SolarEdge via LAN interface

[rogerthn]

I did try SolarEdge_ModbusTCP on bookworm with no luck
I ended up using pymodbus-2.4.0, pyserial-3.4 and solaredge_modbus-0.6.5 that I did have running on buster.
On bookworm as normal user

Code: Select all

mv /home/USER/.local/lib/python3.11/site-packages/* /home/USER/SAVED_site-packages/

Please let me know if I should try to upload the tarball
Good luck

This is how I got the modbus connection working, in buster.

Code: Select all

pip3 install modbus==0.8.0
pip3 uninstall pymodbus
pip3 install pymodbus==3.6.9

The code used runs in my customstartup.sh I use in docker.

The problem for me is more computing the correct value for raw sun production, escpecially when using a battery and ev-charger. There is actually no value in the modbus registers for the raw sun production. But I am getting there and may be I will take the occasional miscalculculation for granted.

Hi Guys,

I have found this plugin which works with my Soleradge (and also of JvdZ)

https://github.com/addiejanssen/domotic ... tcp-plugin

This is how i got it to work

Code: Select all

git clone https://github.com/addiejanssen/domoticz-solaredge-modbustcp-plugin

Code: Select all

pip3 install -r requirements.txt

Code: Select all

pip3 uninstall pymodbus

Code: Select all

pip3 install -U pymodbus==2.5.3

Restart your domoticz and check your devices



Maybe somebody know how to use the latest version of pymodbus instead of downgrading ?
Using the latetst version give the following error

Code: Select all

No module named 'pymodbus.client.sync'

It works here with pymodbus 3.6.9 as is in my previous post.

[jvdz]

It works here with pymodbus 3.6.9 as is in my previous post.

That indeed works too! Thanks for sharing.

EDIT: When you update requirements.txt in the plugin directory to:

Code: Select all

pymodbus==3.6.9
solaredge_modbus==0.8.0

and then run : sudo pip3 install -r /home/pi/domoticz/plugins/SolarEdge/requirements.txt
It will also be fine as the newer version of pymodbus is uninstalled in favor of 3.6.9
