Daily production stopped

[kanagawawave]

First thanks for this amazing repo, loving it. A few days ago, my daily production stopped. I'm doing anything wrong? I got no errors on my /var/log/solar/logger.log

How to proceed?

Are the graphs above working?

set the debug flag in the config.py file to True

You can see the result in /var/log/solar/solar.log. You might get an idea where the application is having trouble

Yes, the other graphs works fine and my debug is always true, no errors i think just normal logs like:

@edit Checking browser console i get "Could not find index for field name: Huawei_daily.Bal" any idea how to fix? influxdb seems ok

Seems you aren't able to poll the inverter. It opens a connection to 192.168.31.13, but not able to read any values.

If nothing changed (upgrades?), try running scanner.py. This might show if you can poll the inverter

Tried to run scanner and scanner_2 and nothing happens, maybe because night time? During day running solar.service we got:

I'm connected to inverter using wifi

Could be that your inverter goes to sleep at night? Not sure if the hibernating setting would help. Understand some inverters don't provide info at night.

Other than some values off, the log you got during the day seems ok. For instance you efficiency has a weird value. Could be that your WEG inverter ;) might have some registers work differently? You can compare the register map against the Huawei.py which is the default inverter model. However, it was working a week ago.

Moved from my server to rpi and seems to be working now. I'll keep updated if i find the cause. Thanks
