*sensor.grid_metrics_total_cost holds price for current hour
*binary_sensor.energy_prices_electricity_is_cheapest is On during few cheapest hours
*binary_sensor.energy_prices_electricity_is_below_average is On during below average price hours

Everything is calculated including the distribution part of the price.

And create following template sensor sensor.inverter_battery_precharge:

{% set n = now() %}
