I’m sure most owners of these BTT Panda Touch devices have been looking at other uses after the drama with Bambu Labs. I’ve used espHome to make a dashboard for my HA:
I recommend backing up your BTT firmware using esptool or the recovery software on the Panda Touch github repo before flashing in case something goes horribly wrong. You will need to initially flash esphome using the USB C port that is on the back of the magnetic mounting dock.
Here is a basic config to get you started with making your own dashboard. You can use this to test the display and touch screen as well. You should be presented with this test screen:
Then it’s just a matter of building your own custom LVGL dashboard! With any luck though this will be made easier with ESP Screens, providing its possible to support the board.
