Once you get the efamilycloud app put on your iPhone or tablet you need to pair each socket by turning on the light and following the instructions in the app. It takes about 15 seconds to find the device and set it up. Then edit the name to what ever name you want e.g. living room light. Now you need to go to Alexa app and go to skills and find efamilycloud and attach it to Alexa. Now Alexa can control the light or use your iPhone with the app. It took a while for me to figure all this out by trial and error but now that it is working it is fantastic. You can also change the name if you need in Alexa app under smart devices. Don't be fooled by the cheap price it works as good as others costing 6x the price.
