Thank you @mfalkvidd! I have been busy and had many issues to figure out for myself, but I still can't understand how binding with openHAB works. How does the information from nRF24 get to openHAB? I have MySensors Binding add-on installed in openHAB. I would be very grateful if someone could help with this last step. After this my first little sensor will be ready to go live.

Hi @raulp, welcome to the MySensors community. I don't understand what you are trying to do, but the MySensors getting started guide is available from the rocket icon at the top of the forum (https://www.mysensors.org/about ) Developer contribution guidelines are available at https://www.mysensors.org/download/contributing Library documentation is available at https://www.mysensors.org/apidocs/index.html
