I have three WeMo light switches in my home. We call the one in our bedroom Doug. Have been using this switch since January, no issues. We have an Echo in our kitchen and a Dot in the bedroom, both were turning Doug on/off with no issues. Last week when asking to turn on/off both listened but nothing happened. I have reset the light switch, deleted the Wemo app and reinstalled, forgot the device in Alexa app, rediscovered (which it is always seen but still will not turn it on and off). If I go into WeMo app I can turn it on and off. I renamed the light switch to "Bedroom" and now it works. After a few days I tried to change it back to Doug, forgot the device, discovered, Alexa app sees it but again it still will not respond. Any suggestions? I thought perhaps having the echo in the kitchen named Alexa and the Dot in the bedroom named Alexa was maybe causing the issue so I renamed the Echo to Dot. Didn't resolve the issue.
