how to access the container image?

[imp1sh]

Hi,

do you offer a ready to use container image? What is the url to pull it?

Thanks

Well I've wasted quite some time now to get this running. I've build the image myself and deployed it to my container host. It just won't work. Weirdly it always tries to resolve the inverter IP value, even it's an IP address already. When using a hostname it will always result in NXDOMAIN, even the record is valid. Getting a python crash in the container like this:

File "exporter.py", line 235, in main
    inverter_metrics.run_metrics_loop()
  File "exporter.py", line 158, in run_metrics_loop
    self.collector_register()

    return loop.run_until_complete(main)

    return future.result()
  File "exporter.py", line 138, in create_collector_registers
    inverter = await goodwe.connect(INVERTER_IP)

Hi, first, sorry for the delay. I haven't seen your question.

this is probably something on your side. I don't have a ready build image, but you can easily build it yourself with: docker build -t <image name>:<version> . I've already updated the documentation with this information

about the error... you need to use the IP Address, not hostname. be also sure, that the host with docker is on the same network as the inverter. if you scrape from someone else, or via an external IP address, be sure to have opened the UDP port 8899 on your router.

you can try to debug it via your PC/laptop. Just be on the same network as inverter, install python, and run: python src/exporter.py --port 8787 --inverter 192.168.2.15 (put there your IP, port can be random)

You should see something like: GOODWE DATA EXPORTER v1.4.4

polling interval: 60s inverter scrape IP: 192.168.2.15 total PV power: 5670W spot price scrape: Enabled spot price scrape interval: 0:30:00 min exporter started on port: 8787
