1-wire temperature metrics with prometheus

This is a simple package providing the temperature of a 1-wire sensor such as the DH1820 as prometheus metrics. It reads the w1_slave file at /sys/bus/w1/devices/<sensor>, parses it and provides the read temperature at a webserver running on port 2112 at /metrics.

Usage

Simply run the compiled program and provide the id of the sensor with the -s flag. The id is the name of the folder at /sys/bus/w1/devices/ containing the w1_slave file.
