Everything is controlled via HTTP requests. Endpoints:

GET 127.0.0.1:21371/set/{mode}/{r}/{g}/{b} - Sets color for mode GET 127.0.0.1:21371/get/{mode} - Gets color for mode in {r}:{g}:{b}\n format

With mode being:

• charging, meaning device charging and below 90% battery capacity
• low_bat, meaning device having battery capacity between 0 and 20%
• full, meaning device having battery capacity of at least 90%
• normal, covering all other cases

And r, g and b being RGB values between 0 and 255.

Keep in mind that all mode values are for a case with 100% brightness, when the brightness of main display is lowered, the brightness values get scaled accordingly.
