Smartphones can control your home through voice control, smart locks, smart cameras, and smart plugs. With voice control through apps like Siri, you can lock doors and turn off lights from anywhere. Smart locks allow you to check that doors are locked or unlock them remotely without keys. Smart cameras let you monitor your home in real-time from your phone. Smart plugs enable turning appliances on and off from your phone to save energy. These smart home features are available through home builders like SPM10.
