Thank you skywatch for your answer. I am talking about RF 433MHz and i have succesfully decode and resend RF commands by connecting RF transmitter and receiver on arduino like this project here: http://www.libremechanics.com/?q=node/31 How can i combine these sketches to make a mysensor node which will be able to read and send the RF commands?

@badisensors I have this same issue and am struggling to find a consice answer to the question. Have you figured it out? I would love to see a bit more detail about the important naming and numbering protocals for Gateways, Nodes, Sensors, and their output values within the MySensors architecture. So far, I am not finding much and progress is slow when I simply need to try different iterations and make conclusions/adjustments.

@badisensors see the earlier answers here.

OK SOLVED! I reinstalled the last version of mysensors library and i uploaded again the sketch to arduino node and now i can see my light sensor! Thank you very much for your help. Best Regards
