Control WeMo Switch With Arduino+Ethernet Shield




Introduction: Control WeMo Switch With Arduino+Ethernet Shield

There are many apps that let you control your Belkin WeMo devices, but there is no a hardware switch panel like the Hue Tap for Philips hue.

So I build one with an Arduino!

Step 1: Materials

For this project you need:

  • An Arduino board. I use the Arduino UNO but you can use any board that is compatible with Ethernet shield.
  • Arduino Ethernet shield. You need the ethernet shield to connect the arduino to the local network.
  • On/Off switch
  • 10k Ohm Resistor
  • Arduino Proto Shield + mini breadboard
  • wires
  • also use a card box as a case for the project

Step 2: Schematic

Step 3: Code

Load the code to the arduino.

On the code you need to set the IP address an the port of your Wemo device (variables wemoIP and wemoPort):

char wemoIP[ ] = ""; //set the IP of your WeMo device

int wemoPort = 49153; //set the port of your device

Grrr -- point your browser to the wemoipaddress:port/setup.xml file for its capabilities.

Nice and simple project! Note that you can eliminate the resistor, connect the other pin on the switch to ground (instead of 5V) and in your code use "pinMode(inPin, INPUT_PULLUP);"

Hi, thank you for your projet. I like it!

As far as i know, there could be a problem adressing the WeMo-Switch, even if you set (in DHCP) a constant IP Address, ports will change (port 49152-49155).
Is there a way to always address the right port?
