@codergirl56 Reading your question, I think your starting point is to have a look at the pingpong example (see below for the direct link) which comes with the mysensors library and try to modify it such that it starts sending the RFID data. direct link to pingpong example First you'd need to install the mysensors library of course, see the download page. How to do that is in the "Getting Started" as mentioned by @AWI. Just start reading and you'll be guided to it. good luck Boozz

@Ispandy, let resume some things because I'm lost You copied the sketch code from node 3 (= correctly running node with cardscans and remote control from openhab) to node 50 and you adapted the node id. This same sketch on node 50 is running correctly with cardscans but not with openhab? Correct? If above is correct: somewhere your openhab configuration for this node 50 is not correct. You say that node 50 is never receiving the openhab command, so there is a problem with your openhab configuration for node 50.
