Imagine coming home on a hot day and your house has already adjusted the temperature to a comfortable level. Or being able to turn on the lights from your phone while you're still on the way. These are just some of the benefits. One key feature of smart homes is connectivity. All devices are connected to the internet, allowing them to "talk" to each other. For example, when a smart doorbell detects a visitor, it can send a live video to your phone. You can then unlock the door for them remotely if needed. Energy efficiency is another advantage. Smart devices like LED lights and smart thermostats can reduce energy waste. They can turn off automatically when no one is in the room or adjust based on the time of day. This not only saves money but also helps the environment. However, there are risks. Hackers may break into the system and access personal information. Also, relying too much on technology can be a problem if the system breaks down. For example, if the smart lock stops working, you might not be able to enter your own home. Another issue is cost. Installing smart home systems is expensive. While they may save money in the long run, the initial investment can be high for many families. （ ）1. What is a key feature of smart homes? A.
