Node-RED
Low-code, flow-based programming for wiring together devices, APIs, and services.
Category: Automation & control
What it does
- Build automation logic by connecting nodes on a visual canvas, with no code required for most flows.
- Talks to PLCs, MQTT brokers, databases, REST APIs, and cloud services out of the box.
- Ideal for protocol bridging, data transformation, and event-driven control at the edge.
When to use it
Reach for Node-RED when you need to glue systems together quickly: normalize a sensor feed, trigger an action on a threshold, or bridge a legacy device onto MQTT.
Running on EmberNet
Node-RED can run as more than one instance per node, so you can separate flows by line or function. Its editor opens directly in the dashboard.
