@kalophain if 1wire sensor is loaded to the channel, it's ID is stored in the non-volatile memory and so it should be restored upon boot of the gateway. Since the memory is tested on every piece, the probability that it no ok is really low. The DIP switch is used for firmware change and has no affect to the store/load of the sensors. Please make sure that: the baudreate in Neuron and GW is the same check that the addresses stored in the GW and loaded from the neuron are the same upload the latest FW 1.24 to the GW loadand save the sensor to the channel multiple times

Hi @kalophain, that looks like you haven't "Attach the controller". Try following this tutorial: https://kb.unipi.technology/en:sw:01-mervis:creating-new-project-hidden#attaching_to_the_controller Best regards, Martin
