Add walls and areas

Walls and areas make the composition useful. Walls help the space look like a real place. Areas give names to the parts of the home where events, cameras, and automations happen.

You do not need to draw a perfect architectural plan. Start with the structure that helps Toposync understand where things are.

Available structural layers​

The structural extension currently provides:

  • Wall: a simple line segment in 2D.
  • Opening: a cutout on a wall.
  • Door: a door cutout on a wall.
  • Window: a window cutout on a wall.
  • Rectangular area: a quick rectangle for simple regions.
  • Freeform area: a polygon for irregular regions.
  • Rectangular room: a rectangle that also creates surrounding walls.
  • Freeform room: a freeform region that also creates walls.

Use the simplest tool that fits the space.

Areas are important​

Areas are not only visual. They become useful later for:

  • filtering detections by location;
  • naming events;
  • deciding which notification is relevant;
  • connecting a camera view to real-world regions;
  • triggering Home Assistant actions by context.

For example, a person on the sidewalk may be normal. A person in the backyard at night may be important. The area gives the event context.

Suggested first pass​

Start with:

  1. The outside outline of the home or area you care about.
  2. The main rooms or outdoor zones.
  3. A few important areas such as entrance, driveway, garage, pool, backyard, or gate.
  4. Doors and windows only when they help orientation.

Do not spend the first session drawing every detail.

Naming tips​

Choose names that will make sense in events and notifications:

  • Front gate
  • Driveway
  • Garage
  • Pool
  • Backyard
  • Living room
  • Kitchen

Short, stable names are easier to use in pipelines.
