How much RAM does Home Assistant need?

Plan on 2 GB for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so Home Assistant plus your other workloads fit in RAM with room to spare.

Automation

Open-source home automation that runs locally.

Control and automate smart-home devices with local processing and hundreds of integrations.

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

1
Provision a VPS
Choose a plan with room for your data as well as the app.
2
Install the stack
Install Python (or HAOS container).
3
Deploy the application
Follow the project’s official install guide for your distribution.
4
Enable HTTPS
Serve it on your own domain behind a reverse proxy with a certificate.
5
Back it up
Schedule a database dump plus a copy of any uploaded files to an off-box location.

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.
