borft / py-goodwe Goto Github PK

Bedankt voor dit handige stukje code!
Ik krijg helaas bij het uitvoeren van de code een foutmelding(begin gaat wel goed en data wordt uit de GoodWe gehaald):
Traceback (most recent call last): File "run.py", line 88, in <module> cur.execute(query, values) psycopg2.errors.SyntaxError: syntax error at or near "ON" LINE 1: ....5,6553.5,148,49.97,655.35,655.35,4.3,1.1,1281.5) ON CONFLIC...
Ik maak gebruik van een oude Synology NAS, waardoor ik alleen psycopg2-binary kan installeren. Dus wellicht dat mijn foutmelding daar mee te maken heeft. Heb je een idee hoe ik dit zou kunnen oplossen?

Hello, I have a problem and wanted to check if there is any idea to proceed.
I have GoodWe inverter HF_E20, with LAN module (not wifi). PV master app from mobile phone works (wifi bridged to the same network), inverter also sends data to semsportal.

When I try the first phase manually using netcat, I succeed:
$ nc -u 192.168.42.150 48899
WIFIKIT-214028-READ

192.168.42.150,34:ea:e7:98:25:96,HF_E20

However, when trying with py-goodwe, I am not getting any response.

$ python3 run.py
Retrying 2 timed out
Retrying 1 timed out
Retrying 0 timed out
failed: Could not get proper data after retrying

I have in config.ini
[goodwe]
ip =192.168.42.150
port = 8899

I think the inverter doesn't react to the message \x7f\x03\x75\x94\x00\x49\xd5\xc2. I've tried to put there a test msg \xAA\x55\xC0\x7F\x01\x02\x00\x02\x41 instead, which has produced some response apparently, as the message changed to
Retrying 1 Invalid data (unexpected length: 85

I've tried to send these two manually as well:
$ echo -e "\x7f\x03\x75\x94\x00\x49\xd5\xc2" | nc -u 192.168.42.150 8899
(no response)

$ echo -e -n "\xAA\x55\xC0\x7F\x01\x02\x00\x02\x41" | nc -u 192.168.42.150 8899
�U��L0707CGW10K-ET 9010KETU21BW442302041-19-S0C�

So the communication works and probably just the default command to get data is not working for this type.

More info - I have scanned the inverted with nmap, I can see I have opened TCP 80 and 502 and UPD 8899 and 48899. When tried to discover more about modbus on TCP502, I didn't get anything more detailed.

Any hint what/how to change, please?
Thank you,

Hey!
Thanks for this great tool, I will try it out as soon as my PV goes online. But do you mind adding support for InfluxDB?
When you don't want to add it, i will read into your code and try to implement it on my own, but I got little free time atm.
So it could take a while :)

Because for ppl which use InfluxDB and Grafana we can keep our setup as minimal as possible.

I will happily contribute a Grafana Dashboard, as soon as i can try it out. :)
