w1retap - Data logger for 1-Wire weather sensors

w1retap [OPTIONS]

The w1retap package reads weather sensors on a 1-Wire bus and data logs the retrieved data to the configured databases or files. It supports a number of different 1-Wire host bus adapters and 1-Wire sensors designed by Dallas Semiconductor Corp (now Maxim Integrated) and compatible sensors including those from AAG Electrónica and other hobby sensors.
