Tap the Lamp, Skip the Device List

Key takeaways

• A dashboard that depicts your home lets people find devices by location.
• Creating the illustration and connecting it to working controls are separate jobs.
• Controls need enough space to tap and feedback that reflects the device’s actual state.
• Start with one room and compare everyday tasks against your existing dashboard.

Turning on a lamp should not require remembering whether it is “Living Room Light 2” or “Living Room Light 3.” As connected devices multiply, that small naming problem becomes a household interface problem. An illustrated dashboard in Home Assistant, a platform for managing smart home devices together, offers an appealing possibility: tap the lamp where you expect to find it.

Your household already knows the layout

The person who configured a smart home usually knows what every device name means. Everyone else has to learn the system administrator’s private vocabulary.

A picture of the room could remove some of that homework. Draw the floor lamp beside the sofa, connect that part of the image to its control, and someone looking for the lamp has a familiar place to start.

The appeal is spatial familiarity. The thought “I want the light beside the sofa” maps directly to a location on the screen.

Whether that makes the task faster is still something to test. A recognizable room can help people find their way, but a crowded illustration or an awkward viewing angle can make a simple task surprisingly fiddly.

Commission an interface, not just a picture

“Please draw my living room” is an incomplete brief for an interactive dashboard.

A real floor lamp is much smaller than a sofa. Preserve those proportions on a tablet, and the lamp might become difficult to tap. Interactive objects may need exaggerated dimensions or enough empty space around them for larger tap targets.

The illustration also needs a plan for showing state. A lit version and an unlit version of a lamp could communicate whether it is on. A short label or another visual indicator can help people who find the color difference hard to distinguish.

These decisions belong in the brief, before the artwork is finished.

So does the division of labor. Drawing the room does not connect it to your devices. Someone still has to define the interactive areas and wire each action to the right control. Agree on who supplies the artwork, who builds the dashboard, and what files each person needs.

A whole house can become a very small menu

A complete illustrated home might look excellent on a wall-mounted tablet. On a phone, its lamps could shrink into specks.

One option is to split navigation into two steps: select a room from the house view, then control its devices on a larger room view. That adds a tap, but gives each object more space.

Some controls also work better outside the illustration. Tapping a lamp is a plausible way to switch it on. Setting its brightness precisely may call for a slider. The picture can help people find a device, then familiar controls can handle the details.

The more consequential issue is actual device state. If the dashboard shows a glowing lamp the instant someone taps it, what happens when the lamp has lost its connection?

Sending a command and confirming that it worked are different events. The interface needs to make that distinction clear, so the picture remains a useful account of the home.

Give the living room an audition

Before commissioning an entire house, try three devices in one room: a ceiling light, a floor lamp, and curtains.

A rough sketch is enough to test the basic idea. Ask someone in your household to turn on the floor lamp without explaining the screen first. Watch where they tap. For the curtains, check whether they expect a tap to move them immediately or open another set of controls.

Then have them perform the same tasks on the existing list-based dashboard. Hesitation and accidental taps will tell you more than a preference for one visual style. Fixing those problems in a sketch is easier than revising finished artwork.

Plan for changes, too. Request separate background and device elements so adding a lamp does not require redrawing the room.

An illustrated dashboard earns its place when people can find the right device and understand its current state. The useful test is what happens when someone else walks up to it. Ideally, they turn on the lamp without asking what you named it.
