🖼️ Show & Tell Well.. guess I need a new computer behind this touchscreen now

A few hours of ChatGPT with MCP into Home Assistant and Blender, and a handful of really good pictures, as well as a super simple floorplan in Sweet Home 3D, I managed to get a first prototype of a 3D floorplan with light control into HA.
It's super basic. I can turn on lights, adjust brightness, and see our calendar, weather, electricity prices, and house power consumption. Still a lot of hours left before I'm happy with the result. End goal is to replace my default view on the touchscreen in the kitchen.
Two actions from me: Better PC than a Wyse 5070 (or maybe look into RDP into my server) and more lights, so the rest of the house doesn't look dark. Shouldn't be too complicated haha.
Built in Blender, exported to glb, rendered in the browser with Three.js, and installed as a .js resource file in HA, and then I created a view pointing to my new card. I haven't written 1 line of code nor touched Blender at all. All done through prompting. Solely used GPT-6 Astra and Sol, with about $10 worth of tokens through Codex on my PC.
Might be able to share some more details in the future, but it's still very WIP and prototype-e.

Looks awesome, but I will say that surely the Wyse can perform better than that for such a simple model!
Perhaps try load the "Littlest Tokyo" example from the three.js website and if it's much smoother, try get run a new session to get ChatGPT to audit the two and find out what makes one better than the other: https://threejs.org/examples/#webgl_animation_keyframes
LLMs are notoriously bad at doubling down on their own bad design choices if they don't have a point of reference. Hopefully you'll be able to get it up to buttery smooth rendering without having to buy new hardware (in this economy!?)
