Fan Controller source published

ESPHome firmware for a WiFi PWM fan controller driving a spot-cooling hub over hot rack gear, surfaced as a first-class device in the home-automation stack.

Notable engineering

  • Firmware rather than an application — ESPHome on an ESP32 driving a PWM fan hub.
  • Spot-cools specific hot components in the rack instead of raising airflow across the whole enclosure.
  • Appears in the home-automation stack as a normal controllable device, so it is automated with the same tooling as everything else.
