@ricorico94 From the NRF24 datasheet: [image: 1518649573838-screen-shot-2018-02-15-at-00.05.12-resized.png] https://www.sparkfun.com/datasheets/Components/SMD/nRF24L01Pluss_Preliminary_Product_Specification_v1_0.pdf So, you should probably choose address a bit careful. To change base address just add a define in your sketch like this (before including MySensors.h): #define MY_RF24_BASE_RADIO_ID 0x00,0xFC,0xE1,0xA8,0xA8
