So, inspired by and based on @rutman286’s scripts for link light scheduling for switches and Route10, and while waiting for a UI-driven scheduling, I’m unveiling a script for switching the Blue/White top-LED on and off and control color and brightness for APs.
A prerequisite might be that the LED-light is set to White in the UI, to release the system’s continuous control over the Blue channel channels. I already had it on White and haven’t checked if Blue would prevent this script. If so, there might possibly be a way to get around that too, but I haven’t dug into that to any extent.
It injects brightness levels for the different Blue and White channels (e.g., /sys/class/leds/white/brightness).
It works, at least, on AP6 Pro.
Set COLOR_CHOICE to integer 0-6 according to preferred colour and brightness (or off altogether, via 0, which doesn’t make much sense of course…)
#!/bin/sh
#
# AP LED scheduler with colour presets
# Set COLOR_CHOICE to a number (0–6) to pick the colour for ON
time.
COLOR_CHOICE=2 # 0=Off 1=Blue 2=White 3=Both 4=Dim-blue 5=Dim
-blue+white 6=Dim-white
# --- Map number to blue/white values ---
set_color_values() {
case "$COLOR_CHOICE" in
0) # Off
LED_BLUE_ON=0; LED_WHITE_ON=0 ;;
1) # Blue only
LED_BLUE_ON=255; LED_WHITE_ON=0 ;;
2) # White only
LED_BLUE_ON=0; LED_WHITE_ON=255 ;;
3) # Both (pale blue)
LED_BLUE_ON=255; LED_WHITE_ON=64 ;;
4) # Dim blue
LED_BLUE_ON=64; LED_WHITE_ON=0 ;;
5) # Dim blue + white
LED_BLUE_ON=64; LED_WHITE_ON=32 ;;
6) # Dim white
