Hardware accelerated graphics on the raspberry pi4 for a speedier KDS

Surfacing the right information at the right time in the right place is a difficult but essential task for any credible automation system.

I have been experimenting with the concept of a Home Assistant powered KDS for a few years now and have found that the refrigerator happens to be an especially good place to surface some information and device controls.

Yes, it's over-exposed and shot at an awkward angle but that's what it took to minimize glare!

This is a quick post for made in the hopes that some poor soul in the future will find it and save themselves some time.

Background

I’ve been experimenting with a few different ways to surface various home automation controls in the appropriate place and at a good time. One prototype host is deployed behind a small LCD under some cabinets in a high traffic area. This host is a raspberry pi 4 with a PoE hat. It boots a very stripped down version of Raspberry Pi OS into a web browser running in Kiosk mode.
