Smart home routine ideas that earn their keep

How a routine works: trigger, condition, action

Every ecosystem builds automations from the same three pieces. A trigger starts it, an optional condition limits it and an action does something. “When the front door opens (trigger), if it is after sunset (condition), turn on the hall light (action).”

Google’s list of supported starters includes day of the week, an exact time, sunrise or sunset with an offset, someone being home or everyone being away, device states such as a door opening, and sensor readings such as a leak or temperature. Apple’s Home app offers the equivalent: an accessory being controlled, a sensor detecting something, a time of day, or people arriving or leaving, and it expects a home hub to be set up.

Which triggers to trust

When in doubt, prefer a sensor or a clock to a phone’s location. See our geofencing guide for tuning presence.

Morning

• Gradual light. A bedroom lamp that rises over ten to twenty minutes before the alarm. See wake-up lighting.
• Weekday and weekend schedules. Make two routines, not one with exceptions.
• Kitchen lights first. Turn on the light you need first, not the whole house.
• Thermostat warm-up. Start heating or cooling shortly before you get up. The Department of Energy says setting back a thermostat 7° to 10°F for eight hours a day can cut heating and cooling costs by up to about 10 percent a year; a schedule makes that automatic.

Leaving and arriving

• Leaving. One button or one phrase (“I’m leaving”) turns off lights and plugs, lowers the thermostat and, if you have a smart lock, locks the door. Do not put anything on it that you would not want to happen if someone triggers it by mistake.
• Arriving. Use a door sensor or a lock event rather than phone location where possible, so a delayed phone does not leave you in the dark. Turn on the hall light only after sunset.
• Guests and kids. Give them a physical option: a switch cover, a button by the door, a keypad. Do not require an app.

Night

• “Good night.” Lights off, doors locked (if you have a smart lock), thermostat to the night setting, a check that exterior doors are closed.
• Motion night lights. Low, warm light in hallways and bathrooms from sunset to sunrise, off after a few minutes without motion.
• Quiet hours. Turn off announcements and chimes on speakers after bedtime.

Alerts worth keeping

These are the notifications that justify the whole system:

• Water leak at the water heater, washer or under the sink. The EPA says the average household’s leaks can waste more than 9,300 gallons of water a year, and a sensor catches the sudden ones.
• Door left open for more than ten minutes, especially garage and back doors.
• Freezer or refrigerator warm. FoodSafety.gov says a refrigerator keeps food safe for about four hours without power if the door stays closed, and a full freezer about 48 hours. An alert helps you act within those windows.
• Smoke and carbon monoxide. Keep these on dedicated alarms. Smart features can add phone notifications, but the alarm must work without Wi-Fi.

Traps that make people turn routines off

• Lights that go off while you are sitting still. Motion-only triggers turn lights off on someone reading. Add a long timer, a presence sensor or use a different trigger.
• Too many notifications. If every door opening pings four phones, people mute the app and miss the leak alert. Alert only on exceptions.
• Routines that fight each other. A schedule turns the lamp on while a sensor turns it off. Keep one owner per device.
• No manual override. If a routine locks the door or turns off the heat, the household must be able to override it with a switch, a button or a voice command.
• Hidden dependencies. A routine that depends on the internet stops during an outage. Prefer local automations for lights and locks.

Start with three

1. Porch or living-room light at sunset.
2. A “Leaving” routine that turns off plugs and lights.
3. A leak alert to every adult’s phone.

Live with them for a week, then add one. If you need hardware for these, the starter kit covers all three.
