I hinted at it but it's important to understand the difference between the brand names and options for the controllers/hubs and the standards for interlinking. They're not 100% separate, but many controllers that originally were only for one platform do support multiple options.

X10/zwave/zigbee/insteon, etc. are related but competing standards.
Smartthings/Vera/Wink/Simplisafe/Iris are "mostly" brand names for the various controller options, though some do also reflect a standard interlinking option too.

LOL welcome to the Internet of Things.
