Python Plugin: GoodWe solar inverter via SEMS API

[vinjon]

it' sworking now, but only for one inverter (i have two in one powerstation)

Hetzelfde bij mij Ik heb maar 1 inverter dus ga voorlopig de errors in de log gewoon negeren

OK well at least it's working. I'll have a look after my holiday. To get this properly fixed, I do need the complete response of the second call to the Goodwe API, which is too big to fit into the Domoticz loglines (it'll be truncated). This can be retrieved using Postman. If you can send me these response then I can fix it (when I return from holiday....).

OK, this morning my plugin failed too. I updated and put the Plant ID in the mandatory fiel but get errors.
I updated python requests (nothing to update...)

The plugin is failing since 17-8-2021.
Already pulled the latest plugin and filled in my serial number, but still no readings.

SOLVED!
I had to do an upgrade of python urllib3:

Can you help?

Thanks

[waltervl]

Jan Jaap is on holiday so it will take some time to resolve the remaing issues....

[HansOtten]

For those like me not knowing what "Power station ID' is,

- login via a web browser to semsportal.com
- look at the url when the portal is running, something like:

https://www.semsportal.com/powerstation ... /XXXX-xxxx

- the station ID is the number part after powerstatussnmin/ a long numbr

Fill that in in the hardware and things start working, some real info yet, still errors on the log.
So i disabled the plugin waiting for the end of the well deserved vacation of Jan Jaap!

All,

I see the errors occur as well when reading in the separate input strings. Output values like power etc work correctly, I assume this is what most people look at daily (at least I do ) so the basic function still works.....

As for the station IID the plugin setup page also describes how to obtain this.

As said, I 'll fix it on return

[HansOtten]

Indeed the description is on the configuration part!

I was confused by the Power Station ID prompt versus the description 'station ID' as a string of characters, where I saw a string of digits only.

The timings of the refresh interval are not working the way it needs to be.

When setting the refresh interval to 10 seconds the script pulls every second...
When setting the refresh interval to 30 seconds the script pulls the first time after 30 seconds after that it puls every second...
When setting the refresh interval to 1 minute the script pulls every 10 seconds.
When setting the refresh interval to 5 minutes the script pulls the first time after 5 minutes after that it pulls every 10 seconds...

Greetings

I can confirm, did not notice it yet, was happy that it worked again at last.

Hi,

Im trying to make some scripts but im getting stuck at the output from the GoodWe.

Why is there a W (watt) behind the first number (svalues)?

Knipsel.JPG (39.47 KiB) Viewed 2514 times

When using this line of code i get an error because I need only numbers. But not there is a number and a letter.

Code: Select all

EnergyImportLow, EnergyImportHigh, EnergyExportLow, EnergyExportHigh, PowerImport, PowerExport = otherdevices_svalues[P1MeterDeviceName]:match("([^;]+);([^;]+);([^;]+);([^;]+);([^;]+);([^;]+)")

Lua doesn't like that. I also think its not needed because the actual sensor adds this on its own.

Knipsel1.JPG (20.25 KiB) Viewed 2514 times

Is it possible to remove the W after the number?

Good questions that @JanJaap can answer but he is on holiday now. So be patient.

Is er ook ergens een handleiding (stappenplan) te vinden om mijn Goodwe succesvol in Domoticz zichtbaar te krijgen?

See https://github.com/janjaapko/domoticz-GoodWeSEMS

[JanJaap]

Right so I'm back

I've added a couple of improvements to the plugin, as version 2.0.4 (a restart of Domoticz is required to see the new config description in Domoticz):
- handling the expected exceptions much neater so they do only add 1 logline
- added a fix for the 'unpack' error reported by multiple people which caused the plugin to fail before it would read in data of the second (and 3rd and 4th if available) input strings
- I improved the configuration page of the plugin a bit, so it should be a bit more clear what to do. Still, this requires users not be afraid of computer stuff

Hope all is fine now again. I will look into dealing with more than 1 inverter later. I will describe how to fetch the API response using postman in the Wiki pages of the plugin.

[Brutus]

Hi there,

Hope you had a nice vacation.

What about the things I noticed? The unwanted W in de svalues en de script running not at the given time option?

Greetings

[JanJaap]

Right, so the W(att) is not something the plugin does but that comes from how Domoticz deals with these devices, so can't help you there (and I try to avoid lua because python is much nicer). This topic is about the plugin, not about anything you can do with the data in domoticz.

I'll have a look at the updates later, although they look OK on my RPi.
