Python Plugin: GoodWe solar inverter via SEMS API

[JanJaap]

Well you'd need to post some logging to see why it would cause the crash. There are multiple users without issues so maybe you missed some of the preconditions?

[whoami]

I see that since the 4th of january I get the message:

"Failed to request data: Failed to call GoodWe API (return code = 100007)"
rebooting or restarting wont help.

Does anybody has this same message?

EDIT: selected europe and it works again

[JanJaap]

I had the same issue, restarted the plugin and logged in with the Goodwe app and it worked again.....

Hi,

I'm trying to get this plugin running, but get this in the logs:

I'm running domoticz in a docker container on libreElec.

Python is installed, but maybe I'm missing some additional packages?
any idea?

thanks
regards,
Johan

[JanJaap]

Yes, you are missing the 'request' package as indicated in the log. Please see installation instructions. Be aware that the installation path may depend on the user that makes the instalaltion. Your logfile mentions the path below as to look for the requests package.

'/config/plugins/domoticz-GoodWeSEMS-master/:/usr/lib/python38.zip:/usr/lib/python3.8:/usr/lib/python3.8/lib-dynload:/usr/local/lib/python3.8/dist-packages:/usr/lib/python3/dist-packages:/usr/lib/python3.8/dist-packages'.

[jspeybro]

ok, got it to work by copying manually the required modules to the Goodwe plugin directory
in case someone else needs it for libreelec 10:
I had to get these libraries from here:

https://github.com/psf/requests
https://github.com/urllib3/urllib3
https://github.com/chardet/chardet
https://github.com/kjd/idna
https://github.com/certifi/python-certifi

I unpacked them and copied the subdirectory with the library name to
/storage/.kodi/userdata/addon_data/docker.linuxserver.domoticz/config/plugins/domoticz-GoodWeSEMS-master/

after that, the devices show up and can be added to domoticz.

thanks for the plugin.

any way you can also get it to download all the historic data?

[waltervl]

Perhaps consider to use a docker container on LibreElec:
https://www.domoticz.com/wiki/Docker

[jspeybro]

that's what I did, but then I didn't find how I should add the extra libraries that were required for python. just adding them manually to the plugin seemed to work for me but if there's a better way, I'm all ears.

[waltervl]

Other way is to install them within the docker container with

docker exec -it domoticz
And then in that shell
pip3 install "module"

You have to install them every time you upgrade the docker container. There is already an discussion to have some kind of script in the container to have them installed after update.

[waltervl]

There seems to be a Python library that is reading the Goodwe inverter directly. See https://domoticz.com/forum/viewtopic.ph ... 56#p285656

Is it possible to create a plugin for this? Should be better than scraping the cloud. Also when the cloud portal is gone (like Omnik) you can continue to monitor your inverter.

It seems that this libary is very usable for Domoticz: https://github.com/marcelblijleven/goodwe

Hello Everyone,
I;'d like to ask you, about compatility issues on Domoticz Version: 2021.1
After update I dont have field for password and plugin wont connect.
I tried to clear browser cache/incognito mode/ domoticz reinstall/ plugin reinstall... nothing works...

Im thinking to revert back to versio 2020.03.

Can you please advise
M

[JanJaap]

I'm running latest development with no issues.... Perhaps try a clean installation?

[tykasan]

Thank for suggestion. I was hoping for not having to do so...
But yes, it worked....

fortunately I had a copy of working backup (not the latest one) but it will save me a lot of time to cofigure

Thank you for your input!

Restarting Domoticz doesn't help, after 5-6 successful SEMS portal polls the plugin fails again with the same message "Call to function 'onMessage' failed":

Additionally, after restarting Domoticz and stopping the plugin, I've got another bunch of errors:

...

It has been working fine up until today.
Has something changed on the SEMS portal that needs updating the plugin?

Additional question: is it possible to make Domoticz keep running if one of its plugins fails?

[JanJaap]

You seem to be using the (very) old version by Dylian (which is no longer maintained). You need to pull from here:
https://github.com/JanJaapKo/domoticz-GoodWeSEMS

This one is running flawlessly on my end.

[JanJaap]

OK I need some more info to fully get it. Please run the plugin in debug mode and create an issue on GitHub with the logging included. Please also provide info like operating system etc.

Edit:
OK I see the previous comment is gone so assume the problem is also gone?

[Darsh]

Hi Jan-Jaap,
Thanks, your 2.0.7 is working fine. The issue was caused by the wrong portal password.


Darsh

[JanJaap]

OK, that is good to know. Wrong passwords should be handled a little bit more elegant than this I'l look into that.

[tonymer]

Hi, Thanks for the plugin. Would there be any way to have in Domoticz the import/export of energy to the network? For me it is the most important data because it is what allows me to activate things automatically without spending energy. That data is in SEMS and also when you connect locally through PV Master. I have done some local connection test with the goodwe inverter and I have managed to request some test information (Model, serial number, etc). Thanks in advance

[JanJaap]

Hi Tony,

What do you exactly mean with 'import/export' to the network? The inverter can only see how much power it generates into the network of your house (which is the main counter in the plugin). It cannot know how much you (your house) had to take from the public network (a.k.a the grid). You need to read out your connection (I've got a smart meter with a so-called P1 plug which nicely lets me do that in Domoticz). I also do not see any such data in the SEMS portal.

Things get a bit more interesting when you have an inverter with not only solar panels but also a battery. I do not own such a thing so I'm depending on others to provide me with the data structures to make that happen. See plugin issue 14. I do not have proper logging yet in that issue......
