Pi3 + add on board - Pi UPS+

  • Hi.
    I'm using LibreELEC on RPi3. I would like to add "UPS" solution to my RPi - Klik-Pi UPS+


    I'm totally noob in LibreElec. I try to install it like it was describe in manual Klik-Manual EN but no lack.
    I have no idea how to enable i2c interface on LibreElec and how to download program package.

    I will be very grateful for any help.
