Technical deep dives, lessons learned, and engineering decisions from the team building HOP Sensors. Raw, honest, and built for engineers.
After evaluating six time-series databases against our requirements — sub-second writes, complex aggregations, and SQL compatibility — here's what we found and why we landed on Timescale.
Read post →Industrial protocols weren't designed with cloud integration in mind. Here's how we built an abstraction layer that handles Modbus, DNP3, IEC 61850, and OPC-UA without custom code for each deployment.
Read post →Grid substations have wildly different baseline behaviors depending on geography, load patterns, and connected infrastructure. We explain why we train individual models and how we manage the cold start problem.
Read post →The path from raw telemetry to ops team notification is longer than you'd think. We trace every hop in our alerting pipeline and show where we shaved latency.
Read post →Electric utilities run critical infrastructure on air-gapped operational technology networks — and for good reason. Here's how we bridge that gap without compromising security posture.
