Python plugin: Modbus RTU / ASCII / TCP/IP Topic is solved

[Copitano]

Hi All,
I rewrote the script of the Read plugin and it reads the modbus RTU and modbus TCP/IP registers correctly.
I have no way to check modbus RTU over IP.
Just replace the plugin.py file in the location .../domoticz/plugins/modbus-read and restart Domoticz
I will work on the plugin for writing next week.
Dependences needed:
pip3 install -U pymodbus pymodbusTCP
pip install pyserial



P.S. I'm not able to attach file here so I left it on https://easyupload.io/fj9psi

I am very curious if you managed to rewrite the complete plugin for the new domoticz version.

It seems someone fixed the plugin for newer pymodbus modules https://github.com/DomoticX/domoticz-modbus/pull/42

Fixes allowing plugin to work with newer pymodbus version.
Some small improvements.
Tested on fresh Domoticz 2024.7 , Python 3.11.2 , pymodbus v3.6.9 with TCP modbus mode.
