My very knowledgeable HVAC repair guy literally talked me out of getting the Nest thermostat..... something about all one's WiFi data and WiFi activity being uploaded to Google's servers, and not just that which is relevant to the operation of the thermostat.
Don't know if it's true, but it got me thinking, and I'm giving myself the benefit of the doubt.![]()
Exact reason why my nest has not been allowed online, nor upgraded its firmware, since the google take over.
