Wiring a Wemo Light Switch on a 3-way switch

Jim in Virginia asks: I’m installing a Wemo 3way WiFi Switch replacing an existing 3-way switch.


Wiring a Wemo Light Switch
Electrical Question: How do I wire a Wemo Light Switch?

I’m installing a new Wemo 3-way switch and replacing an existing 3-way switch (model WLS0403). The overall circuit has three (3) switches controlling in all, and works as correctly. One of the existing switches (NOT the one being replaced) is a 4-way; and the other (also NOT being replaced) is a 3-way dimmer switch. The 3-way switch being replaced is a standard 3way switch. The new Wemo has more wires (the one on the load line) powers the Wemo device, but in not sure about the appropriate connections for the others. I can send additional documentation as needed, and work very much any assistance you could offer. Thx

This electrical wiring question came from Jim, a Homeowner in Midlothian, Virginia.

Additional Comments: Very nice, and caught my attention.

3 Essential Electrical Tips

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
