I have several Sonoff switches in use around my home. Initially they were for Christmas lights but now, I have them on four lights. While I can control them with Alexa, being able to integrate them either with Stringify flows or if either the Wink 2 or Smartthings were to support them, would be awesome. Initially, I purchased switches and bulbs that did not need a hub to control. I quickly learned the error of my ways. Of course, now I have two pages of apps on my iPhone, plus all the actual Z Wave switches and Hue bulbs.
