We say “Smart House”, but we mean housing with all modern amenities and household appliances. High-tech gadgets can also be added to this definition. Only a couple of centuries ago, people could not even imagine what the houses would be like today. They did not have electricity, heating, fire alarm, air conditioning, heaters, etc. All they had was candles, sometimes kerosene lamps and firewood to keep the fire and heat in the house. They had to create their clothes from natural resources and only with their own hands. Today we have thousands of factories that specialize in making clothes, household appliances, decor items and other things. Almost every house or apartment has central heating, hot water, electricity, air conditioning, alarm, vacuum cleaner, washing machine, computer.
