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?

Check this repo.
https://github.com/MadPatrick/Solaredge_modbustcp
It side repo so it will not interfere the original repo
I've included the meters and inverter also

I am totally lost here ... how exactly is this better?
I also intended to maintain my forks and the extra branch which allows for better support for "dimming" the production and batteries, but I can simply create a PR for Addie's version whenever he becomes active! I have worked with a few people on improvements, and then it all went silent.
So why create another separate version?

[madpatrick]

No offense to Addie's plugin and if you read carefully i'm also saying this.
Also it is not a new or another separate version, but an adjusted version for where i issued a PR
Only becauce there was no maintance over the last years i assumed my PR will not be issues in a reasonable time
For that reason i offered my Git location for the people who are interested in the adjested version

But... no worries. i've removed my previous posts and people can still use the old original plugin.
Next time when i update an old unmaintained plugin i'll keep it private

[MikeyMan]

The joys of open source.

Keep it cool guys, you're all doing your best. Much appreciated.

Hope we can find a way to get into regular maintenance.

I obviously missed some (?) discussion, resulting in Madpatricks repository not being usable anymore? The readme is empty.

Besides that I noticed the modbus library it depends (nmakel/solaredge_modbus) on is archived, in github not sure if this is going to be a problem in the future.

For now I will stick to Addieś 2.04 beta version

[imautohuttraeger]

Sigh!

As a simple user I am absolutely dependent on the - very much appreciated - work of guys who know their stuff. Please don't work against each other.

If you have a simple Solaredge setup (just solar panels), I would stick to Addieś plugin as described on the wiki (and propably in the first post of this thread).
If on the otherhand you use a battery and therefor also a meter, you better use the 2.04 version which you can download a a zip from Addie's tags part on github.

Not sure what happened here today.

Ah - thanks! Indeed I have a setup including a batterie.

I had this running a while ago on bullseye, but after the new domoticz release 2026 required a higher release, I had setup my Raspi from scratch using Trixie. But now the step-by-step instructions don't work anymore, as it now needs a phyton virtual environment (venv) for installation. Somehow I have even managed to install solaredge_modbus that way (don't ask me for details on how - it is too sophisticated for me). But in Domoticz, I get these errors:

Code: Select all

2026-06-23 12:48:47.775  Error: SolarEdge ModbusTCP 20260621: (SolarEdge_ModbusTCP) failed to load 'plugin.py'.
2026-06-23 12:48:47.777  Error: SolarEdge ModbusTCP 20260621: Traceback (most recent call last):
2026-06-23 12:48:47.777  Error: SolarEdge ModbusTCP 20260621:   File "/home/pi/domoticz/plugins/Solaredge_modbustcp/plugin.py", line 68, in <module>
2026-06-23 12:48:47.777  Error: SolarEdge ModbusTCP 20260621:     import solaredge_modbus
2026-06-23 12:48:47.777  Error: SolarEdge ModbusTCP 20260621: ModuleNotFoundError: No module named 'solaredge_modbus'

AI (Claude) tells me, that I either have to "break-system-packages" or that Domoticz should use the venv. I don't want to mess it all up, so I have stopped and hope that someone can give me an advice about how to further proceed.

Hi all,

I created this plugin almost six years ago, and for most of that time it has just worked for me. Over the years, people have asked for things like meter and battery support. That code is already in a separate GitHub branch, but I never got around to moving it into the main release.

In the meantime, Python and the packages used by the plugin have moved on. Because of that, some people may now run into installation or compatibility issues that were not there before.

The plugin depends on the solaredge_modbus package (https://github.com/nmakel/solaredge_modbus), which was archived by its developer earlier this year. That means it will not receive updates anymore.

So this feels like a good moment to look at what should happen with this plugin. If this plugin is still useful to people, it probably needs a more serious update. I would like to reduce the dependency on third-party packages where possible, move the meter and battery support into the main version, and improve the error handling and general maintainability.

I am willing to start working on that, but I need input and help from the community:

• Is this plugin still being used? I do not have any usage statistics, so it would be good to know if there is enough interest to make this worth the effort.

• Who can help with testing and debugging? There are many different hardware and software combinations, and I cannot test them all myself. I am especially looking for people who can help test the plugin and report issues clearly.

• Who can help support other users? Some people run into installation or usage questions. It would be great if a few community members could help answer those questions when they come up.

What do you think? Is this plugin still useful enough to justify a bigger update, and are there people willing to help with testing, debugging, or user support?

Thanks in advance for any feedback, and thanks to everyone who has used, tested, or contributed to the plugin so far.

Regards,

Addie Janssen

I am still using solaredge_modbustcp to monitor my solaredge ...

[Sjonnie2017]

Still using your plug-in but unable to support you with coding or otherwise. I do, however, can help with debugging/testing a new verson of the plug-in although I am a bit hesitant due to history

[imautohuttraeger]

[...] is this plugin still being used? [...

Great to read your post!

I am also using this (highly appreciated ) plugin and even the "meters" branch (named as pre-release for Version 2) is working almost stable.

This especially enabled me to get all data (including the batterie) into the energy dashboard page and the widget for the new dynamic dashboard

I really would love to help with testing, debugging, and user support. But as I am a non-coding-guy, I can only do it from a user's perspective.

I am also still using the plugin, the branch with the meter and battery support

@AddieJanssen,

I've used the extended version of Jos van der Zande , it works with solaredge, meters and batteries. I control the batteries and the charging directly and i must say it works fine, please contact Jos before you make any additions, see github! https://github.com/jvanderzande

greetings,

EDIT Jvdz: I removed my visible email

@AddieJanssen,

I have made several changes to your codebase and never bothered to make PR's as I (wrongly) had the impression you checked-out on this particular project.
My own interests were these 2 items (short version):
1. Be able to change the level of "Active power" from Domoticz with a Dimmer device. (Active in my master)
2. Add optional sync with an P1 device, so the SE device updates more-or-less happens at the same time as the P1 device. This is purely cosmetics for the Energy dashboard and nothing more.

This thread shows the whole story and many of the other changes made in the other branches.
Feel free to use what you want to update your github, and let me know when you like a PR for any of the first 2 listed functions.
As to the other branches, I guess I went a little overboard with changes there as I was (wrongly) under the assumption you abandoned this particular project, so pick and choose whatever logic you want to implement too as your current version had some issues for several folks and i tried to support them, but am not in a position to test any myself.

I am still using solaredge_modbustcp to monitor my solaredge ...

Ditto.. using the plugin every 10 seconds for years now..

Hi AddieJanssen,

I'm using the plugin since I got my Solar Installation in 2019 and my Raspberry on the P1 Meters in 2020 (at least Corona had one benefit, to get myself to domoticz ^^). When installing my Battery + Battery WR + Meter, I switched to the meters branch.

It survived the migration from raspbian on debian10 with python2.7, to debian bookworm 11 with python 3.9 and now it's still running on trixie 13.0 with python 3.13 on raspberry and inside dockers on synology

Code: Select all

pi@enerystation:/srv/domoticz/plugins $ pip3 list | grep modbus
pymodbus                     3.6.8
solaredge-modbus             0.8.0

For the Modbus, I'm running modbus-proxy 0.6.8 as relay between the SolarEdge and domoticz instances

and running fine

What are you planning to do, I did a lot of testing with jvdz, and i'm willing to be a tester for any new functionality, just let me know!
