3. Fully custom: Home Assistant
If you want to build a fully custom dashboard without any constraints on the format, code, or integrations, you should consider using Home Assistant on the backend. There are a number of community plugins (e.g., Custom Header) that allow you to hide the default Lovelace UI components and activate Kiosk mode, the rest is basically on you and your CSS skills. You can get some inspiration here by at some of the best Home Assistant dashboards out there.
Have you built your own dashboard? What software are you using? Please feel free to share your projects in the comments section.
