Aetria Events is a software-based automation engine for control rooms built around a Node-RED visual workflow designer. It enables low-code, drag-and-drop workflows that react to schedules and real-time signals such as SNMP traps, TCP messages, WebSocket alerts, or API calls. The system can trigger content changes on video walls and operator workstations, send on-screen or email alerts, adjust lighting or HVAC, and drive external devices via standard protocols. It includes custom operator controls and integrated user rights management for secure automation.
