The key is to choose a smart light switch that works natively with your existing smart home hub, rather than one that merely works through Alexa, Google Home, or a separate manufacturer's app.
The best choice depends on your hub and how your home is connected. For example, a switch that pairs directly with a SmartThings hub may not pair directly with a 
Philips Hue Bridge, even if both work with the same voice assistant.
