I juste find another bug. after few minutes, I didn't recieve any update from my node (everything is ok on another tcp connection). I just see this message 22:28:07.641 [DEBUG] [al.protocol.ip.MySensorsIpConnection] - Bridge is connected, connection skipped After restarting OH2, everythings is ok for few minutes ...

Seems it's too complex for me ... Perhaps someone else. It could be fine for battery powered nodes.

Works fine with channel 120. No more lost packets.

A great resource to have when working with the ESP8266: http://neilkolban.com/tech/esp8266/

ok for my next xenebender batch I will buy NRF together. And now I confirm the problem with bad contact (with my finger it works fine !!!. I will directly solder NRF to sensebernder tomorrow. Strange, my solders seems to be fine and I made it all one mmore time but same problem. I will let the new sensbender online all the night. I will check tomorow my grafana input !
