Rooms and device numbering in installation projects

Define rooms, assign devices and check labels before generating installation documentation.

Prepared by EnergyHouse · Updated: 19 October 2026

Room names and device identifiers connect discussions with the client to the plan and materials list. When several installers work on the same project, consistent references reduce uncertainty about which installation point a particular item describes.

Workflow

Define room boundaries and names before placing devices. After moving an object between rooms, check its room assignment and description. Before exporting, review crowded parts of the drawing: labels should not obscure doors or other devices.

Drawing and naming rooms

Room outlines help assign devices to the correct rooms.

  1. In Rooms, select Draw a room and drag a rectangle around the room’s outline.
  2. For an L-shaped room, select Draw an irregular room. Mark the corners and close the outline by clicking the first point.
  3. Name the room. Select it later to edit its name or outline.

Editing, replacing and updating multiple devices

Click a symbol on the plan or an item in the list to open its details.

  1. Edit the name, room, route, cable, height or notes. Field changes are saved automatically.
  2. Replace product changes the model while keeping its location. Check which devices are selected for replacement.
  3. Bulk editing lets you select fields and target devices. Select only the intended items and apply the change.
  4. Use Undo to reverse a mistake.

Export a JSON project backup before changing many objects.

Layers and object visibility

Layers control what you see on the plan without removing devices from the project.

  1. Open Layers and select the object groups you need.
  2. Deselect groups that get in the way and check which floor is active.
  3. If an object disappears, check layers and filters before adding the device again.

Hiding a layer does not exclude its items from pricing. Change the estimate scope separately.

Try it in your own project

Open EH Designer on a computer with a mouse. Start with one room or part of the installation, review the result and expand your project. For available plans, see pricing.
