Ember Smart Mug €94
How many things in your life can you make “smart”? Apparently the list is growing and not even the humble coffee cup is safe.
Ember has two functions: hold your drink and keep it warm. It comes with an app, naturally, for setting the temperature and a coaster that also serves as a charging station. So if you forget about your coffee while lost in work (or, more likely, a YouTube loop of fluffy kittens) Ember will maintain its temperature for an hour without the coaster, and all day if you leave the ceramic cup on its charging mat.
It even remembers the settings you used previously, which makes it far more convenient to use. So no matter how long you leave it, there's a cup of stewed, acrid coffee waiting for you. Firebox.com
