New Python plugin: Domoticz SolarEdge_ModbusTCP

[Sjonnie2017]

Thanks Eddie!

It does seem impossible to do it yourself, even with the display

I just contacted the supplier to "pump up the pressure" a bit

Greetz,

Sjonnie

[eddieb]

according to https://community.home-assistant.io/t/c ... /165625/29 it should be possible

[Sjonnie2017]

Thanks again Eddie,

Will have a look at it tomorrow. I'll see if I can figure it out and have the stomach for it

Greetz,

Sjonnie

[Sjonnie2017]

Well... the company that installed the panels sent a specialist over today. He enabled modbus_tcp in a matter of minutes. As a result I have a sh1tload of devices presenting me with information about the inner working of the converter.

Happy camper

Nice to read, that is how it should be !
welcome to the club

[Sjonnie2017]

Well, since I am in the club now... do I get a pin or a badge or a sticker?

Seriously though: It is nice to see the data stored in the converter and being able to display it on my Dashticz dashboard. I am thinking graphs and dials as we speak

Greetz,

First Thank you for the plugin it works very good except for:

is there a solution for this?

thanks to @StasDemydiuk this plugin is now added to the python plugins manager !

great work and thanks

Having some trouble getting the plugin to work after I migrated my Domoticz installation to a new Pi. I installed Domoticz and all required plugins on the new Pi and restored the database of the old Pi. Easypeasy (I thought). Everything seems to work; my DeCONZ plugin and my HomeWizard plugin all are responding. Youless works without a glitch.

But I cannot get the modbus plugin to work. It installed OK and the hardware is created but the plugin won't connect to my inverter. I removed the hardware in Domoticz and recreated it. As a result all devices are removed (Yay! ) but still no connection to the inverter. IP and port of the inverter are unchanged.

A part of the log filtered for the modbus plugin:

Anyone any idea?

Did you read the first-time install instructions on https://github.com/addiejanssen/domotic ... tcp-plugin ?

Go to the plugin folder and install all required addons:

cd domoticz/plugins/domoticz-solaredge-modbustcp-plugin
sudo pip3 install -r requirements.txt

...

Go to the plugin folder and install all required addons:

cd domoticz/plugins/domoticz-solaredge-modbustcp-plugin
sudo pip3 install -r requirements.txt

...

Well I installed as per the instructions. But I can try to re-install. (Sjonnie is re-installing plugin). This is the output:

Code: Select all

~/domoticz/plugins/domoticz-solaredge-modbustcp-plugin $ sudo pip3 install -r requirements.txt

All seems to be satisfied Unfortunately even after recreating the hardware the devices don't show up. It seems unable to connect to the inverter.

EDIT: Restarted Domoticz but that didn't change much :s

[JakeOfOz]

I have the same issue. I have a SE10K inverter, recently installed (march 2021).
As Sjonnie2017, I installed the plugin per the instructions, but get the same in the logging:

Code: Select all

2021-03-31 09:54:51.017 (Omvormer) Processing 'onHeartbeatCallback' message
2021-03-31 09:54:51.017 (Omvormer) Calling message handler 'onHeartbeat'.

I enabled the Modbus TCP port on the inverter (took a while without the installer, but figured it out). The port should be 1502, but it does not want to connect. Any suggestions?
Could it be that the inverter itself needs to be restarted in any way? (I would have no idea how that would be achieved though..)

[waltervl]

Perhaps you can debug with the base python library this plugin is based on https://github.com/nmakel/solaredge_modbus

Download the example.py from the link below and run it in a terminal window with your parameters:
example.py [-h] [--timeout TIMEOUT] [--unit UNIT] [--json] host port

https://github.com/nmakel/solaredge_mod ... example.py

[waltervl]

And there is also the following issue on github https://github.com/addiejanssen/domotic ... n/issues/9

Looks like PyModbus has been updated and the plugin is not handling this yet.
The solaredge_modbus library is also updated to 0.6.5 (plugin uses 0.6.2) so there could be some library dependency issues....

[JakeOfOz]

Ah, a temporary solution is this,
Run on your pi:

sudo pip3 uninstall pymodbus
sudo pip3 install pymodbus==2.4.0

Then restart domoticz ( sudo service domoticz.sh restart )
It works now!

[Sjonnie2017]

Indeed! It works. All devices reappeared without a glitch. Let's hope Addie updates the plugin to work with the new library.

[Zenek1961]

Hello
I have the same problem,
I installed the plugin from the first post and it does not find devices

Hello
I have the same problem,
I installed the plugin from the first post and it does not find devices *snip*

You are giving us little to work on but have you tried the temporary fix from @JakeOfOZ? It works wonders on a Pi so give it a try

[Zenek1961]

Yes I have 2.4.0

[Sjonnie2017]

OK, that's something to work on. You are on a Pi if I interpret the log correctly. Have you checked the IP of your inverter? Have you tried to remove the plugin, reboot Domoticz and add the hardware again?
