Failed to load 'plugin.py

[piacco]

Hi Addie,

I'have installed the plugin, but get an error, do you have a solution for this?

`Error: SolarEdge ModbusTCP: (SolarEdge_ModbusTCP) failed to load 'plugin.py',
Python Path used was '/home/pi/domoticz/plugins/domoticz-solaredge-modbustcp-plugin/:/usr/lib/python39.zip:/usr/lib/python3.9:/usr/lib/python3.9/lib-dynload:/usr/local/lib/python3.9/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3.9/dist-packages'.

Error: SolarEdge ModbusTCP: Traceback (most recent call last):

Error: SolarEdge ModbusTCP: from pymodbus.client.sync import ModbusTcpClient
Error: SolarEdge ModbusTCP: ModuleNotFoundError: No module named 'pymodbus.client.sync'`

I'm using Domoticz version 2023.1 and the python version is: Python Version: 3.9.2

It means that the plugin can not find one of the libraries that solaredge_modbus requires to communicate with the inverter.
Which version of solaredge_modbus did you install and how did you install it?

Hallo Addie, Bedankt voor jou reactie. Ik heb de plugin geïnstalleerd volgens de Domoticz wiki pagina. #enter domoticz plugins directory cd domoticz/plugins #if git command is not installed, install it with apt install git git clone https://github.com/addiejanssen/domoticz-solaredge-modbustcp-plugin.git cd domoticz-solaredge-modbustcp-plugin sudo pip3 install -r requirements.txt #restart domoticz sudo service domoticz.sh restart Heb ook even op mijn andere raspberry de plugin geïnstalleerd en dat gaat probleemloos. De rpi waar de plugin wel goed op draait daarop heb ik buster met Python versie 3.7.3 geïnstalleerd en op de andere rpi draait op bullseye met Python versie 3.9.2. Op beide rpi’s heb ik Domoticz 2023.1 geïnstalleerd. Heb met pip3 install solaredge_modbus de bibliotheek geïnstalleerd. Kan het ook liggen aan de Python versie in combinatie met Domoticz?

Did you install that library as documented in the README file? — Reply to this email directly, view it on GitHub<#60 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/ALLFND7SBIWV4VFLG6KBRBDW2HU6ZANCNFSM6AAAAAAVNKYH5U>.

I just installed the plugin and also got the plugin.py error.
Could not find the new devices.
This fix (from: https://www.domoticz.com/forum/viewtopic.php?p=272142#p272142) worked for me

sudo pip3 uninstall pymodbus
sudo pip3 install pymodbus==2.4.0

Then restart domoticz ( sudo service domoticz.sh restart )
