionality, in this case it’s a Livarno Lux E14 candle RGB (HG06106B)
The bulb is being controlled via an separate PI running Z2M. The Z2M web interface controls colour fine, but the HA overview colour selector doesn’t do anything, unless you then choose an effect, in which case the selected colour kicks in.
But if you then change brightness, the bulb goes back to white mode.
EDIT: Just tried out another two bulbs, both Livarno Lux E27 bulb RGB (HG06106C), and one of them does respond correctly, while the other has the same issue as the HG06106B mentioned above.
EDIT 2: Sorry, I was confused it seems. The Z2M dashboard is behaving the same as HA overview and for the dud bulbs cannot control colour properly like HA. Therefore this is apparently a Z2M problem I guess.
Cheers,
James
