My reason for wanting to use the 1-wire protocol is that we are currently monitoring/logging a 1-wire bin temperature setup and it would be nice to emulate the 1-wire slave protocol with an Arduino to monitor non-temperature related items with our existing software. This is a bit of a hack as the software is designed to read DS18B20 compatible sensors, but I figure it should be possible to submit any data I want as long as the existing hardware/software thinks it's a DS18B20.
