Home Assistant Device Triggers

Device triggers allow automations to be triggered by device-specific events, like button presses or motion detection.

Note: Device triggers/conditions/actions are optional UX features, not Integration Quality Scale (IQS) rules — unlike diagnostics and repairs, they are not among the 52 IQS rules. Don't implement them to advance an IQS tier; only add them when the device genuinely benefits from device-based automation.

When to Use Device Triggers

Use device triggers when:

• Device has physical buttons or inputs
• Device generates events (motion, doorbell press)
• Hardware state changes need automation triggers
• Standard entity triggers aren't sufficient
