Export Rates not respecting basic rate (Kraken / EDF)

[icornish72]

Describe the bug
I have set up the Kraken component with EDF. This fails to get the export rates.
I have also set up the basic rate export (its a fixed 15p), but this is ignored.

Expected behaviour
If the component getting the export rates fails, it should use the Basic rate export defined.

Predbat version
8.37.6

Environment details

• Inverter and battery setup
• FoxEss 6Kw, Modbus, 18Kw battery stack
• Standard HAOS installer or Docker
• HAOS Install
• Anything else?

Screenshots
If applicable, add screenshots to help explain your problem. The most useful ones can be your battery chart, the Predbat HTML plan and your current settings in HA.

Note that the Kraken module seems to overwrite the metric_octopus_export value with a pointer to the Kraken sensor, which then fails

Predbat debug yaml file
This is important for any plan related issues.

Once you have captured the issue go to the Web UI, in the Dash tab click on predbat_debug.yaml and wait 30 seconds for it to download. Select 'keep' if your Web Browser thinks the file is dangerous.

Rename the download file to predbat_debug.yaml.txt and upload it to GitHub. This will allow your plan to be reproduced and also stores all your settings for review.

please include the full apps.yaml or debug file, not an excerpt. It could be mis-formatted

thanks

Is this sort of by design, you should use the 'rates_export_override' if you want to override the automatic rates.
