Hey All. Newbie alert here. I love the work you all do on here and this project is so exciting. I'm hooked after 2 weeks of 'fettling' and building sensors.

I've hit a brick wall though. after struggling with openhab1 I decided to make the leap straight to openhab2. Although in early days of testing it seems immediately abit more user friendly.

What I've done so far...
RaspberryPi3 is acting as controller with openhab2 installed and running fine. bindings to TV and Nest thermostat all working lovely.

Clone arduino Uno's with capacitors added for radio with NRF24 radio cards

Created GatewayW5100 gateway using the mysensors library sketch for it and set static IP to 192.168.0.11 (Openhab2 is set to 192.168.0.10) and my router gives DHCP from 192.168.0.20 up

created a temp and humidity sensor node and a node with a relay to turn a lamp on (both from mysensors library). Tested radio on all before moving ahead.

Installed the mysensors binding on OH2

Added a ethernet gateway

disabled startup connection check as it kept failing to initialise and showed as offline

Tried auto discovery of nodes... NOTHING

Tried setting node ID manually on the arduinos.. Still NOTHING, even if i add a thing manually to OH2.

I'm hoping i'm doing something stupid and its an easy fix.. Any pointers for a newbie??
