Federico Zivolo added a calendar platform to Home Assistant’s existing Apple iCloud integration. Each iCloud calendar becomes a read-only calendar entity that shows the event in progress or the next one due, using the account and session already configured in Home Assistant.
The platform keeps a local window from the previous day through the coming month for quick current-event lookups, while broader calendar queries still go directly to iCloud. Creating and editing events is deliberately outside this work; companion documentation makes that read-only scope explicit.
