Home Assistant Device Triggers

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

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
