Logfile Warnings help with apps.yaml

[d2too]

Hi,
I'm currently seeing the below warnings in my logfile and wondered if anyone can help. I have attached my apps.yaml if that helps.
'''

apps.yaml.txt

Please supply further information.

Version of Predbat? (and the other details asks for in an issue)
Installation. Is it HAOS, Docker, ?

Please download and attach from WebUI/dash
apps.yaml
predbat_debug.yaml
predbat.log
predbat_plan.htlml

The file for apps.yaml that you have included looks very different from the template file supplied for apps.yaml.
The most important file is predbat.log as the issues that you have listed all refer to predbat.log.

Please check against documentation, especially for battery charge and discharge curves:
https://springfall2008.github.io/batpred/apps-yaml/#battery-chargedischarge-curves

solcast pv
https://springfall2008.github.io/batpred/install/#solcast-home-assistant-integration-method

The apps.yaml file you have attached looks incomplete and contains some entities that I do not have on my givenergy installation.
e.g.

  # -----------------------------
  # AUTOMATIC BATTERY CURVES & POWER INVERSION
  # -----------------------------
  battery_auto_curve: true
  battery_curve_hours: 24
  battery_curve_update_interval: 6

  battery_auto_invert: true  # <---- automatically flips battery power polarity

Where have these lines come from?

Hi Rob, thanks for the reply.
I have attached the log files as per your comment.
As I couldnt get it to work without the errors I thought I was ask AI and it put in those lines as a suggestion.
Im running predbat within HA and Not as a docker also its version 8.35.1

predbat.log

Where have you got the automatic battery curve lines from?
In your predbat.log, there are 1507 warnings, all referring to battery curves.
e.g.

2026-03-30 13:20:54.613226: Warn: Cannot find battery discharge curve (missing history), one of the required settings for soc_kwh, discharge_rate, battery_power and predbat.status do not have history, check apps.yaml

In the apps.yaml template, you should see something like this (these are mine):

  battery_charge_power_curve:
  # generated 10-07-2025
    100 : 0.12
    99 : 0.12
    98 : 0.12
    97 : 0.12
    96 : 0.12
    95 : 0.34
    94 : 0.58
    93 : 0.68
    92 : 0.74
    91 : 0.86
    90 : 0.91

  battery_discharge_power_curve:
# generated 10-07-2025
    20 : 1.0

The easiest way is to set these up using 'auto', as outlined in the documentation.
You could comment out your lines and try these.

Something like this:

  battery_charge_power_curve: auto
  battery_discharge_power_curve: auto

Do read the extensive documentation on battery curves:
