Emil A. Siemes and Stefan Kupstaitis-Dunkler, Solutions Engineers at Grafana Labs, describe a project integrating Garmin devices with Grafana Cloud to analyze fitness metrics such as heart rate. By using Garmin's CONNECT IQ SDK and Grafana Loki, they demonstrate how to collect and visualize data from IoT sensors like sport watches, which sync through smartphones acting as edge devices. This architecture showcases a broader IoT application where simple devices without direct internet access communicate with more powerful edge devices. The process includes setting up a stateless and scalable infrastructure using Google Cloud Run to manage data flow into Grafana Cloud Logs, where users can create dashboards to visualize running metrics. This integration not only serves fitness enthusiasts but also offers a model for IoT systems in various industries.
