      @zorro_66 Any possibility to change the UTP to STP/FTP from the cabinet at least to the nearest hub?

      Btw. nice installation :) Would be great if you could share with us a few lines describing the project and a few picture.

          did not help with shielded cable

                  Now it has worked in two days
                  My second Unipi do not have these problems
                  where I have 20 pieces of sensors connected in a star network with no shielded cable.
                  Does it help to update the software in Rpi.
                  There seems to be some software errors.
                  Just got home 2 1-Wire hub from Unipi.
                  Can i connect with a standard RJ45 patch cable

                      My 1-wire is incredibly unstable
                      network dies at irregular intervals, showing unreasonable temperatures.
                      I have rebuilt my net for spec from Unipi wiki shielded cat5 cable and hubs.
                      But no difference 1-wire network die anyways.
                      So it can not be anything wrong with the network itself, but the fault must be in Unipi alt. software.
                      Grateful for help .

                        @zorro_66 Can you try enabling the CRC check at the sensors? Just check the box in the sesors in the Scratchpad group. You might need to make the sensor as a custom and backup your project before playing with it

                                Problem solved, I finally found a bad solder
                                at the VCC pin caused power loss in my 1-wire network

                                  We are sorry for that @zorro_66!

                                  But it is really hard to find out this kind of issue during our test but we will update our testing procedures... Thanks for the info.
