If you are looking to build a smarter home without relying on multiple apps, cloud platforms or complicated DIY hardware, Home Assistant Green is one of the easiest ways to get started.
Home Assistant Green is a dedicated smart home hub designed to run Home Assistant straight out of the box. Instead of installing Home Assistant on a Raspberry Pi or building your own server, Green comes preconfigured and ready to use.
But what can you actually do with it?
In this guide, we break down what Home Assistant Green can control, how it works, what you can connect to it, and why it has become such a popular choice for smart homes.
What Is Home Assistant Green?
Home Assistant Green is dedicated hardware designed specifically for running Home Assistant.
Setup is designed to be simple:
- Connect the power supply.
- Connect the Ethernet cable to your router.
- Open the Home Assistant app or web interface.
- Follow the setup process.
Once running, Home Assistant begins detecting compatible smart-home devices and services on your network.
Unlike many proprietary smart-home hubs, Home Assistant is designed to bring devices from different manufacturers and ecosystems together in one place.
1. Control Your Smart Home From One Dashboard
One of the biggest benefits of Home Assistant Green is being able to control compatible devices from a single dashboard.
Instead of opening one app for your lights, another for your air conditioner, another for your sensors and another for your smart plugs, Home Assistant can bring supported devices together into one interface.
You can build dashboards for things such as:
- Smart lights and switches
- Smart plugs
- Temperature and humidity sensors
- Motion and presence sensors
- Door and window sensors
- Blinds and curtains
- Air conditioning
- Energy monitoring
- Cameras and security devices
- Media players
- Smart locks
- Weather information
Home Assistant currently offers more than 1,000 built-in integrations, supporting a very large range of devices and online services.
2. Create Powerful Automations
Home Assistant Green is much more than a remote control for your devices.
Its biggest advantage is automation.
You can create rules that allow your home to react automatically to conditions, schedules, sensors and other devices.
Example: Automatically Turn Lights On
You could create an automation that:
- Detects movement in the hallway after sunset
- Turns the hallway lights on automatically
- Sets them to a lower brightness overnight
- Turns them off when no movement has been detected for several minutes
Example: Temperature-Based Automation
You could also:
- Monitor room temperature
- Turn a fan on when the room gets too warm
- Turn it off automatically once the temperature drops
Example: Leaving Home
A single automation could:
- Turn off selected lights
- Turn off appliances
- Close compatible blinds
- Arm supported security devices
- Notify you if a door or window was left open
These automations can combine devices from different manufacturers, which is one of the biggest advantages of Home Assistant.
3. Connect Devices From Different Smart Home Brands
Many smart homes gradually become a collection of different ecosystems.
You might have Apple HomeKit devices in one room, Google Home devices elsewhere, a few Wi-Fi switches, Zigbee sensors and perhaps Samsung SmartThings devices.
Home Assistant is designed to bring many of these systems together.
According to Home Assistant, it can work alongside existing:
- Apple HomeKit setups
- Google Home
- Amazon Alexa
- Samsung SmartThings
This means you do not necessarily need to replace your entire smart home when moving to Home Assistant.
You can gradually migrate devices and automations over time.
4. Control Wi-Fi and Ethernet Smart Devices
Home Assistant Green connects to your network using Gigabit Ethernet.
Compatible Wi-Fi and Ethernet smart-home products can therefore communicate with Home Assistant through your local network.
This can include products such as:
- Wi-Fi switches
- Smart plugs
- Energy meters
- Smart air-conditioning controllers
- Network cameras
- Media devices
- Smart appliances
Compatibility depends on whether Home Assistant has an integration available for the particular product or ecosystem.
5. Add Zigbee Devices
Home Assistant Green does not have a built-in Zigbee radio.
However, Zigbee support can easily be added using a compatible USB radio such as the Sonoff ZBdongle.
Once a Zigbee radio is connected, Home Assistant Green can become the central controller for compatible Zigbee devices, including:
- Motion sensors
- Door and window sensors
- Temperature sensors
- Smart switches
- Smart plugs
- Lights
- Buttons
- Blind motors
This can allow you to reduce your dependence on separate manufacturer-specific Zigbee hubs.
6. Use Matter Devices
Home Assistant Green supports Matter.
Matter devices operating over Wi-Fi or Ethernet can work with Home Assistant once the Matter integration and Matter Server are configured.
For Matter over Thread devices, you also need a Thread Border Router on your network.
You may already have a compatible Thread Border Router through certain Apple, Google or Amazon products. Alternatively, Home Assistant Green can be expanded with a Thread-capable radio such as Home Assistant Connect ZBT-2.
This makes Green a useful foundation for both current smart-home devices and newer Matter-compatible products.
7. Add Z-Wave Support
Z-Wave is another popular smart-home protocol, particularly for sensors, switches, locks and security products.
Home Assistant Green does not include a built-in Z-Wave radio, but its USB ports allow compatible Z-Wave hardware to be added.
This means one Home Assistant Green installation can potentially manage:
- Wi-Fi devices
- Ethernet devices
- Zigbee devices
- Z-Wave devices
- Matter devices
- Thread devices
The exact combination depends on the radios and integrations you add.
8. Monitor Your Home's Energy Use
Home Assistant includes energy-management features that allow compatible energy-monitoring devices to feed consumption data into one dashboard.
Depending on the equipment installed in your home, you could monitor:
- Whole-home electricity consumption
- Individual circuits
- Solar generation
- Battery usage
- Individual appliances
This can help you understand where electricity is being used and identify opportunities to reduce unnecessary consumption.
9. Keep More of Your Smart Home Local
Privacy and local control are major parts of Home Assistant's design.
Home Assistant states that your smart-home data is stored locally and that your Home Assistant system can continue operating even if your internet connection is unavailable.
This does not mean every third-party smart device will work without the internet. Some manufacturer integrations still rely on external cloud services.
However, devices and integrations that support local communication can continue operating locally through Home Assistant.
For many users, this is one of the biggest differences between Home Assistant and fully cloud-dependent smart-home platforms.
10. Build Custom Smart Home Dashboards
Home Assistant allows you to create dashboards suited to your household.
For example, you could create:
- A wall-mounted whole-home control panel
- A simple dashboard for family members
- A security dashboard showing doors, locks and cameras
- An energy dashboard
- A climate-control dashboard
- A tablet dashboard for the kitchen or living room
Different users can access Home Assistant from phones, tablets or computers.
11. Use Voice Control
Home Assistant can also integrate with voice-control systems.
You can continue using compatible ecosystems such as:
- Google Assistant
- Amazon Alexa
- Apple ecosystems
Home Assistant also has its own expanding voice ecosystem.
For users wanting straightforward integration with Google Home and Amazon Alexa, Home Assistant recommends its optional Home Assistant Cloud subscription.
12. Build Automations Across Different Brands
This is where Home Assistant becomes particularly powerful.
Your automation does not necessarily care which manufacturer made each device.
For example:
A Zigbee motion sensor detects movement → a Wi-Fi light turns on → a Matter smart plug activates → a notification appears on your phone.
As long as each device can communicate with Home Assistant, they can potentially participate in the same automation.
This allows you to choose products based on their features rather than being locked into one manufacturer's ecosystem.
