Ordered a bundle of these as Xmas present to self, but kept a couple out of wrapping process for a test run! Easy set up direct from box. Smart Life app easy to link with switch. Integration with Alexa app was simple. Voice control with Alexa didn’t work initially, but this was due to installing smart switch on a different wifi network to Echo device. Re-installing Echo device on the newer home network did the trick! Now have voice control, when at home, and remote control with app when away from home, of my Christmas lights. Just looking for more things to control now!
