Truth be told, while I had known about ESPHome while working on this project, for some reason, I just felt the urge to hack together my own firmware. It might've been because my early testing was done via an old Arduino Uno board, and I must've figured that I might as well port the sketch over to the ESP32 once I had it working. (I'm general though, I will say that LLMs can totally write bespoke one-off firmwares like this, and I don't feel too bad about it, given that it's running entirely within my LAN, and will never actually get "productized")
