Revogi is offering a Smart Power Strip that sort of steps into the middle ground between dumb and smart appliances. Obviously if you want to use it in several rooms of your house you'd have to buy more than one (or choose their individual smart sockets instead), but mainly I'm looking at this for my kitchen or living room. Each plug independently monitors energy consumption in real time, and can be scheduled to count down how long any given appliance is allowed to be in use (their example is gaming systems or televisions). You can also start appliances when you need them (like that coffee maker), or schedule them to stop when they're no longer needed so you never have to worry about whether you've turned something off again.
The neatest thing is the socket roles. You can assign one socket as a master and another as a slave, so the slave appliance only turns on when the master appliance is turned on, all but eliminating phantom power drains. An astronomical amount of energy is wasted in every home by appliances in standby mode, or by charging cables that most of us leave plugged in even when we unplug our devices.
In order to control the Revogi Smart Power Strip, you'll need to download the free app from either the App Store or Google Play (it doesn't appear to work on Windows hpone). Then, you just plug in the strip, attach its Ethernet cable to the router, and you're good to go.
It's not a cheap gadget, but you can pick one up for about $100.00 US. Depending on how much you use its power-saving features, it could pay for itself in no time.
