      @martin-kudláček

      Thanks a lot, Martin! :-) I'll give it a chance.

    • pH and EC sensor

      Hi,

      Are there any pH and EC sensors that work with Neuron? Via the 1-Wire?

      Thanks in advance!

    • RE: Neuron L503 - Group 2 analog inputs

      @OlivierP, what type of pH and EC sensors do you use? Would you recommend some?

      Thanks in advance!

    • Max length of 1-Wire

      Hi,

      What's the max length of a cable connecting via 1-Wire? Would like to have a temperature sensor with ~ 30 meter cable (CAT5E, FTP, PE) connected to the 1-Wire Bus. Would that work?

      Thanks!

      @tomas_hora

      BTW, I absolute love Neuron! <3 I'll put it everywhere.

      Having a simple REST API is a bless.

      Thank you for all your hard work that goes into UniPi!

      @tomas_hora

      Thank a lot for your help!

      I end up using Raspbian and it works out of the box! :-) Minibian seems to be a bit buggy, wouldn't recommend.

      Thanks!

      Yes, I did. Still the same. :-(

      @tomas_hora, thanks for the reply!

      Here's the output when installing the Overlay again.

      Hi,

      What am I doing wrong? Could you please help me?
