Configuration

sensor_name

The entity_id of your EnergiDataService Sensor. Examples:

{% set sensor_name = "sensor.elpris" %}

{% set sensor_name = "sensor.energi_data_service" %}

consumption

The amount of kW used. Examples:

Hybrid Electric car charging at 230 volt * 16 amp

{% set consumption = 230 * 16 / 1000 %}

Washing machine using 1500 watts

{% set consumption = 1500 / 1000 %}

duration

How long will it run for. Examples:

Hybrid Electric car charging 10 kWh battery: (Assuming sensor.car_battery_level is the battery level %)

{% set duration = timedelta(hours = (10 / consumption) * (1 - (states("sensor.car_battery_level") | float / 100))) %}

Electric car charging 75 kWh battery up to 80%: (Assuming sensor.car_battery_level is the battery level %)

{% set duration = timedelta(hours = 0.8 * (75 / consumption) * (1 - (states("sensor.car_battery_level") | float / 100))) %}

Washing machine running 2.5 hours

{% set duration = timedelta(hours = 2, minutes = 30) %}

start_time

First possible time to start. Typically:

{% set start_time = now() %} 

To show all values use:

{% set start_time = today_at("00:00") %} 

end_time

Deadline for when the operation should be finished. (For example departure time).

Maximum

{% set end_time = today_at("00:00") + timedelta(days=2) %} 

Tomorrow at 7:30

{% set end_time = today_at("7:30") + timedelta(days=1) %} 

In 12 hours:

{% set end_time = now() + timedelta(hours=12) %}
