Shelly Bulb via MQTT 2.4

Actually I’m not sure …

I’m a newbie to MQTT and have tried to adapt the syntax from Shelly1 as described here

The MQTT.fx topics collector delivers 2 topics:

shellies/shellybulb-3CC557/color/0
shellies/shellybulb-3CC557/color/0/status

that’s all.

I think the problem is that one need to transform the commands from openhab to MQTT.
There are some options in the channel configuration - but I don’t know how to do it …
