env.io Sense-Client for Raspberry Pi (Docker Container)

This container is pushing temperatures measured on your Raspberry Pi on either env.io or adafruit.io Please make sure that your user has sufficient privileges to read the value of your sensor.

Environment Variables

Please set up environment variables before starting your Docker-Container.
