Tailscale

In my previous post, I shared how to install Home Assistant OS (HAOS) inside a KVM on a Raspberry Pi 5. While having a powerful local server is great, it brings up a major question: How do you access it securely from the outside?

For this setup, I wanted to achieve two specific goals:

1. Enable a free and secure VPN for my mobile device (so I can surf safely on public Wi-Fi).
2. Gain seamless remote access to Home Assistant without exposing any ports to the internet.

The answer to both is Tailscale.
