Does the Wyze Plug work with the Smart Life app?
In what way? It is not a SmartLife device so I would not think so?
It is currently not integrated with the SmartLife app, you can use the sensors through IFTTT to trigger SmartLife items.
If I use the Smart Life app, IFTTT, and this NEO Wireless Wifi Siren Alarm (https://www.ebay.com/itm/202821330438), will I be able to control the siren alarm (turn it on and off, trigger it) using IFTTT and Wyze sensors or Alexa and Google Home?
