It has 52 installs sharing analytics, works locally and was last updated August 29, 2026. WhenHub is a Home Assistant integration that tracks trips, one-time dates, yearly events and holidays with countdowns. It supports four event types: multi-day trips, one-time milestones, yearly anniversaries, and special events such as Christmas, Easter, daylight saving changes or custom patterns. Each event gets sensors for days until or since a date, binary sensors such as trip active today, and an image entity, and events also appear in a combined calendar. A date can come from a fixed value or from another date or timestamp entity, and an event can carry an image, a link and a Markdown memo. Events can notify through Repairs when they expire, and actions let automations create, update or delete events. It works locally and is set up in the UI.
