How to Build a Smart Home in 3 Steps?

Step 1. Define Your First Scenarios

Don't try to automate everything at once. Three basic scenarios that deliver real value: motion-activated lights, water leak notification, heating on a schedule. Add new devices gradually.

Step 2. Choose a Hub and Protocol

Home Assistant + Zigbee — the universal choice: 3,000+ devices from any manufacturer, works without internet, open source. AI Home Server comes with a pre-configured Zigbee coordinator and Home Assistant — no setup from scratch required.

Step 3. Create Automations

Example basic automation: "Everyone left home → turn off lights, close water valves, lower heating." In Home Assistant this is 5 clicks in the visual editor or a few lines of YAML. More details in the setup guide.
