Code snippet to get number of hours until the electricity is cheap(?).

	{% set hour_when = as_timestamp(state_attr('binary_sensor.nordpool_planner_time_when_low_electricity_price', 'starts_at'))\|int%}
	{% set real_hour = (state_attr('binary_sensor.nordpool_planner_time_when_low_electricity_price', 'starts_at')) %}
	Electricity is cheap at: {{ real_hour }}
	{% set time_now = as_timestamp(now())\|int%}
	{% set hour_now = time_now\|timestamp_custom('%H') %}
	{% set hours_until = -((time_now - hour_when)\|int/3600)\|int %}
	Hours left until cheap electricity: {{ hours_until }}
