To get started with Home Assistant, install Home Assistant OS on a dedicated Home Assistant Green or a Raspberry Pi 4 or 5, finish onboarding, add one integration, and build a small automation and dashboard around a useful task. Automations respond to events, dashboards put controls and information on screen, and scripts let you reuse a sequence of actions. You can create your first automation in the visual editor without coding. Home Assistant runs on hardware in your home; the official beginner guidance says a cloud server or hidden subscription is not required and that many people can reach a working smart home in about an afternoon.
What do you need to get started with Home Assistant?
You need a host that runs Home Assistant, access to its web interface or app, and at least one compatible device or service to bring into it. The simplest path for many beginners is Home Assistant OS: it is the recommended installation type for most users and is available preinstalled on Home Assistant Green. If you want to use hardware you already own or build a DIY system, the official installation guide lists Raspberry Pi 4 or 5 as a route.

You can begin with a single room or one outcome—such as turning on a light when motion is detected—then expand after that basic setup works. That small start also makes it easier to spot whether a problem is with the device, its integration, or the automation.
Choose a host that fits your setup comfort
| Host path | What it involves | Best fit | Trade-off |
|---|---|---|---|
| Home Assistant Green | A dedicated appliance with Home Assistant OS preinstalled. Connect power and Ethernet, then use the app or web app to begin setup. | People who want a ready-to-use hub and minimal installation work. | It is a separate device to purchase. The Home Assistant/Nabu Casa page version 2026.10.4 lists a recommended MSRP of $199 / €179; regional prices, taxes, and retailer pricing vary. |
| Raspberry Pi 4 or 5 | Install Home Assistant OS on a Raspberry Pi. The official guide lists the Pi, a power supply, a microSD card, and an Ethernet connection as requirements. | People who already own a suitable Pi or prefer assembling and configuring their own host. | You supply and prepare the hardware rather than using a preinstalled appliance. The required parts are listed in the installation guide; a particular retailer price is not established here. |
| Home Assistant Container | Run the Container installation in an environment such as Docker. | People comfortable with Docker, the Linux command line, and managing updates themselves. | It does not include Home Assistant OS apps and lacks out-of-the-box support for some integrations, including Thread and Z-Wave, according to the official installation comparison. |
For a first installation, Home Assistant OS avoids the additional administration associated with Container. The Container route is not simply another name for the same setup: it comes with different maintenance responsibilities and does not provide the Home Assistant OS apps. Choose it when that control and administration model is intentional, not just because it sounds more flexible.

Know what optional hardware and services are for
Home Assistant Green can detect devices after setup, but a specific device’s compatibility depends on that device and its integration; do not assume every smart-home product works merely because Home Assistant has many integrations. The Home Assistant/Nabu Casa product page, version 2026.10.4, says there are more than 1,000 built-in integrations supporting hundreds of thousands of smart devices and online services, with more added by the community.
A Home Assistant Connect ZBT-2 is an optional accessory for a direct Zigbee or Thread radio connection when your devices need one. The product information describes Thread support as under development, so do not treat that as a guarantee that a particular Thread setup is ready or supported. Home Assistant Cloud is also optional; it is relevant to seamless Google Home and Amazon Alexa integration, but it is not a prerequisite for starting with Home Assistant.
How do you finish setup and add your first integration?
After the host is installed, complete onboarding and connect a device or service through an integration. An integration brings a device or service into Home Assistant; its entities are the individual controls, sensors, or functions you can use in a dashboard or automation.
- Start the host. For Green, connect power and Ethernet, then open Home Assistant in the app or web app. For a Raspberry Pi installation, prepare the Pi, power supply, microSD card, and Ethernet connection as described by the official installation guide.
- Complete onboarding. Follow the setup flow presented by Home Assistant. Once it is running, use the app or web interface to work with the system.
- Add a device or service. Add the integration for something you actually want to control or monitor. Green’s product documentation says Home Assistant can detect devices, but you should still confirm that the device or service you have is supported.
- Check the entities it provides. Identify the useful individual controls or readings—such as a light control, motion sensor, or temperature reading—rather than trying to organize every available entity at once.
- Test one outcome. Confirm that the device can be seen or controlled in Home Assistant before building a more complicated automation around it.
This order isolates problems. If a sensor does not appear as expected, adding several automations at the same time makes it harder to tell whether the issue is the integration or the automation logic. Start with one room, one integration, and one result you can verify.

How do you create your first Home Assistant automation?
Create a small event-driven flow in the visual automation editor: choose a trigger, add a condition only if needed, and select an action. Home Assistant’s documentation says the editor lets you choose devices and entities without coding.
- Open the editor: go to Settings > Automations & scenes > Create automation > Create new automation.
- Choose a trigger. Pick a clear event, such as motion being detected, a door opening, or sunset. A trigger starts an automation at a particular moment; it is not a continuing instruction that fires repeatedly just because a state remains true.
- Add a condition only when the action needs a gate. For example, you might want an action only when someone is home or only after sunset. A condition checks whether the required state is true when the trigger starts the run.
- Add one action. Choose the work Home Assistant should do, such as turning on a light, sending a notification, or activating a scene.
- Save and test. You can run the automation manually or wait for its trigger event. Check that the selected action produces the outcome you intended.
Understand the order of execution
An automation follows a simple order: trigger, optional conditions, then actions. The trigger determines when a run begins. Conditions decide whether the run proceeds based on the state at that start moment. Actions perform the requested work if the run passes the conditions.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
This timing distinction matters. If a trigger happens while a condition is false, the automation does not sit and wait for the condition to become true later. Likewise, a condition is not itself a trigger: a state becoming true later does not start the automation unless an appropriate trigger is configured for that event. If the desired behavior is “do this when the condition changes,” select a trigger that represents that change, then use conditions to gate the resulting run as needed.
After a run, open its trace to see which trigger started it and the path it took. A trace is the first place to look when an automation did not run or did something unexpected: it can help distinguish a missing trigger from a condition that prevented the actions.

Which automation mode should you choose?
Automation mode determines what happens when another trigger arrives while a previous run is still active. Home Assistant provides Single, Restart, Queued, and Parallel modes; choosing one deliberately prevents overlapping-run behavior from becoming a surprise.
| Mode | What happens when a new run is triggered | Useful when |
|---|---|---|
| Single | The new run is ignored while an existing run is active, and Home Assistant logs a warning. | A simple light automation or other flow where another start during the current run should not launch a second copy. |
| Restart | The active run is stopped and a new run begins. | A “latest event wins” notification or timer, where fresh input should replace work already in progress. |
| Queued | New runs wait and execute in order. | Actions that must not overlap and should be processed sequentially. |
| Parallel | A new run starts independently while the earlier run continues. | Events that each need independent handling rather than waiting for one another. |
For example, if an automation sends a notification and a later event should supersede the pending one, Restart may suit that intent. If each event must be handled in sequence, Queued is a better conceptual fit. The important question is whether a new event should be discarded, replace the current run, wait its turn, or proceed independently. Put that intention in the automation description so it is clear to whoever edits the flow later.
How should you organize a Home Assistant dashboard?
A dashboard is the at-a-glance view of your home. Organize it as a dashboard containing views, with cards inside each view; start with a small number of high-value controls and readings, then add focused views as your needs grow.
Home Assistant supports visual dashboard building with drag and drop, so you can arrange useful information without writing code. A practical first view might put the main room controls together with a current temperature or presence reading, plus a shortcut to a frequently used script. Avoid placing every entity on the first screen: more detail is easier to navigate when it has a dedicated view.

Choose a view type for the information
| View type | When it fits |
|---|---|
| Sections | The default view type and a sensible starting point for arranging a general-purpose dashboard. |
| Masonry | An alternative view layout when its arrangement better suits the content you want to display. |
| Panel | A view type to consider when the page is centered on a particular panel-style presentation. |
| Sidebar | A view type for a layout that uses a sidebar arrangement. |
Views control layout, so the decision is about how to present a group of related information—not a different way to create automations. Use one main view for frequent controls, then separate room status, energy, or security information into additional views when the dashboard would otherwise become crowded.
Select cards according to their job
| Card purpose | Examples | Typical use |
|---|---|---|
| Control | Button, Entity, Tile, Area | Expose a control or an area of the home for convenient access. |
| Data | Sensor, History graph, Statistic, Statistics graph, Energy | Show a current reading, history, statistics, or energy information. |
| Logic and filtering | Conditional, Entity filter | Show content conditionally or filter which entities appear. |
| Grouping | Grid, stacks | Arrange multiple cards together in a structured layout. |
Choose cards by the task a person needs to perform or the information they need to scan. For a quick daily screen, a few controls and a small set of current readings are usually more useful than a comprehensive inventory. The extra views can hold less frequently used detail without hiding the actions people reach for most.

What is the difference between a Home Assistant automation and a script?
An automation starts from a trigger; a script is a saved sequence that runs when something calls it. Use an automation for event-driven behavior and a script when the same sequence should be reusable from a dashboard, Assist, an automation, or another script.
| Automation | Script | |
|---|---|---|
| Starts by itself? | Yes, when its configured trigger starts a run. | No. It has no triggers and runs when started by a caller. |
| Best role | Respond to an event, apply optional conditions, and perform actions. | Package a reusable sequence of steps that a person or another flow can call. |
| Where it can be used | Configured to react to its triggers. | From a dashboard, Assist, an automation, or another script. |
| Can it accept caller-provided values? | Not established here as the distinguishing feature. | Scripts can expose fields so a caller can supply values such as a delay or target light. |
To create a script, go to Settings > Automations & scenes > Scripts > Create script. A sequence such as “Good morning,” “Leaving home,” or “Movie mode” is a natural candidate if more than one place should be able to invoke it. If a few actions are used only once inside a particular automation, keeping them there avoids extracting a reusable component that has no other caller.
Best Value
- KEEP YOUR PROCESSOR COOL: The busier a processor gets the more it heats up, leading to sub-optimal performance. To prevent this common issue, this kit includes an aluminum alloy case with a pre-installed fan. The aluminum alloy actively draws the heat from the pi board, while the fan further cools the board and case. These cooling mechanisms will help push the limits of your processor and increase its flexibility.
- SIZABLE RAM: This Raspberry Pi 4 comes equipped with 4GB of RAM, which is the same amount of RAM or more RAM than many mainstream laptops contain. With 4GB of RAM, your processor will be capable of running retro gaming setups and common computer applications, media players, and much more!
- SIMPLE TO TURN ON & OFF: This kit includes a USB-C Raspberry Pi 4 compatible power supply with an easy-to-use on/off switch that was designed specifically for the Raspberry Pi 4 model to streamline processing.
- IMPROVEMENTS FROM PREVIOUS MODELS: This latest model of the Raspberry Pi 4 offers groundbreaking increases in processor speed, multimedia performance, connectivity, memory, and more! The desktop performance of this model is comparable to entry-level x86 PC systems.
- VERSATILE USE: The Raspberry Pi may have a small processor, but it is a highly adaptable little computer that can replace your desktop PC. Its functions range from practical to nostalgic since it can power an ad-blocking server as easily as it can power an outmoded gaming setup. Other uses include but are not limited to printing from non-wireless printers, playing media, making time-lapse videos, and building multiplayer network game servers and motion-capture security systems.
How scripts can grow beyond a fixed sequence
In YAML, scripts are sequences of action maps. They can set an alias, call an action with a target and data, activate a scene, and branch using if/then/else. A script can also expose fields, which lets a caller provide an input such as a delay or which light to target. That makes a script useful not only as a fixed “mode” button, but also as a reusable action whose details can vary by caller.
You do not need YAML to make a first script in the interface. Begin with a simple sequence, then consider fields or branching only when a real use case calls for them. Keeping the script’s purpose clear makes it easier to decide whether an action belongs in the script or should remain specific to one automation.

Keep the first project small enough that you can verify each piece: the integration exposes the right entity, the trigger represents the event you care about, conditions gate the run at the right time, and the action changes the desired device or service.
- Start with one result. Pick one room or one outcome, rather than adding many integrations and automations simultaneously.
- Make the trigger observable. Choose a recognizable event such as motion, a door opening, or sunset, then test whether Home Assistant sees it.
- Use conditions narrowly. Add only a state requirement that changes whether the action should happen. Remember it is evaluated when the trigger starts.
- Choose a run mode based on overlap. Decide what a second trigger should do if the first run has not finished.
- Keep the dashboard selective. Put the most-used controls and readings in the main view and move additional detail into focused views.
- Extract only repeated work. A script is most valuable when another caller can reuse it.
- Use traces when behavior surprises you. Check the trigger and path of an actual run before changing multiple parts of the automation.
Home Assistant’s breadth makes it possible to grow a system substantially, but it does not mean the first setup should attempt to cover the whole home. A working single-room example gives you a known pattern to adapt while keeping each new integration and behavior understandable.
Frequently Asked Questions
Does Home Assistant keep running if my internet connection goes down?
Home Assistant runs on hardware in your home, and its beginner guidance says a cloud server is not required. The behavior of an individual device or service during an internet outage depends on that device and integration; this setup information does not establish the offline behavior of every product.
Do I need Home Assistant Cloud to use Home Assistant?
No. Home Assistant Cloud is optional; it is relevant if you want seamless Google Home or Amazon Alexa integration, but it is not needed to create local automations, dashboards, or scripts.
