To add the History Graph card to your user interface, click the menu (three dots at the top right of the screen) and then Edit Dashboard. Click the Add Card button in the bottom right corner and select from the card picker.
All options for this card can be configured via the user interface.
YAML Configuration
The following YAML options are available when you use YAML mode or just prefer to use YAML in the Code Editor in the UI.
Configuration Variables
Hours to show in graph. Minimum is 1 hour. Big values can result in delayed rendering, especially if the selected entities have a lot of state changes.
Options For Entities
If you define entities as objects instead of strings, you can add more customization and configuration:
Examples
type: history-graph
title: 'My Graph'
entities:
- sensor.outside_temperature
- entity: media_player.lounge_room
name: Main player
Or with longer time frame, and multiple entities (as long as they share the same unit_of_measurement) in one graph:
type: history-graph
title: "Temperatures in the last 48 hours"
hours_to_show: 48
entities:
- sensor.outside_temperature
- entity: sensor.lounge_temperature
name: "Lounge"
- entity: sensor.attic_temperature
name: "Attic"
