reading MQTT.Light docs page, it is not very clear, but is there a way to have a single state topic, where end node notifies HA using JSON message about all information with single command?
Right now I have separate topics for each of the commands, like RGB state, brightness state, on/off state, rgbw state, temperature state, …
Then you see you can have alot of info in 1 topic. In this case: office/rgb1
So the 1 light entity would have everything including RBG in this 1 message.
I think I found the solution. In the discovery MQTT packet, I had to put schema: json type, and then I receive all commands on single topic and I can update the state with single MQTT message.
