6．Many people traveled to Las Vegas，Nevada last week for the 50th Consumer Electronics Show，or CES．The 2017show had many examples of"smart home"devices．"Smart home"technology is designed to make life easier for people by letting computers control many things inside our homes．
One such device actually begins working outside the home，when someone arrives and rings the doorbell．You may get informed even when you are halfway around the world that someone come and you can unlock the door for them very easily．
Another use of smart home technology is being able to watch what is taking place in your home wherever you are．Devices can even let homeowners look in on dogs，cats or other pets when they are away．
For heating or cooling，there is a smart thermostat．This device can also send you a message if a big storm causes leaks or flooding．"we're trying to catch it with just a few drops before it becomes a real big problem，"said Mike Sale of iDevices．
While most of the devices can be controlled from anywhere，they also work in the same way when you are at home．Some devices，like Amazon's Echo and Google Home，even let you use voice commands to talk to them．
A concern for many homeowners is the possibility that someone else might find a way to attack these smart home devices．An official from Vivint said his company is sure that only owners of the home can use of information on the devices．Warren Katz from iDevices said his company employs engineers from the defense industry to help prevent hacking．"So they've spent time working on the Patriot Missile and others，and we spend an awful lot of time ensuring that our products are both safe and safe from attack．"
Many of these devices at the Consumer Electronics Show were available before．But now they communicate better nnd can learn to repeat behavior aind habits．All of them can be bought separately，many for less than $100．With such devices，our future homes will become homes thinking for themselves．
