## Predbat is failing with Warn: Service call select/select_option data failed

Here's an example error message:

```text
2026-01-14 15:10:43.706153: Warn: Service call select/select_option data
{'option': '17:00:00', 'entity_id':
'select.predbat_fox_603j303046yp036_battery_schedule_charge_end_time'}
failed
```

This will happen if you have no actual selectors provided by integrations in Home Assistant before Predbat starts. You can workaround this by adding a
dummy selector to configuration.yaml and restarting HA e.g:

```yaml
template:
- select:
- name: "simple_select"
state: "{{ states('input_select.my_input') }}" # Current value
options: "{{ ['Option 1', 'Option 2', 'Option 3'] }}" # Available options
select_option:
- service: input_select.select_option
target:
entity_id: input_select.my_input
data:
option: "{{ option }}"

The template select example references an entity 'input_select.my_input' that needs to be created first. Consider adding a note that users need to either create this input_select entity or replace it with an existing entity in their Home Assistant configuration, otherwise this workaround will not work as intended.

## Why is my predicted charge % higher or lower than I might expect?

- Predbat is based on cost, so it will try to save you money. If you have the PV 10% option enabled it will also
