# Measure Internet Speed with Fast.com

Measure Internet Speed with Fast.com

This project allows you to measure internet speed using the Fast.com CLI and send the results directly to an MQTT broker via a Docker container. You can set environment variables like SLEEP, MQTT\_SERVER, MQTT\_DOWN, and MQTT\_UP to configure the interval between tests and topics for download/upload data. Optional authentication via MQTT\_USER and MQTT\_PASS is also supported.

This setup makes it easy to integrate network speed monitoring with an existing MQTT infrastructure.

You can find the source code and the instructions to run the docker container on [https://github.com/simonjenny/fastcom-mqtt](https://github.com/simonjenny/fastcom-mqtt).
