Gree Versati IV heat pump - Modbus connection

[kyriakos@webros.gr]

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.

Please provide Modbus register table doc for your device.

Please provide Modbus register table doc for your device.

Thank you for the response.
I found the table in the following link:

Share the settings you used in Read test and which value was it.

Share the settings you used in Read test and which value was it.

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.

[Daniel]

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.

Try this, you have two examples.

I tried both int16 and uint16 and in both situations, I receive the correct value of temperature. I' ll try the JSON file you sent me.
Thank you for your support.

I made a progress!
I added also some more registers. I don' t know if I do it in the right way, but when I try to add an extra register, I have to delete the profile and do the whole process from the beginning and do the mapping from all of the entities. Is it the only way or I do something wrong?

Yes, you have to create device from scratch when updating the profile. To make things a bit easier you can set group addresses via bus_address field in each mapping entry. This way when creating a device registers will be mapped automatically. Example: https://forum.logicmachine.net/showthrea...6#pid35496

Adding the extra line with bus_address, make things easier! I would like to give me an extra help about getting the information of byte 2 / bit 20 (Heat+Hot Water Priority) where 0:Heat/1:Hot water 
[ from https://man.kievclimate.com/man/Gree/Ver...20V1.5.pdf ]. I tried a lot of different syntax formats, but no correct value.

Try setting type to "coil". Bit number is the coil address.

Thank you! with this setting I can map this entity in the bus.
