knx light control from mqtt cloud server

[toomoo]

Hello.

I bought old house and its installed knx lights. I don't know about knx. I search about knx logic machine connect mqtt. I found script. 

Then i tested https://openrb.com/mqtt-client/ this script send value to cloud server.

So can i control knx lights from my own mqtt cloud server? if it can please give me script and tutorial things. 

Sorry for my poor english.
