It's very MIT. It's also an illustration of what went wrong with the "internet of things" concept. Sensors are easy today. Actuators are hard. Most "IoT" things can't do much. Try to buy a home power window. They exist. They're an exotic luxury home item. Even controllable home HVAC dampers are rare. It makes good sense to have a system where windows, fans, dampers, heaters, and compressors are all coordinated to max…
I've got two in my house! Of course they weren't wired to anything, and one of them had its wires hidden behind drywall (and the accessible one seems to be broken, but I'd have to disassemble the ductwork to figure out why). Thankfully, the functional one is actually pretty useful, and I was able to hack it up so call for cold/heat closes off the basement, preventing the basement from turning into a freezer. Of course, if Nest would give us an API (again), I could also modulate the cooling if the basement gets too cold.
