    Dear mshettha,
    Sorry for the late reply.
    Sorry, this device doesn't support fan speed control. Using node-red to control screen brightness is theoretically possible (you'll need to test it to be sure), and we don't have a tutorial yet, so you'll need to figure it out yourself.
    Sorry for the inconvenience .
    Best regards,

  • Hi Jennie,
    Apart from node-red. Can I do fan speed control and screen brightness by command line?
    Thank you,

    The instructions are all here. To locate this folder , you can use this command:
    sudo find /usr -name "scripts"


    Thanks! Have a good day!

  • Dear Jennie,
    Many thanks for sharing, I found the "scripts" folder. I have have tried to adjust screen brightness by using command "python brightness.py 100 screen". But the screen brightness is not change. Please give me some example in using this command.
    Please also give me the example command to control CPU fan speed as well.
