Modbus - joaodaniel.pereira - 18.07.2024
Hi,
1. I have a suggestion, if we change 1 modbus profile, I need to remote everything related with modbus to update.. is't possible to create a automatic profile refresh or something ?
2. I have one device that send temperature with UINT16 -> 333 ... this it 33.3ºC ... How can I convert the value to have 33.3 ºC in knx?
Example:
the value in the bus is 333 (33.3ºC)
{ "name": "Temperature AQS", "bus_datatype": "int16", "datatype": "int16", "type": "inputregister", "address": 1, "writable": false, "value_multiplier": 0.1, "units": "°C" }
return 33 ºC why ? I convert the value to 33.3 but in the display is an integer value and ignore the decimal part... I dont have any "float" with 1 byte.. to show the correct value..
If I try to multiply with 10, I get 3330 ... but this is not a 2Bytes value to convert to 9.0001..
any solution ?

Change bus_datatype to float16

And the value for datatype ?

datatype should stays as is - int16

Thanks, Fixed.
Here:
https://kb.logicmachine.net/misc/modbus-profile/#bus_address
bus_datatype is not clear..
"
bus_datatype
Mapped object data type, key from dt table string/number, required
Example: uint8, scale or float32
"
what datatypes support ?
