Nest's PR response seems like it's hurting the brand reputation beyond the damage caused by the failure itself. Software is hard, software & hardware in a closed system is harder, software & hardware with physical sensors and variable, external analog interfaces is even more difficult. The Nest responses seem like they could be "technically" true. However, Nest's overall failure seems to be the lack of robust enough self-diagnostics to identify bad installs, as well as having weak fail-over behavior. It almost sounds like Nest needs a backup "dumb" thermostat built into the hardware in the event that the sophisticated portion of the Nest hardware is shutdown for any reason.
