Home Assistant Dashboards: The Big Mistake to Avoid

Updated 5 November 2026 · Standard formula, shown below

The big mistake with Home Assistant dashboards is trying to show everything on one screen instead of designing around what you need to do. A useful dashboard makes frequent actions and important information easy to find; it does not need to display every device, sensor, and setting at once.

Why an all-in-one dashboard often fails

Home Assistant can bring together lights, climate controls, sensors, media players, switches, and other entities. That flexibility makes it tempting to add each item to a single view. The result can be a long, crowded page that is hard to scan, especially on a phone.

The problem is not simply appearance. When controls are buried among rarely used readings, a person may tap the wrong item or spend time searching for a basic action, such as turning off a light. A dashboard should help people operate and understand a home, not reproduce the full list of everything Home Assistant knows about.

A better starting question is: “What does someone need to see or do here?” That question leads to a dashboard organized around tasks and locations rather than a catalogue of entities.

Design around tasks and people

Think about the situations in which the dashboard will be used. A resident leaving home may want a quick view of doors, lights, and climate settings. Someone in a living room may care more about lighting and media controls. A wall-mounted tablet may need large, obvious buttons, while a desktop view can comfortably fit more detail.

Put frequent actions first: place commonly used lights, scenes, or climate controls where they are easy to reach.
Group by purpose: use views or sections for areas such as rooms, security status, energy information, or maintenance.
Show useful status: display information that changes a decision, such as whether a door is open, rather than every available measurement.
Consider other users: prefer clear labels and predictable controls over shorthand that only the dashboard’s creator understands.

Not every household needs the same layout. A guest-facing view, for example, may expose a few safe, straightforward controls without presenting administration tools or a detailed device inventory.

How Home Assistant dashboards work

Home Assistant’s dashboard interface presents information and controls through cards arranged in views. Cards can show entity states, offer controls, or present other kinds of information. The available options depend on the Home Assistant version, integrations, and dashboard configuration.

Dashboards can be customized in the interface, and advanced users can also work with configuration-based approaches. The key planning point is that an entity being available in Home Assistant does not mean it must appear on every dashboard. Automations, integrations, and dashboards have different jobs: an automation can act in response to conditions, while a dashboard helps a person inspect or control the system.

For example, a temperature sensor may be valuable to an automation but not worth displaying prominently if nobody needs to check it regularly. Conversely, a manual override for heating may deserve a visible control even when the system normally runs automatically.

Build a dashboard in manageable steps

List the main tasks. Write down the actions people perform most often and the status information they check. Keep the first list short.
Choose a simple structure. Create a few meaningful views or sections, such as “Overview,” “Rooms,” and “Energy,” rather than making one view carry every purpose.
Add only relevant entities. Select the controls and readings that serve those tasks. Use readable names and avoid duplicate cards that communicate the same thing.
Test on the real display. Check the layout on the phone, tablet, or computer people will actually use. A layout that looks tidy on a large monitor may require too much scrolling on a phone.
Refine based on use. Remove controls nobody uses, move important items higher, and make confusing labels clearer. Treat the dashboard as something to improve, not a one-time project.

It is often easier to begin with a small, dependable overview and add a card only when there is a reason for it. This also makes troubleshooting simpler: if a display becomes confusing or a card stops working, there are fewer places to investigate.

Common mistakes beyond clutter

Overloading the screen is the main design mistake, but several related choices can make a dashboard less dependable.

Using unclear labels: names such as “switch 3” may make sense during setup but are hard for another person to interpret later.
Making controls too small: compact layouts can be awkward on touchscreens. Leave enough space to distinguish nearby buttons and read status text.
Hiding important state: a control can look available without making it obvious whether a device is on, unavailable, or reporting an unexpected state.
Mixing actions with diagnostics: technical readings can be useful when diagnosing a problem, but they can distract from everyday controls. Put diagnostic detail in a separate view if it is not needed routinely.
Assuming every device is online: integrations and devices can become unavailable. A dashboard should make missing or stale information distinguishable where that matters.

Also avoid treating a dashboard as a security boundary. What someone can access depends on Home Assistant’s accounts, permissions, network setup, and other configuration—not merely on which cards are visible. For shared devices or users, configure access appropriately instead of relying on a hidden view or an inconspicuous button.

When to use separate dashboards or views

Separate views are useful when people have different tasks or when information belongs in distinct contexts. A household might keep everyday controls in an overview, room-specific controls in room views, and charts or diagnostic details elsewhere. This keeps the main screen focused without discarding information that is useful occasionally.

A separate dashboard can make sense when the audience or display is genuinely different—for example, a dedicated wall tablet or a simplified interface for another household member. It is not automatically better to create many dashboards: each one takes effort to maintain, and inconsistent layouts can confuse users. Start with a few views and split them further only when a clear need appears.

Frequently Asked Questions

What is the biggest mistake on a Home Assistant dashboard?
Showing too many entities and controls on one screen. Organize around common tasks and make less-used information available in a separate view.

How many cards should a dashboard have?
There is no ideal fixed number. Use enough cards to support the intended tasks, then remove items that add clutter without helping someone make a decision or take an action.

Should I make a separate dashboard for my phone?
Not necessarily. First check whether the existing views work well on the phone. A separate dashboard can help when the phone has distinct needs, but maintaining two layouts adds work.

Can a dashboard run automations?
A dashboard provides a user interface for viewing information and controlling Home Assistant. Automations are configured separately to respond to triggers and conditions. A dashboard control may let a person activate a relevant action, but it is not a substitute for automation logic.

Is hiding a card enough to protect a device?
No. Hiding a card changes what appears in a view; it does not by itself establish access permissions or secure the device. Use Home Assistant’s account and access settings for access control.

Why are some dashboard entities unavailable?
An entity may be unavailable because its device, integration, or connection is not currently reporting a usable state. Check the entity and integration status in Home Assistant before assuming the dashboard card itself is the cause.
