I now found out how to control i2c interface by issuing the commands i2cget and i2cset. I would like to be able to control the NO relay - and tried this from command line i2cset 0x6b 0x0b 0x00 - to turn off i2cset 0x6b 0x0b 0x01 - to turn on
I can read that the value changes - but nothing happens to the relay - it stays on ????
