From substations to solar farms, Sentrel unifies voltage, current, temperature, frequency and status from legacy RTUs and modern inverters alike — without ripping out the gear you already run.
Your assets are spread across hundreds of square miles — distribution substations, pad-mount transformers, switchyards, peaker generators, and growing fleets of solar inverters and battery storage. Many run on RTUs and IEDs installed decades ago, speaking Modbus or DNP3 dialects that never agreed to talk to each other. Visibility is fragmented across SCADA silos, vendor portals, and spreadsheets, while regulators expect provable, tamper-evident records you can produce on demand. A single overheating transformer or a frequency excursion that goes unseen for minutes can cascade into an outage, a violation, or a six-figure asset loss.
Point Sentrel at the equipment you already operate and start watching the readings that actually predict failure. The lightweight Node-RED edge connector pulls from legacy and mixed-vendor devices over Modbus and OPC-UA on a gateway you likely already have on site, then forwards over MQTT or HTTPS — no proprietary sensors, no manufacturer cooperation, no rip-and-replace.
Describe an asset and its thresholds in plain English — "alert if transformer oil temp exceeds 85C or feeder frequency drifts past 0.5 Hz" — and Sentrel's LLM generates the typed schema and rule set in minutes, not a 6-18 month integration. Every reading is validated, run through a per-reading rule engine, and stamped with a tamper-evident integrity hash plus a full WORM audit trail built for 21 CFR Part 11-grade scrutiny. When something crosses a limit, your team knows instantly over WebSocket, in-app toast, webhook, or email, with RBAC and scoped API/MQTT keys keeping each crew to its own assets. The outcome: distributed sites you can actually see, faults caught before they cascade, and compliance evidence that's there when the auditor asks.
It works with what you own. A lightweight Node-RED edge connector reads legacy and mixed-vendor PLCs, RTUs and sensors over Modbus and OPC-UA on a gateway you likely already have on site — Raspberry Pi, Teltonika, Advantech or Siemens — and forwards over MQTT or HTTPS. No proprietary sensors, no manufacturer cooperation, no rip-and-replace.
Minutes, not months. Describe the equipment and your thresholds in a sentence and Sentrel's LLM generates the typed data schema and alert rules for you, instead of the typical 6-18 month SCADA integration project.
Yes. Every reading carries a tamper-evident integrity hash and lands in a full WORM audit trail built to 21 CFR Part 11 standards, with RBAC and scoped API/MQTT keys controlling who sees and changes what — so you have provable, defensible records when an auditor or regulator asks.
Describe what you want to watch, connect the gateway you already own, and be live this afternoon — no integrator, no proprietary hardware, no six-month project.
