A custom component for Home Assistant to allow regular entities to be used as a calendar

Simply search for Entities Calendar in HACS.

Some new features may be made available in beta versions. To use these you need to enable betas for this integration in HACS. This can be done by toggling on the "Show beta versions" option when installing. If you have already installed it and want to enable betas, do the following:

• Open HACS
• Find the Entities Calendar integration under the Integrations tab
• Click the three dots menu button
• Select Reinstall from the menu
• Toggle on “Show beta versions”
• Select the latest beta version
• Click Install

calendar:
  - platform: entities_calendar
    calendars:
      - name: Bin Collection
        entities:
          - entity: sensor.bin_collection_general
            name: General Waste Collection
          - entity: sensor.bin_collection_recycling
            name: Recycling Collection
          - entity: sensor.bin_collection_garden
            name: Garden Waste Collection
      - name: Other Entities
        entities:
          - entity: sensor.other_entity1
          - entity: sensor.other_entity2
          - entity: sensor.other_entity3

By default the start and end time of the event will be determined based on the device_class attribute of the entity:

These will create all-day calendar events using the state of the sensor as the date.

These will create all-day events based on the last_changed attribute.

This can be overridden by using the start_time and/or end_time options.

Given three sensors:

• sensor.attribute_test - a sensor with a start_time and end_time attribute
• sensor.state_test - a sensor with a timestamp in the state but without a device_class of "timestamp"
• sensor.default_test - a sensor with a device_class of "timestamp"

The following configuration would be used:

calendar:
  - platform: entities_calendar
    calendars:
      - name: Entities
        entities:
          - entity: sensor.attribute_test
            name: Attribute Test
            start_time:
              timestamp_attribute: start_time
            end_time:
              timestamp_attribute: end_time
          - entity: sensor.state_test
            name: State Test
            start_time:
              timestamp_in_state: true
            end_time:
              timestamp_in_state: true
          - entity: sensor.default_test
            name: Default Test
