I only started this little project last week, but mix in some performance-enhancing AI and I think it's ready for some real-world beta testing by fellow Home Assistant enthusiasts.

The general idea...

--------------------------------------------------------
That old iPad gathering dust. The Android tablet mounted on the kitchen wall. The Fire HD you picked up for $30. HAven gives them a second life as always-on Home Assistant displays — no addons, no server-side code, no install. Just static files dropped into your HA www/ folder and a browser that can open a URL.

Inspired by the pixel-perfect philosophy of OpenHASP — itself built on LVGL, the embedded graphics library that brought beautiful UIs to microcontrollers. HAven borrows the same core idea: a fixed canvas, absolute widget placement, and JSON-driven config files. But instead of flashing firmware onto an ESP32, you point a browser at a URL.

But if you love your modern Lovelace dashboards and have no interest in resurrecting old hardware, this probably isn't for you.

Here's a sneak peek at one of my test dashboards - still lots to do, but it runs on an iPad 2 from 2011 that's been sitting in my drawer for years. If it works on that, it should work on most things.

I'm Hamilton-based so it'd be great to find some locals to test with, but anywhere in NZ works. Drop me a PM if you have some old tablets or smart TVs gathering dust and fancy giving it a spin.
