What it is

The Home Assistant Green represents a significant shift for the Nabu Casa ecosystem, offering a pre-configured hardware solution that removes the technical barriers usually associated with the platform. Instead of sourcing a Raspberry Pi and flashing SD cards, users simply connect this compact, fanless unit to their router. The hardware is optimized for the Home Assistant OS, providing a stable environment for managing thousands of supported devices across various brands without relying on the cloud. Under the hood, the device balances efficiency with capability, utilizing a quad-core processor and 4GB of RAM to handle complex automation logic. While it lacks built-in Zigbee or Z-Wave radios, the two USB ports allow for easy expansion via dongles. This design choice keeps the initial cost lower while allowing users to choose the specific wireless protocols they need. The focus here is on data privacy and local execution, ensuring your smart home stays functional even if your internet connection drops.

Ravvy AI insight

At $219, you are paying a premium for convenience and official support compared to a DIY Raspberry Pi build. However, the included 32GB eMMC storage is significantly more reliable than standard SD cards, which often fail under the high write-load of smart home databases. If you plan on running heavy video processing or dozens of complex add-ons, you might eventually hit the ceiling of the 4GB RAM, but for standard household automation, it is a perfectly balanced starter hub.

Ownership tips

tip

Add a SkyConnect Dongle

Since the Green lacks internal radios, pair it with a Home Assistant SkyConnect USB stick. This adds Zigbee and future Thread support, allowing you to connect most smart bulbs and sensors directly.

care

USB Expansion Power

If you plan on connecting multiple high-power USB devices, consider using a powered USB hub. This prevents the Green's power supply from being overloaded and ensures stable performance for your radios.

Frequently asked questions

Does it support Zigbee or Z-Wave out of the box?

No, the Home Assistant Green does not have these radios built-in. You will need to purchase separate USB dongles to communicate with Zigbee or Z-Wave devices.

Is there a monthly subscription fee?

Home Assistant itself is free and open-source. While there is an optional Nabu Casa cloud subscription for easy remote access and voice assistant integration, it is not required for the hub to function.

Can I upgrade the internal storage or RAM?

The RAM and eMMC storage are soldered to the board and cannot be upgraded. However, you can expand storage for backups or media using the available USB ports.

What happens if my internet goes down?

Because the Home Assistant Green processes your automations locally, your home will continue to function. Only features that explicitly require the cloud, such as external weather data, will be affected.

Where can you buy the Home Assistant Green?

Home Assistant Green is sold through Amazon, and Nabu Casa also lists it through its own site and major retail partners. The buy link on this page goes straight to the current Amazon listing, which is where stock and pricing update most often.
