10 Home Assistant Automations Every Beginner Should Set Up

You’ve installed Home Assistant. The dashboard is up. Your devices are connected. And now you’re staring at the Automations page thinking… where do I even start?

I’ve been there. When I first set up Home Assistant, I spent three hours building an elaborate automation that adjusted every light in my house based on the sun’s position. It broke within a day. Meanwhile, the simple "turn off all lights when nobody’s home" automation I set up in two minutes has worked flawlessly for three years.

Start simple. Here are the 10 automations I recommend to every beginner — each takes under 10 minutes to configure and delivers immediate, noticeable value.

1. Lights Off When Nobody’s Home

This is the single most useful automation you’ll ever create. Use the zone.home person count or phone-based presence detection. When the last person leaves, turn off all lights and non-essential devices. When the first person arrives, turn on the entryway light.

Trigger: state of zone.home changes to 0. Action: call light.turn_off on all light groups.

2. Motion-Activated Bathroom Lights

Put a motion sensor in the bathroom. Lights come on when you walk in, turn off 5 minutes after motion stops. Add a condition: only trigger between 6 AM and 11 PM. After 11 PM, use a separate automation that turns on at 10% brightness so you don’t blind yourself at 2 AM.

3. Morning Routine Sequence

Trigger at your weekday alarm time (or a fixed time). Gradually increase bedroom lights over 10 minutes, set the thermostat to your "awake" temperature, and send a notification with today’s weather. My kids love this one — it’s way more pleasant than yelling "wake up!" from downstairs.

4. Smart Thermostat Schedule Override

If you’re using a smart thermostat, create an automation that overrides the schedule when a window is left open. Use a door/window contact sensor: if a window is open for more than 5 minutes, pause the HVAC and send a notification. This alone can save you $15-30/month on heating and cooling.

5. Bedtime Routine

One button press (or voice command) that: locks all doors, closes the garage, turns off all lights except the bedroom, sets the thermostat to sleep mode, and arms any security sensors. I trigger mine with a bedside NFC tag — tap my phone, everything shuts down.

6. Package Delivery Notification

If you have an outdoor camera that supports object detection (or you’re running Frigate), trigger a notification when a person is detected at your front door during delivery hours (8 AM - 6 PM). Include a camera snapshot in the notification so you can see the package without getting up.

7. Washing Machine Done Alert

Put a smart plug with energy monitoring on your washing machine. When power consumption drops below 5W for 3 minutes, the cycle is done. Send a notification: "Washing machine finished — time to switch the laundry." This has saved us from more musty rewash loads than I can count.

8. Garage Door Auto-Close

If your smart garage door opener has been open for more than 30 minutes, send a notification asking if you want to close it. If there’s no response after 10 minutes, close it automatically. Add a safety condition: only auto-close if no motion is detected in the garage.

9. Low Battery Alerts

Create a single automation that checks all your battery-powered devices daily. If any device drops below 20%, send a notification listing which devices need new batteries. Without this, you’ll only discover dead batteries when something stops working — usually at the worst possible time.

10. Weekly Energy Report

Every Sunday morning, send yourself a summary of the week’s energy consumption by device category. Home Assistant’s built-in energy dashboard collects this data automatically. A weekly notification keeps energy costs visible without requiring you to check a dashboard.

The Order Matters

Set these up in order. Automations 1-3 give you the biggest quality-of-life improvement for the least effort. Automations 4-7 add genuine utility and savings. Automations 8-10 round out a solid foundation.

Once these 10 are running smoothly, you’ll start seeing patterns in your household routines that suggest more advanced automations. That’s when it gets really fun. But the key is to walk before you run — these 10 will keep your home running smarter for months before you need to add anything else.
