Quoting:
"It supports home-network based devices, plugging into your router to control them through fixed or Wi-Fi networks, as well as two of the most broadly used wireless home-automation standards, ZigBee and Z-Wave. It means that the Hub can talk to almost every product currently available on the market that doesn’t use an isolated proprietary system."
(...)
"Verdict
The Internet of Things is still a bit of a mess of standards and protocols, with loads of devices unable to talk to each other. The SmartThings Hub is the closest thing I’ve come across to unifying your existing and new kit.
Pros: simple setup, cross-platform, decent app, developer community, multiple standards in one box, unites your existing kit, adaptable
Cons: not compatible with everything, workarounds for non-natively supported devices will be difficult for some, Internet of Things still very early in its lifecycle"
