It is working on app, but Alexa always says "<device name> is not responding".
I am getting crazy.
I did everything. I cleaned the devices, reinstalled the application, removed the Alexa connection with eWelink and did it all again.
15 minutes is enough to show problems.
Works on App and Alexa says that device is not connected.
Go back to the app to turn the lights. The voice command is not allowed.
