Auto-boot and display a lovelace tab on Raspbian Buster?

I have two built in montiors in the wall with Raspbian Buster.
One running magicmirror and a calendar, the other one I plan to show a lovelace page.

So I need a way to:

  • On boot. Open a browser
  • Make the browser fullscreen
  • display the lovelace page, and authenticate automatically with Home-Assistant. I Understand IP-based no-auth is no longer supported.

Do it exist any guides on this or do anyone have recomendations on how i do this?

Chromium might be the best choise?

I’ve done similar and indeed used Chromium, here’s a guide to get you started:

There’s also a setting in DietPi to do similar if you’re using that.
