Turn a Wemo device on/off using a Wemo switch
What
A flow that turns a Wemo device on/off when another Wemo device is turned on/off.
Why
For some reason, you can't use a Wemo switch to turn another Wemo device on/off, either by using Wemo natively, or by wiring a Wemo input node directly into a Wemo output node in Node-RED.
How
This flow demonstrates the simple fix: The output of the Wemo input node is transformed into a message that a Wemo output node will recognize as an on/off command.
Note
You'll obviously still need to configure the Wemo nodes to correspond to two devices in your network. Personally, I wired an additional Wemo output node to the change node, so that my single Wemo wall switch can control two floor lamps plugged into Wemo socket switches.
