@AVsetula I'm aware of this guide and about the OW_off_1 switch. The problem is, that it does not solve the problem in my case.
As I wrote before I tried to set OW_off_1 to true and then back to false, but all the temperature sensors kept showing 0 ˚C.
I haven't found any software way how to "restart" the 1W to working state. The only thing which works is restarting whole Neuron by cutting off the power.
If you have any other ideas, I'll appreciate them.
