Case Study: Fuelics improves smart city IoT monitoring with Grafana and Grafana Loki

Monitoring smart city IoT devices with Grafana and Grafana Loki Inside the Fuelics observability stack

Fuelics designs and deploys battery-operated NB-IoT sensors for smart city use cases such as monitoring fuel, water, waste, and parking capacity. As deployments scale to thousands of devices, the team needed a deployment-agnostic way to collect observability data from the edge while tracking device health, network status, and measurement data reliably.

Using Grafana Loki and Grafana dashboards, Fuelics parses sensor logs in the cloud, adjusts timestamps for asynchronous data, and applies low-cardinality filtering for efficient storage and visualization. With Grafana, the team can correlate events across panels, validate calibration and measurement accuracy, and monitor sensor behavior over seven-day windows, helping them confidently deliver simplified, accurate insights to customers.
