Imagine telling Siri to dim the lights, lock up, or start off your Movie Night scene. Sounds good, right? This guide will show you how to get Siri working with Samsung SmartThings. We will cover what you need and fix any problems that might run into you.  
It’s super simple for you, we promise! 

Introduction: Why Connect Siri with SmartThings 

Before, if you had both an iPhone and Samsung SmartThings, using them together was a pain. You need different apps: HomeKit for Apple and SmartThings for your connected home setup. 
But now, SmartThings works with Siri Shortcuts, so those problems are gone. Now you can make things happen in SmartThings just by talking to Siri on your iPhone or Apple Watch. 
What this gets you: 

• iPhone users can tell SmartThings what to do without lifting a finger. 
• Apple Watch users can control everything right from the wrist. 
• Families with both iPhones and Galaxy devices can finally get along. 

Basically, linking Siri and SmartThings makes everything easier. You get the smart features of Apple’s voice control and the flexibility of Samsung’s gadgets all in one. 
What You Will Need 

Here’s what you should have for setting up SmartThings with Siri: 

Necessities	Specificities
SmartThings App	Newest Version (v3.4.2 or higher) from the App Store.
iPhone or iPad	It needs to be running iOS
SmartThings Account	Make sure it’s all aligned with your Samsung details.
Peaceful Devices	Like lights, plugs, thermostats, locks, etc.
Good Internet Connection	Your iPhone and SmartThings Hub need to be on the same Wi-Fi.
Apple Watch (Optional)	If you want to control things from your wrist, make sure it’s on watchOS or later.

 
Got all that? Great! You’re ready to link Siri to Samsung SmartThings and start bossing your smart home around with your voice. 
Step 1: Update SmartThings App on iPhone 

First, you need to update your SmartThings app on your iPhone. 

• Go to the App Store. 
• Look up SmartThings. 
• If there’s an Update button, tap it. 

Make sure you’re on version 3.4.2. Or later. That version has the Siri Shortcuts thing, which came out in the November 2025 update. 
After you update, open the app and sign in to your Samsung account. If you already use SmartThings for your lights or other devices, you’re already partly done. 

Step 2: Enable Siri Shortcuts for SmartThings routine 

Secondly, let’s get Siri Shortcuts working with your SmartThings device as this is what lets your boss your Samsung smart home using your voice. 

• Open the SmartThings app on your iPhone. 
• Hit the Routines tab. 
• Pick a routine you want Siri to handle and say, Goodnight or Movie night. 
• Tap Add to Siri. 
• Say a phrase that comes to you. Say something like, Hey Siri, I’m back from work. 

After you do that, Siri will know what you mean and start off your SmartThings routine right away. 
Additional Tip: Keep your phrases short and sweet. Siri works best when it can nail commands like Movie Time or Lights Out. 

Step 3: Create or Import SmartThings Routines 

If you’re just getting started with SmartThings, here’s how to make some recent automation before you link it up with Siri. 

• Open SmartThings, go to Routines, and tap +Add Routine. 
• Pick what starts the routine like a time, when it senses movement, or when you turn it on yourself. 

• Then add what you want to do: 

1. Turn the lights on or off. 

2. Change the thermostat. 

3. Lock or unlock doors. 

4. Turn on the TV or speakers. 

For example, you can make a morning routine that flips on the lights, gets the coffee going, and warms up the house, all with one Siri command. 
If you’ve already got routines set up, you can just pull them into your Siri Shortcuts. 

Step 4: Add Siri Trigger Phrases 

Now we have come to the fun part that is teaching Siri what to do. 

• Go to your routine section in the SmartThings app. 
• Tap Add to Siri again (if you have not already). 
• Record the phrase you want to use. 

Here are few ideas: 

1. Hey Siri, Goodnight: This turns off the lights and locks the doors. 

2. Hey Siri, Gaming Time: This turns on your LED lights and lowers the blinds. 

3. Hey Siri, Start Work: This turns on your monitor and sets the temperature. 

You can even use more than one phrase for the same thing. That’s useful if people in your family want to use different commands. 

Step 5: Test and Fix Problems 

After you set up your commands, give your Siri SmartThings setup a try. Just say your command out loud like, ‘Hey Siri, movie night.’ See how fast SmartThings react. 
If it doesn’t work, check these things: 

• Make sure the routine is actually in Siri. 
• Confirm that both devices are on the same Wi-Fi network. 
• Be sure Siri can access SmartThings (go to Settings> Siri & Search> SmartThings> Allow Siri) 

If Siri still isn’t responding, delete the routine shortcut and add it back. Sometimes, re-syncing the SmartThings app after an update fixes small issues. 

Bonus: Control SmartThings from Your Apple Watch 

The best thing about using SmartThings with Siri is that you can handle your whole house right from your wrist. 
Here’s How It Works: 

• Make sure your Apple Watch has watchOS 10 or later. 
• Put the SmartThings app on your watch or open it if it’s already there. 
• See your list of routines. 
• Tap a routine or just ask Siri on your watch to start it. 

For example: Say you’re leaving and don’t lock up. Just tell Siri, goodnight on your watch, and your SmartThings lock will lock right away. 
This makes using your smart home way easier, mostly when you don’t have your phone handy.
