    Hello
    I need help, I’m trying to set a formula so that above a certain value it is displayed as zero. (Cnl%256)/100 and let’s assume it displays a value of 2.54, I would like the zero value to be displayed in scad above this value.

    Hello,
    Channel formula example,
    Cnl <= 10 ? Cnl : 0
    Condition ? expression1 : expression2

    The easiest way is because I’m a beginner. I have a formula (Cnl%256)/100 and it calculates correctly and the device throwing the value 2.55 is considered 0 or null(invalid) and I want to get such an entry when it enters such a value.

    Could you provide screenshots of the settings and error?

    Cnl != 255 ? (Cnl%256)/100 : doubleNaN

    2.55 isn’t that after dividing by 100?

    If the value from the device is 255, then you will receive --- well, or you still need to add status processing or perform it through status processing
