Overview

This documentation is for developers who connect devices to Fundamentum and build on top of it. Start with the quickstart to get a device online in about 15 minutes, or go straight to the guides and reference.

Fundamentum is an IoT platform for connecting, securing, operating and analyzing fleets of devices. Devices provision themselves and connect over MQTTS through the Devices API and the MQTT broker. You manage your fleet from the Hub, control access with Connect, route data with topics, connectors and cloud functions, and query it with Insight. You can automate the same work through the Public API and the fun CLI.
