I'll have to check that app out. I mostly use my alarm system via alarm.com to do most of my lighting, etc schedules (for the devices that are Zwave enabled and use my alarm console as a hub), but I also have that as well as several other skills enabled and linked in Alexa for voice commands.I found the issue to be that every device seemed to want a different app to do the initial setup. They don't all play nice with Alexa. I finally found one app that will discover and control all devices and as a bonus it is tightly integrated with the Alexa device. For those interested it is called Smart Life and is in the Google Play Store. The same thing is available for Apple.
Then I have just a few of the Amazon plugs that are not zwave capable, for stuff like bedroom lamp for voice commands (most of these I don't use schedules, etc for, but I do have just a couple of schedules running via Alexa routines. )
It seems awkward at first, but once you get hooked on voice commands, it feels strange to actually turn on a lamp (especially when you have to walk across a dark room to turn one on).
