In our latest blog post we demonstrate how OPC UA Forge can receive air-quality sensor measurements from Ruuvi devices and stream them through an MQTT broker into a structured information model in Forge. The data is then visualised in real-time or historically via the Forge Grafana Plugin — providing a seamless, no-code path from sensor to dashboard.
Prosys OPC UA Forge 1.5 introduces File and SQL connectivity, enhanced OPC UA Method support, and more flexible data mapping — all shaped by user feedback.
This is a new minor release of Prosys Sentrol. It improves minor details of the OPC UA server implementation.
