Edge Sensor Sloth: an offline open-weight tool that turns factory sensor data into a morning digest

A developer built a Hacktoberfest entry that tackles the problem of maintenance teams overlooking dashboards, where early signs of equipment failure go unnoticed. The system reads factory sensor data from ESP32 gateways over Modbus and MQTT, and a lightweight local detector flags spikes and slow drift. An open-weight language model, such as gpt-oss-120b, then converts those few summarized numbers into a short two-line digest prioritizing the issues that matter. Because raw plant data never leaves the site and the tool works without internet access, it is designed to keep sensitive production information on-premises. The author notes that the model can be swapped out while the detection pipeline stays the same.
