1-Wire problem, cant figure it out.



  • I got 2 temp sensors connected to a Neuron M203. i soldered an ethernet port to the 2 sensors and when i use a short UTP cable of just 20cm between the Neuron and the sensors it works fine. as soon as i put a 2 meter or 10 meter cable between it, it stops working. any thoughts guys?

    Hi @Nico!

    That looks like it's most likely a physical layer issue. I would check the solder joints as well as check for any possible shorts of breaks in the cable due to bending. The 1Wire should be able to go out several times further than 10 meters; perhaps try using a CAT5 cable or similar for added overall shielding.
