Home Assistant automation planner

Plan a Home Assistant automation before you buy the devices

Start from an automation goal, then check the required entities, hubs, connection path, feature limits, reliability risks, and Home Assistant YAML starter. Use it before buying Matter, Thread, Zigbee, camera, lock, sensor, or lighting devices.

What it checks

Entities, hubs, limits, reliability, and YAML

Home Assistant can automate many devices, but only if the right entities are exposed and the setup path is reliable enough. This page focuses on the automation path, not generic product specs.

Required Home Assistant trigger and action entities
Matter Controller, Thread Border Router, Zigbee coordinator, or bridge requirements
Feature limits when a vendor app exposes more than Matter or Home Assistant
Local-control, cloud dependency, mesh, and unavailable-state risks
Manual override, debounce, cooldown, and fallback needs before YAML
Home Assistant YAML starter with editable entity placeholders

Turn lights on when someone enters a room and turn them off when the room becomes empty.

Devices you already own

Recommended setup path
  1. Choose a presence or motion sensor that exposes stable entities to Home Assistant.
  2. Connect lights through a local path when possible, such as Hue Bridge, Matter, Zigbee, or a native integration.
  3. Generate YAML only after the trigger and light entities are visible.
Missing devices and hubs
  • Aqara Presence Sensor FP2
  • Eve Motion
  • Aqara Motion Sensor P1
  • Philips Hue Bridge
  • Home Assistant
  • compatible presence or motion sensor
  • light or lighting bridge
Feature and reliability limits
  • Presence sensors can require vendor app calibration.
  • Basic motion sensors may turn lights off while people are still still.
  • Cloud-only lights can add delay to automations.
Automation reliability checklist

These checks come before copying YAML. They reduce false triggers, stale states, manual-control conflicts, and unsafe security or power actions.

  • Use a sensor that exposes a stable occupancy or motion entity before writing YAML.
  • Add a cooldown or delay-off period so lights do not flicker when motion briefly clears.
  • Keep a manual override path for guests, movie mode, or sleep mode.
  • Handle unavailable sensors by leaving lights unchanged instead of forcing them off.

FAQ

What is the Home Assistant Automation Planner?

It is a scene-first planning tool for Home Assistant automations. It maps an automation goal to required devices, exposed entities, hubs, compatibility paths, reliability checks, and YAML starters.

Can it tell me which entities I need?

Yes. The planner highlights the trigger and action entities a Home Assistant automation needs, such as motion, presence, contact, lock, light, power, camera event, or notification entities.

Does it check Matter, Thread, Zigbee, and hub requirements?

Yes. It flags missing Matter Controllers, Thread Border Routers, Zigbee coordinators, vendor bridges, Home Assistant controllers, and local or cloud path risks.

Does it generate YAML?

Yes. It links each supported scene to a Home Assistant-compatible YAML starter that uses editable entity placeholders.
