Temperature/Humidity device configuration

  • Hello!
    I need help with configuration of DataPoint:

    The device I'm using has 2 registers:

    • Temperature
    • Humidity

    I finnally found a configuration to retrieve humidity values:

    --> Modbus Serial --> New Data Point:
    Register Range: Holding Register
    Modbus Data Type: 8 Byte Unsigned Integer
    Offset: 0
    Bit: (disabled)
    Settable: Uncheked
    Multiplier: 0.1
    Additive: 0

    But I can't found a configuration to retrieve temperature. I tried too many combinations without success.

    Well, how do I configure the datapoint to retrieve different Holding Registers values?

    The device manual you can found here:

    Thank you!

  • Hi Marcelo,

    On the point setting there is a value called: Offset (0-based) this is where you put in the holding register for the value you want to read.

    I don't read Portuguese so I'm not sure of the registers you want to read but it looks like it is all on the list. I would also check to make sure it really is a 8 byte register. In the temperature and humidity devices I use it's always just 2 bytes.

    Hope this helps,

  • Joel,
    you're right!

    2 bytes works for me. Offset was'nt working because I was selecting 4 or 8 bytes.
    Now I got things working here.

    Thank you and best regards!
