Error: Exception_raised array assignment index out of range

Exception raised since todays update.

When I try and view plan I get the message 'No plan available, Message plan data is loading...'

Predbat version v8.40.8

Environment details

• Fronius Gen24 plus 10Kw byd battery
• Standard HAOS installer
• Anything else?

I have been having trouble with the occasionaly extremely enormous load in the plan prior to this update, which i have attributed to the occasional unknown appearing in the data. These figures appearing in a single half hour load are generally many multiple of the full days load.

The sensor I using for load is 👍
- name: "Fronius Daily Consumption"
unit_of_measurement: "kWh"
device_class: energy
state_class: total_increasing
state: >
{% set from_grid = states('sensor.fronius_daily_from_grid') %}
{% set generation = states('sensor.fronius_daily_generation') %}
{% set to_grid = states('sensor.fronius_daily_to_grid') %}

      {% if from_grid not in ['unknown', 'unavailable', None] and 
            generation not in ['unknown', 'unavailable', None] and 
            to_grid not in ['unknown', 'unavailable', None] %}
        {% set from_grid_wh = from_grid | float(0) %}
        {% set generation_wh = generation | float(0) %}
        {% set to_grid_wh = to_grid | float(0) %}
        {# Raw calculation in Watt-hours #}
        {% set consumption_wh = from_grid_wh + generation_wh - to_grid_wh %}
        {# Convert to kWh for Predbat #}
        {% set consumption_kwh = (consumption_wh / 1000) | round(2) %}
        {{ [consumption_kwh, 0] | max }}
      {% else %}
        {# Use this.state or fallback to previous state to prevent dropping to 0 #}
        {% if this.state not in ['unknown', 'unavailable', None] %}
          {{ this.state }}
        {% else %}
          {{ states('sensor.fronius_daily_consumption') | default(0) }}
        {% endif %}
      {% endif %}

Im only evaluating Predbat currently as Im running the system based on a set of tarriff and time of day rules I have set . Im hoping the once I get predbat going smoothly it will provide a more optimal management plan for our inverter.

Thanks for your good work to date.
