profile is above.
Most likely the "datatype": "float16", is not float only int16
You need to set "datatype": "uint8" where 1-byte for control is needed. Also don't use "datatype": "float16", use "datatype": "int16" with a multiplier set.
OK Thanks, the temperature values with float are coming in perfectly but i will change them with Int16 and test again. i will do the others with uint8 and test. Thanks
From 0 to 20.47 float16 is the same value as int16 / 100. Outside this range you will get invalid values. You can safely use float16 as bus_datatype though.
Thanks for the support. Solved it. Attached the revised json for the IDU
