Need a Smart Plug For My System

Hi,

I need to put 2 smart plugs into a single outlet. The only problems are (1) I need smart plugs that are sized so that 2 can fit into a single outlet (or a smart plug that independently controls 2 different appliances). and (2) from my research not all smart plugs work with all systems and I cannot tell from the Alarm.com webapp whether my system is compatible.

How do I figure this out?? Thanks!
