IR Remote Power Button

Reset Power Button on IR Remote

This resets the power button on the IR remote to work properly

i2cset -y 1 0x1a 0xaa 0x00 0xff 0x39 0xc6 i

# Or for V3 case (pi 5)
i2cset -y 1 0x1a 0x82 0x00 0xff 0x39 0xc6 i

Disable Power Button

This sets the power button to respond to a random IR code

i2cset -y 1 0x1a 0xaa 0x01 0x23 0x45 0x67 i

# Or for V3 case (pi 5)
i2cset -y 1 0x1a 0x82 0x01 0x23 0x45 0x67 i
