    This is what i’ve come up with so far. I have no idea but i think this should result something.
    What i don’t know if is my sensor is correctly wired. I did order a USB-RS485 dongle to check if it really
    works at all. Hope someone can confirm if the code below should come up with a result.

    The address of the sensor is 1 , that’s for sure, the input register for temperature is also 1, so..
