I like my Nest thermostat, but I'm more inclined to add smoke detectors from Simplisafe to my security system. They're cheaper, and offer more of an insurance discount because they report to a central monitoring station. I would've liked to see Nest go more towards home automation, or work with window AC manufacturers to integrate Nest controls on their boxes. I'm not too keen on Nest branded smoke detectors.
