Home Assistant is free, open-source software that runs your smart home on your own hardware, like a Raspberry Pi or the official Home Assistant Green. It brings thousands of brands together in one place and works without any cloud.

The good news: Because Home Assistant runs on your own hardware and its code is open, no company can switch it off. Even if the foundation stopped tomorrow, your setup would keep running and anyone could keep developing the software. By 2025 it was running in more than 2 million homes.
The bad news: It takes more effort than a normal smart home app, and the project moves fast, so an update can sometimes change or break an integration. Old hardware also gets dropped: owners of a first or second Raspberry Pi had to move to new hardware to keep getting updates.
If you own Home Assistant
- Make regular backups. Home Assistant can create them automatically, so you can restore everything on new hardware.
- Read the release notes before big updates, especially the part about breaking changes.
