Alexa Node-RED integration with DuloNode

This flow begins with a DuloNode Hub and a DuloNode Device node. The Hub listens for voice commands from Alexa, while the Device represents the smart device you want to control—such as a light, fan, or switch.

When you speak a command to Alexa, the DuloNode Hub picks it up and passes it to the appropriate DuloNode Device. From there, you can look at the payload to figure out what action needs to happen—for example, turning something on or off.

The last step is to send that action to your actual hardware. This usually means sending an MQTT message or an HTTP request. The format, topic, or API URL you need will depend on your specific device, so check its documentation for the correct details.

Getting Started with DuloNode

To get started with Alexa Node-RED integration using DuloNode, you'll need two key nodes:

DuloNode Hub – This node connects your Alexa environment to Node-RED.
DuloNode Device – This node represents the smart device you want to control, like a light, fan, or switch.

Once these nodes are set up, you can start building flows that respond to Alexa voice commands and control your hardware through MQTT, HTTP, or other supported protocols.

Note: some third-party nodes may appear with blank styling, and not as they appear in the Node-RED Editor.
