SmartThings automation guide

Automation (Auto):

based on a logical condition → action structure

Scene:

groups multiple devices so they run together at once

Using both together gives you far more granular control over your smart home environment.

An automation is structured as follows:

IF (condition):

time, sensors, device status, location, and more

THEN (action):

turn power on/off, run a scene, send a notification, and more

AND/OR conditions:

multiple conditions can be combined (e.g., 'after 10 PM AND door opened')

For example, you can build a compound routine such as "after 10 PM + motion detected → lights ON + notification sent."

Time:

set a specific time, or use sunset/sunrise as the trigger

Device status:

plug ON/OFF, door opened/closed, and so on

Location:

detects arrival at and departure from home (geofencing)

Sensors:

a range of sensor conditions including temperature, humidity, motion, and water leaks

Security mode:

automate based on the current mode, such as Home, Away, or Night

• Run multiple device settings at once
• Example: an 'Away' scene → all lights OFF + switch to security mode + sensors armed
• A scene can be set as the THEN action of an automation
• Can also be run from a smartwatch or by voice command

• SmartThings Hub→unified control extending to Zigbee and Z-Wave devices
• Local automation execution→works even without an internet connection
• Faster, more reliable sensor response

※ Most Wi-Fi devices work without a Hub, but a hub plays a major role in advanced automation.

• Break complex automations into scenes first
• Always run a test to check that it behaves as expected
• Give each one a clear name (e.g., 'Living Room Night Lighting Routine')
• Prevent priority conflicts between automations→minimize overlapping time conditions
