In the early hours of Wednesday, Portland General Electric's computers sent a remote, stealth command to Michael Irving's thermostat in Tigard, Oregon, telling it to turn itself down a few degrees.

Another command came at 4 p.m. – set the temperature up a few degrees. 

Far from being upset at the invisible tampering with his family's air conditioning, Irving was pleased.
