I tried to install two light switches in the same gang box. One switch (Wemo 1) appeared on my network and the Wemo app. I can use the switch with both my Android phone and Amazon Echo. The other (Wemo 2) will not appear in my Wifi searches. Wemo 1 is labeled 009 and Wemo 2 is labeled A6A. When I first connected the switches and attempted to connect them to my network, both briefly appeared as connections. Ultimately, my network recognized only Wemo 1 (009) as A6A in my network. Wemo 2 (actually A6A) was not recognized. My troubleshooting determined that I had a neutral wire that was not properly attached to Wemo 2 (A6A). I corrected the connection and Wemo 2 works manually, but the network still cannot recognize Wemo 2 and displays Wemo 1 with the incorrect A6A designation. Wemo 2 will display the amber/green for a while after a restart and WiFi reset, but then stays amber.
I have tried resetting WiFi, restarting, turning off the power, resetting my router, telling my Android WiFi setting to forget Wemo 2, moving a range extender within 6 feet of the switches, used a different Android phone, and all the troubleshooting tips I have found in Belkin support and these community forums. All to no avail.
Can you use two Wemo light switches on the same network? Is there any solution?

Hi, @LORENALEP77. You can connect two Wemo Light Switches on the same network, but installing them in the same gang box may cause some problems. Since both devices has its own signal and utilize the same frequency, it may interfere with each other and cause disconnections.
It is recommended that you install the other Light Switch in another gang box.

Absolutely, if the signal is going to interfere it will interfere regardless of proximity to another switch. If, indeed, there is a proximity requirement (one switch to another) Belkin needs to publish that spec. since that would be a critical parameter of function.

Right, it's about as sensible as "use a non-overlapping wifi channel on your router to avoid interference", which is also crap, support trying to pass off blame to the customer's router rather than accept blame for the app or hardare.
If you're having trouble it's likely a problem with app version 1.15.2 as it's broken according to multiple reports. It might be a wiring issue as which wire goes where can be a little confusing in a 2 gang box.
it's rubbish because wemo's broadcast their own signal only during setup, after which all of your wemos broadcast on the ROUTER's wifi channel, and the wifi protocol is DESIGNED to handle interference & overlapping signals and channels. If you have any doubt during setup (as in you can't find a wemo signal to connect to after waiting a few minutes when the wemo starts flashing amber), wire only one switch, set it up, then wire and set up the other (disconnecting the first one during the procedure if you're really concerned).
