I discovered Audiobookshelf a while back and thought it would be great to run it as an add-on within Home Assistant. I know Kevin released an add-on for Audiobookshelf, but it was missing an essential feature for me: secure access via HTTPS.
Audiobookshelf doesn't have any settings to use HTTPS instead of HTTP, so I've created a new Audiobookshelf add-on with embedded Nginx.
With this new add-on, you can run Audiobookshelf in Home Assistant and access it via HTTP or HTTPS by simply enabling a flag in the settings. There’s no need to install the Nginx Proxy Manager add-on separately; you can use the SSL certificates you already have in Home Assistant — for example, those from Let’s Encrypt.
You’ll find the add-on repository at https://codeberg.org/albertogonzalez/ha-addons
I’ve been using it myself for over a month without any problems. If you try it and notice anything unusual, I’d love to hear your feedback.
