I have used the wemo light switch now for some time and love it. I have a few lights in my home which are on three way switches which according to belkin, these switch are in compatable. After doing some reasearch I came accross what seems like might be a work around for it.
This person says through the wemo manager app rules you can make it work
Switch 1 on Switch 2 on
Switch 2 on Switch 1 on
Switch 1 off Switch 2 off
Switch 2 off Switch 1 off
Here is a link to his youtube video
It seems that by using a 2 second of suprression on each rule he avoided the problem in the video.
I was wondering if anyone more informed than I might have any idea if this would actually work.

Yep, I can confirm it works. The supression he mentions is 'cause the WemoManager rules engine is event driven - when the on/off events arrive late they start chasing each other, the suppression option in the WemoManager rule damps this out. For this scenario you need to run WemoManager as a dedicated server (WemoServer).
The physical wiring is a bit tricky - you need to get the line and neutral lines to each box (you can sometimes use ground in place of neutral). If the electrician wired it with 14-3 wiring you can use the travellers to get power where you need it, then wire the load (light) so that either wemo can power the load and both must be off for the load to be off.

Noting it's AutomationManager/WemoManager you need for this as I don't believe the belkin app has this function, Suppression is the attribute 3rd from the bottom of the WhenDevice rule. https://sites.google.com/site/mppsuite/faq/wemomanager/wemorules

This is my video. Just wanted to add that I have four sets of 3 way switches in this configuration and they are rock solid. Mike's app makes it possible, even on a multitasked 2013 Nexus 7. Virtually zero lag when shutting off one light and the server app triggers the other.
