I was reading the news from CES 2016 and stumbled onto this about the new Samsung TVs:
"Home automation: The company also said it is turning all of its 2016 smart SUHD TVs into home-automation hubs, enabling consumers to control and monitor smart home systems via the TV screen with the inclusion of a free Smart Things Extend USB dongle. More than 200 home devices are compatible with the Smart Things technology.
The company partnered with home-automation supplier Smart Things, which it bought in 2014, to add home-automation technology to the TVs.
Other Samsung smart TVs will integrate with SmartThings home-automation systems, enabling consumers to control certain TV features through the SmartThings’ smartphone app and incorporate the TV into their smart-home routines."
It looks to be a secondary controller USB dongle… I wonder what other uses it may have? SmartThings better polish (fix) up their service, the masses are coming!
