DimDash turns your iPad into a beautiful, always-on smart home dashboard with intelligent auto-dimming, device display controls, and full-screen kiosk mode for wall-mounted setups. Point DimDash at any Home Assistant, Grafana, Dashy, Homarr, Glance, Node-RED, or Flame dashboard and walk away. When you stop interacting with the screen, DimDash smoothly dims the display so it does not burn in or blast light across the room at night. Touch anywhere to wake it instantly. How it works DimDash loads your dashboard URL in a full-screen web view. An idle timer starts after your last interaction. When it expires, a smooth overlay fades in to dim the display. Touch the screen and the overlay fades out with your dashboard exactly where you left it. Device display controls DimDash can keep your device awake while the app is open so your wall panel does not lock. You can also enable DimDash Brightness to apply a chosen device brightness whenever the app is active. Dashboard customization Hide Home Assistant header or sidebar chrome with built-in kiosk URL controls. Use opt-in JavaScript Injection snippets to hide common nav bars, prefer dark mode, disable text selection, hide scrollbars, or add your own validated script that runs after the dashboard loads.
