  • GPIO 14 Fan Control (checkbox, Raspberry Pi, Advanced) — Uses GPIO 14 PWM to control a cooling fan. Takes effect on reboot; the fan’s temperatures are then set under Fan Temperatures below. A cape that declares its own fan in its device tree does not use this setting and removes it.
  • Fan Temperatures (dynamic section, shown only when a fan thermal zone is present) — Every thermal zone with a fan cooling device bound to it — from the setting above, a cape’s own device tree, or the Pi 5 active cooler — is rendered by PrintFanThermalSettings() as FanTrip_<zone sanitized>_<index> inputs, per zone (e.g. CPU, K16-Pro) with trip points sorted low→high (“Fan On Temperature”, “Fan Speed 2/3…”). Changes are written to sysfs immediately and re-applied at every boot by FPPINIT_Config, since trip points revert to their device tree values on boot. Reset to Defaults POSTs api/settings/fanThermal/reset to restore the hardware values. Stored in °C, displayed in °F when Temperature display units = Fahrenheit.
  • Status Display (dropdown via /dev/i2c-* check) — OLED/LCD on the Pi/BeagleBone I²C bus. Options: Disabled, 128×64 SSD1306 (normal/flipped/h-flipped), 128×64 2-color variants, 128×32 variants, SH1106/SH1107, SSD1327, PCF8574/PCF8574A 16×2/20×4 I²C LCDs, etc. Reboot required.

  • Prevent HDMI CEC at Boot (checkbox, Raspberry Pi except Pi 5) — Suppresses the initial CEC Active Source broadcast at boot that can wake connected TVs/projectors (e.g. Epson L210SF after a power outage, issue #2938). When enabled, fppinit adds hdmi_ignore_cec_init=1 inside a managed block in /boot/firmware/config.txt. Unlike hdmi_ignore_cec=1 it only suppresses the boot broadcast — the CEC plugin can still power the display on/off on demand. Hidden on Pi 5 (KMS/RP1, no firmware HDMI path) and any stale block is removed there. Reboot required.
  • FPPD Boot Delay (dropdown) — Wait after boot before starting fppd so slow switches/routers can come up and E1.31 multicast works. Options: 0–10s, 15/20/25/30s, 1/2/3/5 min, Auto (−1, wait until NTP/RTC time is valid or 5 min max). Not shown inside containers.
  • Override UUID (text, Advanced, pii) — Replacement UUID for FPP Connect dedup / stats / services instead of the CPU/serial-derived one. Reboot required.
