Home Assistant is an open-source, locally-run smart home automation platform that aims to integrate smart devices across different brands and protocols, providing unified monitoring, control, and automation solutions. The core is local control and privacy protection.
Offers multiple deployment options: you can use dedicated hardware such as Home Assistant Green/Yellow, or install on DIY devices like Raspberry Pi, and it also supports deployment on common platforms such as x86-64, Linux, macOS, Windows.
Supports over 3,300 device integrations across brands including Mi Home, Haier, Ecovacs, and continues to expand the certified device ecosystem through protocols like Matter and HomeKit.
Basic device integration and automation setup can be done via the graphical user interface, suitable for regular users; advanced customization and extensions (such as using ESPHome) may require some technical learning, with the community offering rich guides.
All data processing and storage occur on the user's local devices, not relying on cloud servers, fundamentally safeguarding user data privacy and security.
The official options include out-of-the-box Home Assistant Green, extensible Yellow, and the upgraded smart home gateway Connect ZBT-2. Users can also install on their own hardware such as Raspberry Pi.
