AI-Powered Doorbell: Use Cases and Implementation in Home Assistant

AI-powered doorbells are transforming how we interact with visitors and manage our homes. With Home Assistant, you can leverage AI to build intelligent doorbell systems that go beyond simple motion detection. This guide explores practical use cases and implementation strategies using Frigate GenAI and Home Assistant AI Tasks.

Frigate GenAI vs Home Assistant AI Tasks

When integrating AI into your doorbell system, you generally have two paths within the Home Assistant ecosystem:

• Frigate GenAI: Best if you already use Frigate for local object detection. Frigate GenAI can send snapshots to a large language model (LLM) for deeper analysis, such as recognizing a delivery or describing activity at the door.
• Home Assistant AI Tasks: A native integration that lets you define specific AI tasks (for example, “Is this a person or a package?”) and run them with a supported local or cloud AI provider.

Your choice depends on whether you prefer to extend an existing Frigate setup or stay within native Home Assistant flows.

Use Case 1: Intelligent Visitor Interaction

Traditional doorbells only alert on motion. An AI-powered doorbell can identify who or what is at the door and trigger context-aware automations.

Implementation with Frigate GenAI

1. Configure Frigate to capture snapshots on detection events (for example, person, car).
2. Configure Frigate GenAI to send snapshots to your LLM with a concise prompt like: “Describe person or object at the door. Is this a delivery driver, a known visitor, or a stranger?”
3. Create a Home Assistant automation triggered by the Frigate GenAI result.
   • If the result is “Delivery driver with a package,” announce: “Please leave the package by the door.”
   • If the result is “Known visitor (for example, a family member),” announce: “Welcome home!”

Use Case 2: Package Management and Theft Deterrence

Package theft is a common concern. AI can monitor packages and deter theft with timely, contextual automations.

Implementation with Home Assistant AI Tasks

1. Define an AI Task that analyzes a doorbell snapshot for the presence of a package.
   • Task: “Is there a package visible in the image?”
   • Trigger: Doorbell press or motion detection followed by a short period of inactivity.
2. When a package is detected, log the event and send a notification with a snapshot and description.
3. If a package is present and a person is lingering near it, trigger a deterrent action.
   • Automation: Flash the porch light and play a chime or warning sound.

Use Case 3: Enhanced Security and Anomaly Detection

AI can help detect unusual behavior that might indicate a security issue, such as tampering or loitering.

Implementation Details

• Anomaly detection: Combine Frigate object tracking with AI Tasks to identify patterns like someone standing still for an extended period or moving erratically.
• Alerting: Use Home Assistant notifications to send rich alerts with AI-generated descriptions and snapshots.
• Automation example (YAML):

alias: Doorbell - AI Anomaly Alert
id: doorbell_ai_anomaly_alert
mode: single

trigger:
  - platform: state
    entity_id: sensor.frigate_doorbell_anomaly
    to: 'true'

action:
  - service: notify.mobile_app_phil_iphone
    data:
      message: >
        Doorbell activity: {{ trigger.to_state.attributes.description | default('Anomaly detected') }}
      data:
        image: "/local/doorbell_snapshot.jpg"

Tips and Best Practices

• Keep prompts short and outcome oriented; avoid overly broad questions to control cost and latency.
• Prefer local processing for privacy when possible; fall back to cloud for advanced models if needed.
• Store snapshots locally (or via an add-on) so downstream automations can reference predictable paths.
• Test with representative daylight and nighttime images; tune thresholds and motion zones to reduce false positives.
