Our furnace/air conditioning system is scheduled for replacement this coming Monday which made me pay a bit of extra attention to the following item at Slashdot.org. The cooling coil of the current air conditioning (heat pump) system had been leaking since about year six of its 14.5 years of use, but only now enough that the location of the leak was easily detected, and the new system is touted to be much more efficient - by 15-20 percentage points. It was not for the reason mentioned in the posting that I asked Hunky Husband to check into having the "internet control" feature of the new thermostat disabled. I don't want any of my appliances to be connected to the Internet.
When the Apocalypse comes, I don't want "them" controlling my home. (It's bad enough that "they" will be controlling our on-purpose computing systems and our cars!) As it turns out there are two versions of the new thermostat - one of which is NOT connected to the Internet. That is the one that HH ordered.
Neither Nest nor Google has stated any intention to turn Nest's hardware into more than it is right now. Protect is an alarm, the Thermostat is a thermostat. But as Google ramps up its vision to connect every aspect of our world, from Android Wear to its acquisition of a company that specializes in high-res, near-instantaneous satellite imagery of Earth, it's easier than ever to see why it would cough up billions for a company that has installed hundreds of thousands of Wi-Fi connected devices in the homes of Google users."
