Lovelace examples

Prices card

To show a simple card with todays prices you could use the multiple-entity-row card with the following yaml configuration:

entity: sensor.barry_sensor
type: custom:multiple-entity-row
name: Todays prices (kr/kWh)
unit: ' '
icon: mdi:cash-multiple
show_state: false
entities:
  - attribute: min
    name: Min
  - attribute: max
    name: Max
  - attribute: current_total_price
    name: Current
secondary_info:
  entity: sensor.barry_sensor
  attribute: average
  name: 'Average:'

Remember to change the entity to the correct entity generated for your setup

Price graph

To show a graph with today and tomorrows prices you can utilize the apexcharts-card card with the following example yaml configuration:

type: custom:apexcharts-card
apex_config:
  chart:
    height: 350px
graph_span: 2d
header:
  title: Electricity cost (kr/kWh) - Barry
  standard_format: true
  show_states: true
span:
  start: day
now:
  show: true
  label: Current
  color: purple
yaxis:
  - min: 0
series:
  - entity: sensor.barry_sensor
    name: Total price
    type: area
    curve: stepline
    color: b58e31
    stroke_width: 2
    float_precision: 2
    extend_to_end: false
    show:
      extremas: true
      legend_value: false
    data_generator: >
      return
      entity.attributes.raw_today.concat(entity.attributes.raw_tomorrow).map((entry)
      => {
        return [new Date(entry.start), entry.value];
      });

Remember to change the entity to the correct entity generated for your setup
