Mm okay.
i just thougt it was possible just to extract the values one by one from the
{{cheapest_price_list}}
like:
{% set cheapest_hour_1 = ..... %}
{% set cheapest_hour_2 = ..... %}
{% set cheapest_hour_3 = ..... %}
{% set cheapest_hour_4 = ..... %}
if the price is then one of those, it will trigger the charger to turn on,
make it very simple
or if the datetime, instead of the price.
