Repeater Node problem (with solution).
Using 0.0.3-final with mys 2.1.1 for the nodes and mys 2.2.0 for the gateway.
Problem is if you construct a repeater node using the examples code in the arduino ide it doesn't work. The reason is that the controller is trying to give it a node ID of 0, which is already taken by the MYC node.
The solution is to add #define MY_NODE_ID 180 before including mysensors in the sketch. 180 is just a number I chose, you can use any that are not already in use by that controller.
