Here are my things for the Renovent:

Bridge modbus:serial:brink [ port="/dev/ttyUSB0", id=11, baud=9600, dataBits=8, parity="even", stopBits="1" ] {

    Bridge poller air [ start=4008, length=5, refresh=300000, type="holding" ] {
        Thing data holding4009 [ readStart="4008", readValueType="int16", readTransform="JS(divide10.js)" ] // temperature outdoors
        Thing data holding4010 [ readStart="4009", readValueType="int16", readTransform="JS(divide10.js)" ] // temperature dwelling
        Thing data holding4011 [ readStart="4010", readValueType="uint16" ]  // pressure supply 
        Thing data holding4012 [ readStart="4011", readValueType="uint16" ]  // pressure exhaust
    }
    Bridge poller actFlow [ start=4027, length=2, refresh=300000, type="holding" ] {
        Thing data holding4028 [ readStart="4027", readValueType="uint16" ]  // flowrate supply
        Thing data holding4029 [ readStart="4028", readValueType="uint16" ]  // flowrate exhaust
    }
    Bridge poller bypass [ start=4029, length=2, refresh=300000, type="holding" ] {
        Thing data holding4030 [ readStart="4029", readValueType="uint16" ]  // bypass position
        Thing data holding4031 [ readStart="4030", readValueType="uint16" ]  // bypass operation
    }
    Bridge poller preHeater [ start=4036, length=2, refresh=300000, type="holding" ] {
        Thing data holding4037 [ readStart="4036", readValueType="uint16" ]  //preheater status
        Thing data holding4038 [ readStart="4037", readValueType="uint16" ]  // preheater power %
    }
    Bridge poller maintenance [ start=4038, length=2, refresh=300000, type="holding" ] {
        Thing data holding4039 [ readStart="4038", readValueType="uint16" ]  // current fault code
        Thing data holding4040 [ readStart="4039", readValueType="uint16" ]  // error message filter
    }


	Thing data holding6001 [ writeStart="6000", writeValueType="int16", writeType="holding" ] // set flowrate
	Thing data holding6013 [ writeStart="6012", writeValueType="int16", writeType="holding" ] // set control mode
}

Hi Berndq, how did you generate this data? If I connect my Pi to the USB-RS485 device, how do I get this data for my Brink Renovent Excellent 300?

Also, tangential question: before connecting the USB-RS485 to the Brink, should I power off the Brink device?
