      @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.

      @pavel.cernocky You have to define the variable as retain

      @tomas_hora OK, I see, that makes sense.
      Thanks a lot for your support.

      @sidoor It might work but it always depends on in what environment the installation is done. You can just cut the RS45 connectors and do the wiring in the standardized clamps

      We do not minimize the total length of the DQ line but we rather have a little longer (twice) total topology weight and minimize the distance of the stubs to achieve linear topology. So the length of the stub is about 1cm max.
