The reason why the smart home is such a failure is because even the "smarter" home is a total failure. I had a programmable thermostat in my residence. I always used it in "hold" mode and just turned it off when I left for the day. This thermostat also had the option for the power company to disable the AC during peak load. I could care less about this as the interruption was brief. The problem was after they re-enabled the AC, the thermostat always returned to "program" mode. Twice this turned on the heat with a setting of 85 F in the middle of the summer. Needless to say, that thermostat is now sitting in a cupboard.
