@mbj I think I finally solved the GW problem (signing password too short!).
Now I'm starting to deal with OH2. I'm seeing this in the log:

I have one node sending temp & hum data (DHT11: child 0 hum, child 1 temp). OH2 wont autodiscover. Does this mean it must be added manually?
I hope there's an autodiscover if I'm going to build a network....
