I copied your code into developer tools/templates and started adding debugging to it to work out what its doing. Didn't get to the end as my battery is empty, but here's where I got to: |

Thanks for your help. Someone else has offered help on the HA forums and their template collects the data but still doesn't quite work; in the data for today an empty_event should occur at 22:30 ({'time': '22:30', 'value': 0.76},), but it's showing as no battery predictions available. `- variables: |

might have it here, can't be certain; it still returns no battery predictions available, but with my current data, that's true. i'll update when ive checked it: {% set today_midnight = today_at() + timedelta(days=1) %}
{% set pred_data = state_attr('predbat.soc_kw_best', 'results') %}
{% set pred_list = [] %}
{% if pred_data %}
{% for ts_str, value in pred_data.items() %}
{% set dt = strptime(ts_str, '%Y-%m-%dT%H:%M:%S%z') %}
{% if dt < today_midnight %}
{% set pred_list = pred_list + [{
'time': dt.time().strftime('%H:%M'),
'value': value | float(0)
}] %}
{% endif %}
{% endfor %}
{% endif %}
{% set predictions = pred_list | sort(attribute='time') %}
{# Now use the variable predictions (a list) in your filters #}
{% set charge_events = predictions | selectattr('value', '>=', full_charge) | list %}
{% set empty_events = predictions | selectattr('value', '<=', empty_level) | list %}
{# Finally, output your message based on the lists #}
{% if predictions %}
Today's battery forecast:
{% if charge_events %}
→ Full charge at {{ charge_events[0].time }}
{% endif %}
{% if empty_events %}
→ Empty at {{ empty_events[0].time }}
{% endif %}
{% if not charge_events and not empty_events %}
→ Range: {{ predictions|map(attribute='value')|min|round(1) }}kWh to
{{ predictions|map(attribute='value')|max|round(1) }}kWh
{% endif %}
{% else %}
No battery predictions available
{% endif %} |

this doesn't work for me I set {% set full_charge=13.0 %} then tried the code above and got 'no predictions available' despite the battery falling below 0.8 and above 13: No battery predictions available {'2025-02-03T21:25:00+0000': 0.648, '2025-02-03T21:30:00+0000': 0.55, '2025-02-04T03:30:00+0000': 0.55, '2025-02-04T03:35:00+0000': 0.877, '2025-02-04T03:40:00+0000': 1.205, '2025-02-04T03:45:00+0000': 1.532, |

action: tts.speakIt's announcing the cheap rate slots, the currently connected car and the current SoC of that car correctly, but as far as comparing the time slots goes etc, it's a nightmare. I think not least because the timestamps are formatted slightly differently, octopus being for example '2025-02-21T13:56:00+00:00' and predbat being for example 2025-02-21T14:20:00+0000. a lot of that could be removed/simplified with only 1 EV, but doesnt change the issue with comparing time slots/analysis. |

Hello, I'm trying to make a HA automation that takes predbat.soc_kw_best attributes, checks whether the SoC will hit max and or min (in my case 19.05 and 0.76), get the times (if any) up to midnight and announce them via tts, but I'm struggling with the code. My attributes as an example:

The tts announcement based on the above would be something like "batteries empty at 22:30"
The closest I've got is this, but it either won't announce anything, or will say no battery predictions available:
