@user2684 Yes, that is the solution. Thanks a lot!

@vikasjee glady but I follow some one else steps lol https://bbs.nextthing.co/t/domoticz-small-how-to/2585 But instead of wget http://domoticz.sourceforge.net/beta/domoticz_linux_armv7l.tgz Just use Wget https://releases.domoticz.com/releases/beta/domoticz_linux_armv7l.tgz

Thanks for help. I installed 1.5.4 and reprogrammed the MQQTgateway and Dimmablelight and now its working perfect.
