@jkandasa Hi, thanks for your quick answer! Ihave uploaded on my Test-ESP8266 a firmware which comes with ESP Easy Mega Tool, because it's very easy to handle it. So i have no special firmware uploaded through Arduino IDE (this what you meant?).
Today i found on the serverlog this interesting entry (many of them):

2019-02-04 15:11:46,100 ERROR [Thread-6] [org.mycontroller.standalone.provider.mc.McProviderBridge:64] Unable to process this rawMessage:RawMessage(gatewayId=1, data=13.90, subData=out_esp, isTxMessage=false, networkType=MY_CONTROLLER, timestamp=1549289506089)

Looks like that humidty value was sent from ESP but the message format seems to be wrong ....

Hi to all,

i'm absolutely newbie at this forum. Today i have installed MyController on Raspi for my first time - easy and works great
Then i started to connect my NodeMCU & DHT22 to MyController. At this point no chance to understand how MyController works ... is there anywhere a userfriendly documentation to understand Gateway / Node / Ssonsor and how it works togehter? For e.g. when i install a Node (my fine working NodeMCU) i don't know what EUI is ...
So it looks now:

My ESP8266 is configured with ESP Easy Tool and works (show humidty and temp). On ESP i choosed Openhab MQTT.

Hope someone can help or have any idea.
Thanks in advance

Mark
