If you watch the unhappy early adopter YouTube videos of Nest thermostats, this outcome is pretty predictable. There&#x27;s a level of quality control you need to put up a web app, which won&#x27;t physically affect anyone if it happens to crash for awhile. Then there&#x27;s a much higher level required when you&#x27;re controlling things in the real world.<p>This outcome was predictable from the experience of those early adopters.<p>EDIT: Why couldn&#x27;t Nest fall back to being a dumb thermostat? Lots of smart device makers should consider having such a fallback.
