node-red-node-wemo
A set of Node-RED nodes for working with Belkin WeMo devices.
These nodes use the uPnP discovery so may not discover your devices if you have a firewall enabled
Install
Run the following command in your Node-RED user directory - typically ~/.node-red
npm install node-red-node-wemo
Output node
The output node switches a socket, a light or group of lights on or off
This should be backward compatible with the pervious version of this node but will benefit from opening the config dialog and selecting the node you want.
The node accepts the following msg.payload
as input
-
A single value
- String :
on
/off
- Integer :
1
/0
- Boolean :
true
/false
- String :
-
A JSON Object as below (lights only and color control is still work in the progress)
{
state: 1,
dim: 255,
color: '255,255,255',
temperature: 25000
}
Note: Currently any invalid value is treated as an off
command.
Input Node
The new input node is now based on uPnP notifications instead of polling. This means messages will only be set when an actual change occurs in on the device. This means the node will not send regular no-change messages.
The output varies depending on the type of device but examples for sockets look like this:
{
"raw": "<e:propertyset xmlns:e=\"urn:schemas-upnp-org:event-1-0\">\n<e:property>\n<BinaryState>1</BinaryState>\n</e:property>\n</e:propertyset>\n\n\r",
"state": "1",

"type": "socket",
"name": "Bedroom Switch",
"id": "221448K1100085"
}
And a lightbulb can look like this:
{
"raw": "<e:propertyset xmlns:e=\"urn:schemas-upnp-org:event-1-0\">\n<e:property>\n<StatusChange><?xml version="1.0" encoding="utf-8"?><StateEvent><DeviceID\navailable="YES">94103EA2B27803ED</DeviceID><CapabilityId>10006</CapabilityId><Value>1</Value></StateEvent>\n</StatusChange>\n</e:property>\n</e:propertyset>\n\n\r",
"id": "94103EA2B27803ED",
"capability": "10006",
"value": "1",

}
