    Hello, how do you connect the DS18B20 sensors in series on the 1-Wire bus - do you solder a twisted pair to the sensor legs and go to the next one via some quick connectors? This is supposed to be the bus in the Grenton: 6 sensors connected to Analog In/Out.

    They are supposed to be in parallel not in series. They have different addresses, then communication goes on one line to all of them.

    >>21753039 >>21753039 How do we connect them? We enter the Wago we make a detachment for the sensor and from the Wago we fly on to the next one? We solder the wire to the feet ?

    From the comments that the transmission is digital I would only recommend soldering but as you described.

    >>21753080 And what do you think of the so called tri-field jellies, they take up less space, instead of Wago, I wonder how the durability is, will it be most solid to solder two DQ wires to each leg, and in the case of VDD, GND three and fly on?

    I have been struggling with these sensors for some time. First I connected on a board, described and everything was fine. Then I plugged in the installation on a dedicated wire and it also played, but after adding a new sensor one of the existing ones stopped giving a value. The sensors soldered in parallel, as the Grenton and sensor documentation stipulates, with a parasitic supply.
    Connecting more sensors caused it to stop reading values from the existing ones,
    but only some of them.
    In the end, I bought a 5 V power supply and will be reassembling this already on a (non) parasitic supply until it works, I used sensors from two different vendors, each declaring them to be original DALLAS, but this was not confirmed with the serial number. The sensors are supposed to measure floor temperature, so the dedicated Grenton ones are moderately suitable due to their not very airtight design.
