How do you control the lid visible LED's on the M1 enclosure when using M404 and Muron ?
When using the Monitor One, the LED on the top cover is the system LED and the two side user LEDs are controlled by the ADP8866 I2C PWM controller.
When using the M1 Enclosure all three RGB LEDs controlled by an ADP8866 I2C PWM controller. It is connected to the I2C bus (address 0x27). You'll need to use an ADP8866 library to control the LED colors; you can use the one from the Monitor Edge firmware in the lib directory, or a different one, if you prefer.
