What is Home Assistant Green? Why skip cloud-based solutions?
Home Assistant Green is a local smart home hub produced by Nabu Casa. Unlike Apple HomeKit, Google Home, or Amazon Alexa, it does not rely on cloud servers; all your data is stored entirely within your home. This is particularly important for users in Hong Kong—no cloud subscription fees, no risk of privacy leaks, and it continues to function perfectly even if the internet goes down.

Unboxing and Installation: 5 Steps to Initial Setup
Step 1: Preparation
You will need: Home Assistant Green hub + Ethernet cable. The power adapter comes with a USB-C cable and supports Hong Kong's 220V standard, ready to use out of the box.
Step 2: First Boot
Connect the hub to your router using the Ethernet cable, plug in the power, and wait about 5 minutes for initialization. A solid green LED indicates the system is ready.
Step 3: Accessing the Setup Page
Enter homeassistant.local:8123 in your browser to access the setup wizard. After creating an account, the system will automatically detect smart devices on your network.
Step 4: Install the Official App
Download the official Home Assistant app on your iPhone or Android to control your home remotely.
Step 5: Connect Your First Device
Native support for Wi-Fi, Matter, and Thread. If you need to connect Zigbee devices, we recommend purchasing the Home Assistant Connect ZBT-2 USB adapter.
Must-Have Accessory: Home Assistant Connect ZBT-2
If you have Zigbee or Thread devices (such as Aqara, Nanoleaf, etc.), we strongly recommend adding the Home Assistant Connect ZBT-2. By plugging it into the USB port of your Green hub, you can directly control Zigbee and Thread devices, eliminating the need for brand-specific hubs and saving both cost and complexity.
