I built a Tamagotchi that dies when my homelab goes down

My Mini PC hosts several homelab services, including Home Assistant, Jellyfin, Audiobookshelf, Calibre, Uptime Kuma, and more. It also hosts some local LLMs, and in recent weeks, one of these has been hogging so much RAM that it's brought down other services. I decided to set up a fun way to monitor my homelab using a cheap ESP32 board.
