Convenience is one of the biggest reasons that people build and purchase smart homes. These homes give users remote access to systems including heating and cooling systems, intercoms, music and multimedia devices throughout the home. Integrated hard drives allow homeowners to watch video or listen to audio in any room; video intercoms make it easy to communicate with others in the home or visitors at the door. Home automation allows an individual to set a schedule for automatic tasks like watering the lawn, removing the need to perform these labor-intensive tasks on a regular basis. The refrigerator is able to download recipes and then display them on its LCD screen and also takes an automatic inventory of items inside, alerting people to what is there, how long it has been there, and when an item is running low! Microwaves can communicate with smart refrigerators and suggest recipes based on what items are in the refrigerator. All of these smart home technologies streamline common tasks.
