node-red-contrib-midea-local 0.1.1

Node-RED nodes for local control of Midea smart air conditioners

npm install node-red-contrib-midea-local

node-red-contrib-midea-local

Node-RED nodes for local network control of Midea smart air conditioners. No cloud dependency at runtime — everything talks directly to the device over your LAN.

Based on midea-local.

Install

cd ~/.node-red
npm install node-red-contrib-midea-local

Then restart Node-RED. The nodes will appear in the midea category in the palette.

Nodes

midea device (config)

Configuration node that manages the connection to a single Midea AC device.

• Scan Network — discovers Midea devices on your local network via UDP broadcast
• Authorize — one-time cloud authentication for V3 devices to fetch the device token and key. Your Midea account credentials are used only during this step and are never stored
• Auto-reconnect — connection is automatically re-established with exponential backoff (1s → 60s)

midea in

Reads the current device state when triggered by an input message. Use an inject node upstream to poll at your desired interval.

Output msg.payload:

midea out

Sends commands to the device. Set properties in msg.payload — only specified properties are changed.

Example — turn on and cool to 22°C:

{
  "powerState": true,
  "operationalMode": "cool",
  "targetTemperature": 22
}

Example — just change the fan speed:

{
  "fanSpeed": "low"
}

Accepted properties:

String values are case-insensitive. Numeric enum values are also accepted.
