  Hello @bibabutzemann, the 1-Wire pinout on our PLCs is documented here: https://kb.unipi.technology/en:automation:02-glossary:1wire-hidden Since your sensor is not original from UniPi (we have 4 wires), I can only guess the function of the wires: red: Vcc black: GND yellow: 1-Wire But you need to refer to the documentation of your sensor, or do the blind test which may damage your sensor. Best regards, Martin

  Hi Thomas, I've uploaded the driver here: https://github.com/marioverhaeg/UniPi AnalogueInputs and outputs are not implemented, but digitalinputs, onewire and relays are working. There are some events and some functions to poll information from the board. As said, I'm far from a professional developer but it might help others to understand how to read information from the UniPi. I will try to update the project now and then when I make improvements.
