BC24 I2C configuration.

I'd like to move my BC24 boards to ESPHome.   I'm a bit of a noob when it comes to this, but one thing that sticks out when I review the ESPHome docs is that it needs to know the I/O configuration for the various devices.   I looked at the BC24 docs, and I can't see what I2C address the BC24 LEDs are at.   Did I miss anything?

Thanks,
Eric
