In previous posts, I’ve explained how to use Tailscale’s MagicDNS and HTTPS certificate feature to generate a TLS cert for your Home Assistant install: Homeassistant Enable MagicDNS and HTTPS Certificates in Tailscale. That setup required you to reformat the TLS cert and copy it to the Home Assistant container… it wouldn’t be to much of a task to automate those actions, but fortunately there is now a superior method of applying and renewing a Tailscale cert for HASS (and many other self-hosted services).

It offers a feature called MagicDNS that enables you to access your resources using a domain name instead of an IP address. Additionally, you can use HTTPS certificates to encrypt traffic between clients and servers, ensuring secure communication. In this tutorial, we’ll explain how to enable MagicDNS and HTTPS certificates in Tailscale and how to add a TLS certificate to Home Assistant using Tailscale. The most practical benifit for using Home Assistant within a Tailscale network is that it removes the requirement for network port forwarding and exposing services publicly, whilst still allowing your devices to access it from outside your local network. This blog post aims to give you the starting stes required to setup MagicDNS and HTTPS certificates in Tailscale, create a certificate on your home server and install that certificate in a Home Assistant docker container. ...
