• Electricity bill is getting higher and higher (and electricity price will continue to grow).
  
• Maintenance of an air-conditioning device has become an important expenses item.
  
• Guests recklessly leave the meters on which can cause fire when they are out of the apartment or unnecessary electric power consumption.
  
• Losing apartment keys is embarrassing both for the guest and the owner.
  
• Ever-present danger that someone with bad intentions might enter into possession of a copy of apartment keys.
  
• Guests do not turn the air-condition off when in the apartment but keep balcony doors open.
