BME280-Exporter

Golang Prometheus exporter for the Bosch BME280 sensor

Usage

In order to support multiple devices/sensors, the metrics path contains the device and the I2C address of the sensor like the following: /metrics/{device}/{register}.

Since this container runs with a low privilege user, you should change the group of device before mounting it in the container to 500 GID.

sudo chgrp 500 /dev/i2c-1
docker pull spawn2kill/bme280-exporter:1.0.0
docker run -it --device /dev/i2c-1 -p 8080:8080 spawn2kill/bme280-exporter:1.0.0

curl -X GET localhost:8080/metrics/i2c-1/0x76
