Getting Started with DuloNode
DuloNode bridges Alexa and Node-RED, giving you voice control over your automations. You create devices directly inside your Node-RED flows, and Alexa controls them with voice commands. No complex cloud setup, no sharing your Amazon credentials — your devices stay in your Node-RED.
What You Can Control
DuloNode supports 10 device types. Each device appears in your Alexa app and responds to voice commands.
Light
"Alexa, dim the bedroom light to 50%"
Switch
"Alexa, turn on the coffee maker"
Fan
"Alexa, set the fan to medium"
Blind
"Alexa, open the living room blinds"
Garage Door
"Alexa, close the garage door"
Lock
"Alexa, lock the front door"
Thermostat
"Alexa, set the temperature to 72"
TV
"Alexa, turn on the TV"
Plus Speaker and Scene devices. View all voice commands.
How It Works
DuloNode turns your Alexa voice commands into JSON payloads for Node-RED.
You speak
Tell Alexa what you want, like "Alexa, dim the reading lamp to 40%".
DuloNode translates
Your voice command becomes a structured JSON message representing the desired device state.
Node-RED receives
The Hub node delivers the JSON payload to your flow — you decide what happens next.
Example payload
{
"name": "Reading lamp",
"type": "light",
"components": {
"PowerController": { "powerState": "ON" },
"BrightnessController": { "brightness": 40 }
}
}This is a simplified example. See the full payload structure in the voice commands page.
