When I use the API to fetch data from the SEMS portal, it logs me out from my iPhone app and I need to log back in. This happens whenever the data is fetched (so roughly every 30 seconds) so it is very annoying. Is there a way around this? Thanks!

It should probably just raise a simpler error than "ugh, die".

I had been using it for a while to fetch data from my solar panels, and after a couple months my IP got banned. The app didn't work on my home network and the inverter was not able to send out data. I had fixed it by tunneling all GoodWe data through a VPN via my router, and after about a year my IP-ban got removed. But I digress.

Have you had any experience with, or is there any documentation on GoodWe's rate limit? I was polling their API 12 times per hour, with 5 minute intervals. I want to use this project again to act as a bridge between my GoodWe solar inverter and a MQTT broker, and I will probably fetch the data once every 30 minutes, and only between certain times when the sun is out as a safety measure.

The arguments passed to SingleInverter.get_current_readings:

are not forwarded to API.get_current_readings. When the number of maxretries is set to 1, it's still 5 due to the default value of 5 in API.get_current_readings. Also the recursive call should not happen in SingleInverter.get_current_readings as it already happens in API.get_current_readings.

Furthermore, the function should return data, but it returns retval set to None.

This is what the function should imho look like:

 def get_current_readings(
        self,
        raw: bool=True,
        retry: int=1,
        maxretries: int=5,
        delay: int=30,
        ) -> Any:
        """ grabs the data and makes sure self.data only has a single inverter """
        # update the data
        super().get_current_readings(raw, retry, maxretries, delay)
        # reduce self.data['inverter'] to a single dict from a list
        
        if self.data.get("inverter"):
            self.data["inverter"] = self.data["inverter"][0]
        return self.data

Something something permissions?

I have 4 sites. All of them showing offline at the same time while https://www.sems.com.cn/ showing working. Any answer or solution for this situation? 😭😭😭

I now have 2 Goodwe inverters, and would like to be able to pull data for both. How can I achieve this? I would like to dump all data to JSON (I currently useprint(json.dumps(gw.data), file=f)

When I try to readout some values using your library, I keep getting the following response:

ERROR:root:RequestException: 403 Client Error: Forbidden for url: https://semsportal.com/api/v1/PowerStation/GetMonitorDetailByPowerstationId
ERROR:root:RequestException: 403 Client Error: Forbidden for url: https://semsportal.com/api/v1/PowerStation/GetMonitorDetailByPowerstationId
ERROR:root:Failed to call GoodWe API url='https://semsportal.com/api/v1/PowerStation/GetMonitorDetailByPowerstationId'

I have been using it successfully for quite a while now, but recently it stopped working. Do you have any idea how to solve this? Or am I doing something wrong?

I will first explain my setup, and then the problems I am facing.

1. GoodWe GW5048-EM Hybrid Inverter with an eSTORE 10.3kWh LiFePO4 battery attached with 6.1kW of PV (Inverter 1)
2. GoodWe GW5048-EM Hybrid Inverter with with 6.6kW of PV and NO BATTERY attached. (Inverter 2)

To be clear, I think most of these may be issues with the portal, NOT your code, but I will mention it all here just in case.

When I was using just the first inverter, things were fine. Data being read was accurate. Adding the 2nd inverter to the mix made things a complete mess. Here are some of the issues:

1. SOC instantly halved (Inverter 1 SOC at 80%, Inverter 2 SOC at 0%) SEMS displays 40% SOC... even if its aware there is no battery on the 2nd inverter.
2. Power that I BUY from the grid is also doubled (I think the 'smart meters' are both measuring the same power coming into the property, and SEMS adds them together.. So if I am drawing 700W from the grid, its counted by both smart meters are shows 1400W)
3. With just Inverter 1 connected "SelfUseOfPV" used to include the power put into the battery.. this no longer seems to be the case, as sometimes I will have charged the battery from 10% to 100%, yet "SelfUseOfPV" is only 3kWh for the day (this is completely wrong.. it would be more like 15-20kWh)
4. Sometimes the portal shows the LOAD as something like 17W (as in the house is drawing 17w.. this is obviously incorrect)
5. Sometimes the portal shows I am EXPORTING/SELLING more than my PV is generating, even whilst still charging the battery, and feeding the LOAD of the house.. eg, PV is generating 10kW, battery is charging at 2.6kW, load is 1kW, exporting/selling 12kW..

Im sure there are more issues, but it seems that the SEMS Portal is NOT a reliable source at all currently. I will be discussing this with GoodWe tomorrow, but do not have high hopes of them quickly fixing these issues.

Do you know if there is a way to get data directly from the inverter itself? I used to use RS485->USB on my old ABB/PowerOne inverter.

Hi, got this error since yesterday:

WARNING:root:HTTPSConnectionPool(host='globalapi.sems.com.cn', port=443): Max retries exceeded with url: /api/v1/PowerStation/GetMonitorDetailByPowerstationId (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:1108)')))

Could change the global_url to : 'https://semsportal.com:443/api/'
or add an option to switch between the 2 or try the 1 url then the other?

since march i can't get this api working.

Is this API still working?

I'm trying to run the example.py.. I've set up my details in config.py and I can see that is coming through.

Apologies if this is something obvious (I'm new to python), but it fails with this output:

I noticed at night when there is no generation, I don't even get data for other things like inverter temperature or voltage etc.
I have yet to investigate further. Unsure if this is the API returning no data when there is no generation or whether it is pygoodwe not handling it properly.

Hello,
Can you add a ReadMe with more information about this PyGoodWe?
How can you use it. How to get the information of the power station?
Functions like GetCurrentGeneration() or something like that.

I want a documentation of API. Have anyone?

Hey, I noticed that the function GetDataPvOutput() results in float object is not subscriptable error because of the following lines:

data["v4"] = self.getLoadFlow()[0] # power consumption
data["v5"] = self.get_inverter_temperature()[0] # inverter temperature
data["v6"] = self.getVoltage()[0] # voltage

After removing the list indices of [0] it works fine given that getLoadFlow returns a single float rather than a list.

New code:

data["v4"] = self.getLoadFlow() # power consumption
data["v5"] = self.get_inverter_temperature() # inverter temperature
data["v6"] = self.getVoltage() # voltage

I want import my Goodwe SEMS Data in IoBroker, so I used the work from https://forum.iobroker.net/topic/34626/goodwe-wechselrichter-und-iobroker. When im tested it following problem comes up. Im no specialist in python Syntax.

pi@Raspberry-Pi4:~ $ python /home/pi/pygoodwe-master/test.py

I imported the master and moving the config.py.example to config.py and enter data.

Can anyone help me to use the Script?

Hi, thank you for your libary. I tried to install it, but when I run test_pygoodwe.py I only get the message:

test_pygoodwe.py::test_instantiate SKIPPED (Could not find data file 'testdata.json') [ 12%]
Skipped: Could not find data file 'testdata.json'

and so on for all the data. Can you may help me.
Have a nice Day!

Hello,

I have a Goodwe hybrid inverter and want to use your pygoodwe. But I dont know how to use it?!

Can you please write a little HowTo?

Dependabot couldn't authenticate with https://pypi.org/simple/.

You can provide authentication details in your Dependabot dashboard by clicking into the account menu (in the top right) and selecting 'Config variables'.

View the update logs.

keeps repeating following message(retries are not incremented):

• Failed to call GoodWe API url='https://semsportal.com/api/v1/PowerStation/GetMonitorDetailByPowerstationId'
• no inverter data, try 1, trying again in 30 seconds

I get an issue with the module hanging when trying to download the "spreadsheet" data. Is there another function that can download the full set of daily readings?

Below is the code snippet that hangs
gw.getDayDetailedReadingsExcel()

Hi there
wondering if anyone else experienced issues with grabbing data.
everything worked fine for me for arround 9 monts, but since start of december its not working anymore and i keep getting these errors:

ERROR:root:RequestException: 403 Client Error: Forbidden for url: https://semsportal.com/api/v1/PowerStation/GetMonitorDetailByPowerstationId
ERROR:root:Failed to call GoodWe API url='https://semsportal.com/api/v1/PowerStation/GetMonitorDetailByPowerstationId'

seems to me like there has been some changes somewhere from SEMS side
anyone else experiencing this?

BR, Cravvler
