index out of range & unable to decode request - But lot's of values are received successfully #106

Closed FrederikP closed 1 year ago

FrederikP commented 1 year ago

Hi I'm getting errors on every scan, and I'm wondering why.

My setup: SH10RT-V112, latest docker image (0.5.0), WiNet-S dongle - Wifi

connection: modbus -> port 502

Lot's of registers are actually successfully read and sent to mqtt. But I'm wondering why these errors come upon every scan.

Here is the output of one scrape with debug logging enabled: https://gist.github.com/FrederikP/349dcbbd5566f0f959f6de19eb5727eb

Is this a bug or did I misconfigure something? I will gladly provide more info if needed. Thank you very much

The modbus implementation on the WiNet-S dongle is buggy at best. Try the HTTP option.

Wow, quick answer. Thanks!

With

 connection: http

it says that model detection fails. When I additionally set

  model: "SH10RT-V112"

Then I'm getting the errors below:

I also tried other ports (e.g. 80) without success. It still attempted 8082. Anything I'm missing?

"Anything I'm missing?" yes, better documentation from me :P Can you load the web ui via http://192.168.2.21 ? it seems like the dongle may have crashed, and need to be restarted / unplugged & re plugged in again

FrederikP commented 1 year ago

You are absolutely correct. Something crashed and after unplugging and replugging in again, it works with connection: http. Thank you very much. One more thing I noticed is that, even though my WiNet-S dongle is connected to my wifi, it's also in hotspot mode and I can't seem to find a way to deactivate it. Do you know how by any chance? Not really a problem with your tool though ;)

Thanks for this great open source project.

The AP mode still on it a bug in the later firmware. It used to be off. Hopefully they fix it in a new release.
