New Python plugin: Domoticz SolarEdge_ModbusTCP

[MikeyMan]

So it seems i have a similar issue as above, however, i dont have domoticz in docker.

Log shows:

Code: Select all

Version is:

pi@raspberrypi:~ $ python3 --version
Python 3.9.2

What could this be?

Hi to all.

My SolarEdge Inverter went down, so I had a new inverter installed. After the installation, in Domoticz, I changed the hardware to a new IP address and a new port (1502) and activate the hardware in Domoticz. It is calling my inverter OK and receiving new data also.
However after the remplacement of the inverter, Domoticz shows the Total Energy now negative and the history now showing the data in a very small scale and negative as well.
My old inverter was SE3500H (2017) single phase, with text display. My new inverter is a SE3500H (2023) single phase, without a text display

How can I change this or

[Micha123]

It wil be Nice to trigger it not every some time, but an option to trigger it also on device IDX.

It wil be fine if it can be triggered on other device, like my P1 meter, then i have most actual data from my meter and SolarEdge inverter, i have also an dz script running it calculates the data what energy is now used.

But the plugin is working perfectly also with an older type of SolarEdge (with display) inverter. Thank you for that.

Until now im used the perl script to bring the data into domoticz. But your work is perfect.

I have just installed a new system with battery and metering and was wondering the result if I used modbus. Turned modbus on on the converter and installed the files.

In the first go I installed the Modbus TCP with github (git clone https://github.com/addiejanssen/domotic ... plugin.git) and ran sudo pip3 install -r requirements.txt

It all went well, but I wanted to use the battery and metering .....

I then used the 2.0.4. version, downloaded it to the PC and transferred the files (with PSFTP) to the proper directory with but only had failures. I deleted it all and left it but I am disappointed, what did I do wrong?

I keep getting the following errors:

I have version python 3.9.2 running with pip3 23.2.1

I'm fully stuck now ..........

[jawadde]

Perhaps try the discussions on the GitHub repository. https://github.com/addiejanssen/domotic ... iscussions

After Domoticz upgrade to 2026.1, the docker version, I cannot get the plugin to work, using:
pymodbus 3.6.9
pyserial 3.5
pyserial-asyncio 0.6
solaredge-modbus 0.8.0
Python 3.11

I 'm getting these errors:
2026-03-30 15:57:19.555 Error: SolarEdgeMODBUS: (SolarEdge_ModbusTCP) failed to load 'plugin.py'.

The import error ('Endian') is new to me. Checked the mentioned filenames and they all exist.
Tried older / newer pymodbus,, no help.
On the older Domoticz 2024.7 it works, even with pymodbus 3.7.3 and solaredge_modus 0.8.0

Noticed that domoticz 2026.1 (docker) is using pyhton 3.11 where 2024.7 is using 3.9.2

In Google searches (also AI mode) could not find a hint.
Example: https://www.claudiokuenzler.com/blog/15 ... an-upgrade

Any ideas?

tnx, nice to see that you are trying to do work on these python plugins ...
Seems addie is not very active lately ...

[MikeyMan]

Please forgive me my lack of knowledge on git... But is there a way to do an in place git pull to the new branch?

[imautohuttraeger]

A while ago, @jvdz made a fork due to the fact, that the owner of this plugin does not seem to actively work on this anymore:

viewtopic.php?t=43707

Besides other things, this fork also includes pure data from the battery (rather than a combined number solar + battery charging or discharging)

Is there any chance to get this also I to the basic plugin?

[MikeyMan]

Would be nice if @addiejanssen opened this up a bit for community development.

See : https://github.com/MadPatrick/Solaredge_modbustcp
i've maintain this until the orginal repo is maintained by addie again

Yes but can i keep my current install alive while switching to that repo?

[imautohuttraeger]

I've included the meters and inverter also

That's great. Will try it within the next days and would be very happy to have it working again.

Would it be possible to add the information about this to the list of plugins, so a user becomes aware of it in case she/he is not aware of this forum posting?

[imautohuttraeger]

As a dummy I am a little bit overstrained, so I need some help in order to correctly install the fork rather than the original:

So the starting point is
https://github.com/MadPatrick/domoticz- ... tcp-plugin

In the instructions, the following line is a copy from the original:
"Download the plugin zip-file from releases"

It leads to the original by @addiejammsen:
https://github.com/addiejanssen/domotic ... n/releases

Is my understanding correct, that I have to change the URL to the one of @MadPatrick?
https://github.com/MadPatrick/domoticz- ... n/releases
