2 Smart home devices
2.3 Smart (kitchen) appliances

As was already said earlier, the smart home is a home that contains smart appliances, i.e. appliances which are equipped by wireless interface and which can be remotely controlled [11]. Wireless interface can be realized by Wi-Fi, Bluetooth or NFC technologies. Smart appliance remote controlling is performed by a smart phone or tablet application that also provides information about appliance status. At the same time smart appliances can warn users of various operation events. Applications for smart appliance control are most often available for Android OS and iOS. Applications are often developed by each smart appliance producer or the producer builds its own ecosystem with one application able to control a set of producers’ smart appliances. Certain group of electronics producers is developing Home Connect platform which enables users to communicate with smart appliances of different producers. Currently, this platform is supported by appliances of Bosch and Siemens. Other partners are e.g. Amazon Alexa, Nest or IFTTT [12].

If an ordinary home appliance could become smart except for a wireless interface it needs a set of sensors which define functions and abilities, what can be done with that appliance. At present time there exist following smart appliances and functions they support:

- smart fridges - temperature set up, control of other functions, remote view to the fridge via integrated panoramic camera. LG introduced a fridge with virtual intelligent personal assistant Alexa developed by Amazon who the users can talk to and except for standard commands they can tell her, what foodstuffs and when she should order. The fridge is equipped by a 29” touchscreen depicting content of the fridge and foodstuffs with close expiration date. It is connected to social networks and it can warn a user of friend birthday [13].
- smart ovens - information about appliance status and baking process, temperature or programme change.
- smart dishwashers - dishwasher activation, suitable programme recommendation, washing process monitoring, information about number of tablets in a dispenser.
- smart washing machines (dryers) - programme, water temperature and spin speed set up, washing process monitoring.
- smart coffee makers - coffee brewing, selection of a programme.
- smart vacuum cleaners - activation of cleaning, notification of completion, taking control (it is possible to play with a vacuum cleaner like with remote control cars).

It is clear that smart appliance assortment will extend. We can await smart toasters, cookers, kettles, forks, pans, weighting machines, grill machines, etc. Griffin company even offers a futuristic mirror that can show you e.g. weather forecast, world news or oncoming events during morning make-up or teeth cleaning.
