There are a number of different home automation options available including remote operation and total automation. Recent technological advancements in home automation systems has brought the price down in recent years.
Remote appliance control
You don't necessarily have to rewire your entire home to indulge in a little automation. Many people link their appliances together with fairly simple wireless components. One popular example is the automated stove. With an automated stove, you can program it to start preheating at a certain time of day so it's ready for use when you get home from work. Another popular option is remote control lighting, which allows homeowners to control household lighting from anywhere and boost home security.
This can refer to either the total automation of a room or the total automation of your whole house. Of course, total automation of an entire house can be extremely costly. This means that most people only automate a specific room or set of rooms. The extent to which you can automate a room will depend entirely on your budget.
For example, there are extremely advanced systems that utilize voice-recognition software. The analysis is then gauged against a preset list of stored voices so the system can tell who is in the room. The system then uses this information to adjust the room's heat and light settings to match the presets of user. There are also home automation systems that allow you to control these settings with dedicated voice commands. This gives you more control over the system and provides additional customization options.
