How it works

Automations can be as simple as turning lights on at sunset or as complex as adjusting heating based on who is home and what the weather is doing. Dashboards show every device in one place, and the mobile app gives you control from anywhere.

The software is free and open source, with an optional cloud subscription at $6.50 a month for remote access and voice assistant features. Home Assistant is the best choice for people who want a private, flexible smart home, though setup needs some technical confidence.
