The WiFi mesh router is a SmartThings hub and a standard router in the same package. Yes all those other things can connect to the internet on the WiFi side as long as you can specify a network to connect to on the device itself. They would connect just like connecting to the router you already have. As a bonus, you have Z-Wave and ZigBee modules on the SmartThings side to automate your home/office/wherever.
