Domoticz

Hi All,

I have been running in to issues with my domoticz setup. I have a Solaredge inverter and have used the solaredge modbus plugin by Addie Janssen. It all worked but due to an error the Raspberry upgraded and the installation was broken.

I was able to restore the system but I'm no longer able to get this plugin working. The combination Python requirements is not valid to run on Bookworm/Python 3.11.
I have been going back and forth with the help of chat GPT to get stuff running but in ends up the same.

Log:

Spoiler: show

I tried multiple versions of solaredge_modbus and pymodbus but found no working solution. Any tips?

Have a look here: viewtopic.php?t=43707

This version has the correct current requirements.txt and some extra options.

I am running the jvdz version on my docker/bookworm domoticz. Works fine here

May be install an older python version besides 3.11. Should be possible.

In my docker startup I have a lot of python lines to get the solaredge modbus running. The latest docker containers run on bookworm.

You do not need a "lot of python lines" in the startup bash file when you use the proper requirements.txt file as explained in the linked thread. One is sufficient as far as I know.
