Self-host Home Assistant on a VPS

Why self-host Home Assistant?

Home Assistant keeps your smart home working without clouds, and a VPS can host the core or remote access.

How to install Home Assistant

1. 1

   Provision a VPS

   Choose a plan with room for your data as well as the app.

2. 2

   Install the stack

   Install Python (or HAOS container).

3. 3

   Deploy the application

   Follow the project’s official install guide for your distribution.

4. 4

   Enable HTTPS

   Serve it on your own domain behind a reverse proxy with a certificate.

5. 5

   Back it up

   Schedule a database dump plus a copy of any uploaded files to an off-box location.

Practical tips

• Give Home Assistant its own database user with rights only on its own schema.
• Reverse-proxy Home Assistant and terminate TLS at the proxy so certificates are managed in one place.
• Take a VPS snapshot before major upgrades so you can roll back cleanly.
• Keep Home Assistant patched — most self-hosting incidents are unpatched software.
