An internet connected software controlled thermostat? Who could imagine such a device would be open to this mode of failure? Who couldnhave predicted this disaster?
Oh hang on. I did, didn't I.
No doubt someone will explain how being able to turn the thermostat up or down using their smartphone is worth what just happened, and what will undoubtedly happen again and again, given that the firm in question didn't anticipate a failure showing up at the worst possible moment.
