GL25B

[4noxx]

Maybe this can help you. After a few days, I can now control the GL25B:

sudo python3 lampe.py brightness 75
sudo python3 lampe.py temp 4400
sudo python3 lampe.py temp 2900
sudo python3 lampe.py temp 7000

import hid
import sys

VID = 0x0581
PID = 0x011d

def send_command(cmd_bytes):
    """Open HID device, send command and close"""
    device = hid.device()
    device.open(VID, PID)
    device.write(cmd_bytes)
    device.close()

def set_brightness(brightness):
    """Set brightness between 0-100%"""
    brightness = max(0, min(100, int(brightness)))
    # Build HID command with brightness value
    cmd = bytes.fromhex(
        f"ba70240000000077580182{brightness:02x}8c"
        + "00" * 32
    )
    send_command(cmd)
    print(f"✅ Brightness: {brightness}%")

def set_color_temp(kelvin):
    """Set color temperature between 2900K-7000K"""
    kelvin = max(2900, min(7000, int(kelvin)))
    # Convert kelvin to device value (e.g. 4400K → 44)
    val = kelvin // 100
    # Build HID command with color temperature value
    cmd = bytes.fromhex(
        f"ba70240000000077580183{val:02x}8c"
        + "00" * 32
    )
    send_command(cmd)
    print(f"✅ Color temperature: {kelvin}K (value: 0x{val:02x})")

def print_usage():
    """Print usage instructions"""
    print("Usage:")
    print("  sudo python3 lampe.py brightness <0-100>")
    print("  sudo python3 lampe.py temp <2900-7000>")
    print("")
    print("Examples:")
    print("  sudo python3 lampe.py brightness 75")
    print("  sudo python3 lampe.py temp 4400")

    if len(sys.argv) < 3:
        print_usage()
        sys.exit(1)

    cmd = sys.argv[1]
    val = int(sys.argv[2])

    try:
        if cmd == "brightness":
            set_brightness(val)
        elif cmd == "temp":
            set_color_temp(val)
        else:
            print(f"❌ Unknown command: {cmd}")
            print_usage()
            sys.exit(1)
    except Exception as e:

        sys.exit(1)
