Raspberry Pi SCADA

Lightweight supervisory control and monitoring on a Pi — for sites where a full SCADA system is overkill.

SHORT ANSWER

A Raspberry Pi can run lightweight SCADA: polling PLCs/RTUs, logging historians, alarming, and serving operator dashboards (via tools like Node-RED, Ignition Edge or open stacks). It won't replace a plant-wide DCS, but for a single line, a remote site or a retrofit, a Pi delivers supervisory visibility at a fraction of the cost.

01Where Pi SCADA fits

Single machines, remote pump or telemetry sites, and retrofits where a full SCADA license is disproportionate. The Pi polls, logs, alarms and visualizes — the core supervisory job — without the enterprise price tag.

02Where it doesn't

Plant-wide, safety-instrumented or heavily-redundant SCADA still belongs on purpose-built systems. The Pi is the edge tier: supervisory visibility close to the asset, feeding the bigger picture if one exists.

Common questions

The ones we're asked on every first call.

On industrial hardware with a watchdog, redundant power and store-and-forward buffering, yes — remote telemetry sites are a common and durable Pi use case.
