Control your water heater from your gas grill...

One interesting thing about internet of things things is that things can talk to other things.

I just saw an announcement from Wemo and Nest that talks about how you can use your Nest thermostat to control your lights. For example, when Nest detects that no one's home it can signal Wemo to turn off (or on) a light. Conversely, if you're in the Wemo app you can adjust  your thermostat. 


While this is interesting and may be somewhat useful, it brings to mind one of the challenges with the Internet of Things: someone has got to connect these things. And for the time being that someone is you. 

In order to connect these devices to make them work together you need to use apps - one (or more) per device. That's just awful, but perhaps not as bad as having to use a Cisco or AT&T all-in-one-ring-to-rule-them-all type app...

What do you think? Is the marginal usefulness of these connected things worth the hassle of learning, using, maintaining and securing multiple apps?
