Your smart home system can be programmed with different settings that respond to the time of the day, weather, season and your personal habits.
You can have your blinds open and close to block or let in light depending on the time of day, and have that automatically change in the winter months when the days get shorter.
Smart Thermostat will help you save energy by not cooling or heating your house when you are not at home.
Lights will turn on only where needed and when needed. All this without you even thinking about it.
