Python Plugin: GoodWe solar inverter via SEMS API

[MikeyMan]

I'm getting the same error now:

Code: Select all

Goodwe SEMS: TokenRequestException: HTTPSConnectionPool(host='www.semsportal.com', port=443): Read timed out. (read timeout=10)

Any known issues?

[JanJaap]

The read time outs in general are a known issue, see the Github page. The server did not respond for a configurable (which I set to 10 seconds) amount of time. I made the plugin such that it will retry 3 times and if it did not succeed, then it will throw an error like 'too many retries'. After which it will try again at the next polling interval. So nothing to worry about. And nothing I can fix either.

[MikeyMan]

Ok, no worries... In general it's working fine!

[JanJaap]

I'll check it our ASAP. Can you create an issue in Github and add log file with debug logging enabled? Probably the information received from SEMS Portal does not fit the expected format anymore

Hi JanJaap,

Installed your latest (V4) plugin on Domoticz 2023 running in Docker. Hardware created without error, but no Devices appear.
Looking at the log the message is: Error: Zonnepanelen: KeyError: '95000.........9'
Any idea what I am doing wrong? The key is correct and I can log in to the portal and get data with the username/password/ID
Thanks, Erwin

Why is it when i install the Goodwe sems api pugin an other plugin (CRONBEE) is not working anymore and this plugin complains that there is no requests library ? and i should pip install or pip3 install requests again. (this gives an error also)
When i deinstall the SEMS API plugin the other one is working again.

[JanJaap]

@erpi, did you follow the upgrade instructions to exchange the old key with the serial number of the inverter? Please post some loglines....

@provedance it is hard to say. Normally, these plugins are quite well separated from each other by the plugin framework. Normally, also the dependencies (the libraries you have to install) should not bite each other. Also for you: hard to say anything without logging. Btw normally it is pip3 install.

Hallo,

I'am a new user to Domoticz and the whole Pi scene. I managed to put up a pi with Domoticz and Zigbee2MQTT.
Now i'm trying to add my Goodwe 2500-ns to Domoticz. I've installed your plugin and get the following errors;

Can you tell me what this means or what i'm doing wrong?

[JanJaap]

it is a bit hard to say like this, I'd need some more logging.

Questions:
1) do you recognize the serial number 12500NSU15300047 from your SEMS portal?
2) when looking in th devices page of domoticz, are there any devices created for your solar panels?

[Zeil]

1. Serial number is the right one.
2. There are no devices are visible

some other logs..

[JanJaap]

could you switch debug logging on and look for relevant statements in the mentioned logfile (you might need to change ownership with sudo chown if you want to download it)

[Zeil]

Thanks for putting time and energy in my problem. (Noob mode activated) Can you tell me how i switch debug mode on? And do the rest you mentioned!

[waltervl]

See in your screenshot a few posts back the bottom parameter:
Log Level: Normaal
This can be switched to Debug.

[Zeil]

I've switched the the log level from normal to debug. Where can i find this debug?

[waltervl]

In your normal Domoticz log (menu setup - log) you find now more logging regarding this plugin.

You also have to press on update after you have changed the value.

[Zeil]

This is what the log spits out

@erpi, did you follow the upgrade instructions to exchange the old key with the serial number of the inverter? Please post some loglines....

JanJaap, My errors are EXACTLY the same as @Zeil posted. From my debugging, it seems the plugin breaks because of the new format that Domoticz expects for JSON commands (which seem to result from the python code). CreateDevices uses Devices call which must be GetDevices now...

Answer to your question: It was a fresh install so no database upgrade needed.

[JanJaap]

Hey,

I pushed a change a couple of days ago, this should fix it (Apparently I never properly tested a clean install). I think it should work now. I just struggle because I apparently messed up the database, therefore cannot test anything new until I solved that.......

Btw logging is placed in separate log file in the Domoticz directory on your RPi. The name of the file is displayed in the domoticz logging, it is a combination of the plugin name (goodwe) and the name you gave the hardware (probably zonnepanelen) so would be "goodwe zonnepanelen.log"

Hi JanJaap, with the latest code it works for me.
Thanks!

Did a git pull., and now under devices i see 18 hardware entries from my Goodwe inverter. At the moment it's dark outside, so no numbers to be seen. Will check again if the sun shows up.

I can find my "Goodwe zonnepanelen.log in my Domoticz directory on my Raspi. Tried to copy the file to my windows pc with SSH/Putty. No success yet.
Is there a way to see the log file through SSH? what's the command for that? And is there a way to give the user on a pi "admin" control?
