Triggers

Triggers are what start an automation. They fire when something happens in your home, like a light turning on, a door opening, or the sun setting. When a trigger fires, the automation checks its conditions and then runs its actions.

Browse the full list below, or use the search box to find a specific trigger by name or description. Each trigger has its own page with a step-by-step UI walkthrough, examples, and a complete field reference.
