            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.
