Thank you for your DS2482, it works well and the code is well laid out.
I just want to let you know that I made it a standalone module compatible with the adafruit_onewire.bus.OneWireBus interface so it can be used by other Adafruit 1wire drivers.

As you can see I gave you credits and linked to your project.
