How do I install Atomic Calendar Revive in Home Assistant?

Install via HACS (Home Assistant Community Store) by adding the repository, or manually download the release from GitHub and add it to your Lovelace resources. The QuickStart guide in the documentation provides detailed steps.

Atomic Calendar Revive vs standard Home Assistant calendar card?

Atomic Calendar Revive offers far more customization, including advanced filtering, progress bars, and multiple view modes, while the default card is basic with minimal options. It's designed for users needing flexibility over simplicity.

How to filter events by keyword in Atomic Calendar Revive?

Use the keyword allow and block lists in the card configuration via the Lovelace UI editor or YAML. This lets you include or exclude events based on specific terms to display only relevant information.

Does Atomic Calendar Revive work with iCloud calendars?

Not directly—it only supports Google Calendar and CalDav. For iCloud, you might need to use CalDav if iCloud offers it, or explore third-party integrations to bridge the gap.

How to switch between list and calendar views?

Configure the 'view' option in the card settings to either 'list' for a chronological event list or 'calendar' for a traditional monthly layout, with the change reflected immediately in Lovelace.

Why is my Atomic Calendar Revive card not showing events?

Check that your calendar entity is properly configured in Home Assistant, verify the card's filtering settings aren't hiding all events, and ensure compatibility with your HA version as per the documentation.
