Home Assistant Green

Home Assistant Green is the entry-level official hub from Nabu Casa, built to be the cheapest reliable way to run Home Assistant on dedicated hardware. Inside the small fanless case is a Rockchip RK3566 quad-core ARM processor with 4 GB of RAM and 32 GB of eMMC storage, with Home Assistant OS preinstalled. You plug in Ethernet and power, open a browser, and within minutes you have a fully local smart home controller — no account, no subscription, and no cloud dependency of any kind.

Home Assistant Yellow

Home Assistant Yellow is the official purpose-built hub from Nabu Casa, the company that employs the core developers of the open-source Home Assistant project. It pairs a Raspberry Pi Compute Module 4 with a carrier board designed specifically for home automation: Gigabit Ethernet, an M.2 slot for NVMe storage, two USB-A ports, and a Silicon Labs MGM210P radio module that handles Zigbee 3.0 and is Thread-capable for Matter ecosystems. It ships with Home Assistant OS preinstalled, so it boots straight into a fully local smart home controller with no account, no subscription, and no cloud dependency.

Shelly Plus 1

The Shelly Plus 1 is a miniature Wi-Fi relay from Shelly (Allterco Robotics) that installs behind an existing wall switch or inside a junction box, making ordinary lights, fans, gates, and garage doors smart without replacing any visible hardware. At roughly 42 by 36 by 17 millimeters it fits in standard wall boxes, its dry-contact relay switches up to 16 amps, and it accepts a wide range of supply voltages — 110 to 240 volts AC as well as low-voltage DC — which makes it useful well beyond lighting.
