@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 0_1569339863243_GW_pic2.png
check that the addresses stored in the GW and loaded from the neuron are the same 0_1569339910879_GW_pic.png
upload the latest FW 1.24 to the GW
loadand save the sensor to the channel multiple times
