IOTDB Video #3 - controlling 3 things

This video shows three different things being controlled: a SmartThings
Socket, a WeMo Socket, and a Hue light. You can really notice the
interstitial lag on the Hue light.

Note the interface doesn't know anything about what it's controlling except
for what it's been told in the JSON-LD.
