MQTT documentation on commands

[Holmis]

I have many Shellys that I control via MQTT and Openhab. I can read status from RGBW plus pm, but I can not figure out the command topic. I have tried serveral attempts:  

Topic:
shellyplusrgbwpm-xxxxxxxxxxxx/command/light:0

Value:
on
true
false
off
{"turn":"on","brightness":"55"}
{"output":"on","brightness":"55"}
{"output":"true","brightness":"55"}

 

Can anyone please help me in the right direction? :)

If you use RPC commands with JSON, you will success most easy way.

Topic:

shellyplusrgbwpm-xxxxxxxxxxxx/rpc

Values are like

{"method":"PlusRGBWPM.SetConfig", "params":{"id":0,"turn":"on","brightness":55}}

I'm not all sure about syntax/what params are in use with RPC...but that's the direction
