Guys, I have problem with GCHV modBus Gateway I have write the script however I can't write
can you please check it . ??

To get real holding register address subtract 40001 from the documented address. Set bus_datatype for On/Off to uint8 instead of float32.
RE: GCHV Modbus to LM5 - Samer - 24.11.2023
Sorry, I didn't get it Admin,
what do you meant by "subtract 40001 from the documented address"
RE: GCHV Modbus to LM5 - admin - 24.11.2023
If documented starting address is 40001 then in reality it is 0. All other registers addresses = ADDRESS - 40001.

Updated,
you can see the excel attached.
can you show me an example please ??
RE: GCHV Modbus to LM5 - admin - 24.11.2023
First indoor unit holding register addresses are 0 and 1, second - 2 and 3, and so on.

Should this works ??

Change all datatype entries to uint16, keep bus_datatype unchanged.
