Can I get the dinner on with my smartphone?
Up to a point. There are a variety of kettles, slow cookers and even chip fryers that can be switched on via Wi-Fi so you can start cooking (or at least heating some oil) when you are still on the train home, but the food must be prepared and loaded before you go, so the time savings are minimal. Take a look at the Smarter Wi-Fi connected coffee maker, which can hold enough ground coffee and water for 12 cups. It starts filling the pot when you press a button on the app, or at preset times (eg, when you get up), or even when you come in through the front door. The price is £180 at store.smarter.am.
