ON THE BOIL

British tech start-up Smarter’s third-generation ‘ikettle 3.0’ allows tea connoisseurs to achieve precise boiling temperatures ( green tea, for instance, should be brewed at slightly below boiling point). Have Amazon’s Alexa voice service? You can ask the kettle to boil itself. Or, use the ‘ Wake Up’ feature and it will turn on when your alarm does. £100 (smarter.am).
