Home Assistant Green, a smart home hub with the HA system pre-installed
Home Assistant Green is the official, easiest, and most reliable way to start building your local smart home. Designed by Nabu Casa — the team behind the Home Assistant system — this "plug-and-play" hub comes with the Home Assistant OS pre-installed. It operates entirely locally and does not rely on cloud services, ensuring total privacy, zero-latency performance, and continuous operation, even if your internet connection goes down.
Key Features
-
Plug & Play Setup: Skip complicated server installations. Just plug in the power and a gigabit ethernet cable, open your browser, and the setup process will begin immediately.
-
100% Local Control: Your smart home data stays physically in your home. No forced cloud subscriptions are required to run your critical automations.
-
Silent and Energy Efficient: The fanless design consumes less than 3 W of power under load. The heavy anodized aluminum base also serves as a massive heatsink, keeping the system cool and completely silent.
-
Hardware Expandability: Easily add support for Zigbee, Z-Wave, Matter, Thread, or Bluetooth by plugging a USB radio dongle (such as SONOFF Dongle Plus or SMLIGHT adapters) directly into the USB port.
-
Universal Compatibility: Acts as a single bridge for hundreds of thousands of devices from various brands, such as Shelly, Sonoff, Aqara, Apple HomeKit, Google Home, and Philips Hue.
