There are two ways to create virtual edge drivers, (1) SmartThings-based virtual Switches, or (2) Edge-driver-based virtual switches. You only need to use the custom edge driver if you need a different device type other than a general virtual on/off switch. 

In either setup, the virtual switches will appear in both Google Home or Alexa depending on if you have either set up in your SmartThings account. 

Using the standard virtual switches is far easier than installing and utilizing the custom edge driver.
