Using a secure, peer‑to‑peer mesh VPN by using WireGuard to exchange keys via a central coordination server and configure lightweight, encrypted tunnels that work seamlessly through NATs and firewalls. I decided to implement this so that our Home Assistant could be accessed from outside of our home network and still be secure. The added bonus of being able to access my personal Plex Server from outside without using Plex's own relay has also been a nice thing to have, as it's less strain on their servers and more privacy for me. A future project I would like to get to is linking this up so I can use my DNS filtering on the Raspberry Pi from outside my home network, reducing unwanted data being used up. Update 27/04/2025) I have since installed Tailscale on my Home Assistant via an Add-On so that I can connect to it on my Mini-PC.
