Thank you very much for this quick reply!

I read a thread with gw.XXX commands. That confused me. API say only #define MY_REPEATER_FEATURE.

Now it's more clear to me!

I do this via Pimatic and Raspberry Pi 3

I'm not sure whats happened... But i think its working now. I try to investigate why it works now! If i find the reason i will post here. Thanks for help.
