Hello,
I am trying to connect my Gree Versati IV heat pump with LogicMachine Reactor through Modbus. I can read the values of registers from Read Test button on modbus tab inside the interface of logicmachine. I would like some help to make the rest procedure to get these values on the knx bus.
Thank you.

RTU1
Device Address: 1
Function: Holding Register
Address: 13 (Water Tank Temperature)
Read Length: 1

It returns the correct answer.

[RTU 1 settings:
Port: /dev/RS485-1
Baud Rater: 9600
Parity: None
Half Duplex]

Select the datatype, it is most likely uint16

From Test button, I can read correctly the value.
I am trying to write in a correct way, the JSON file to import it as profile.

But in Read test you didn't select datatype and if you don't select it it is using int16 but documentations says uint16 so want to be sure before making you a template.
