First off, a huge thank you for creating such an amazing extension! Your work makes developing with AI models so much easier.

I have a feature request: Would it be possible to trigger loaded models via HTTP? This would be incredibly useful for local development, as it would allow seamless integration with custom scripts or applications without having to adjust the entire workflow.

Thanks so much for considering this, and keep up the great work!

In theory, I think main_loop.epd.Clear() should work, around line 368 in display.py -- but I haven't been able to get that to do anything.

Or better allow to set custom screen image :) then you can set empty :)
