[Solved] Manually setting node-id does not work

  • Ok great!

    One more thing: I manually define Node ID´s like this:

    #define MY_NODE_ID 1

    But my serial gate way always receives ID 3 for this Node! Any idea why ??

    That sounds strange.. please post the log from your node.

    (I'm moving this to a separate topic)

    Using MySensors Library ver 2.0 on Gateway and Node

    @siod you have to set

    #define MY_NODE_ID 1


    #include <MySensors.h>

    That's it :)

    Nothing more to add, but Thank you! :bouquet:
