Hey everyone! I wanted to share my experience and some tips on setting up a second iPhone on the SmartThings platform. If you’re like me and want to involve your spouse or another family member in controlling your smart home devices, this guide is for you! 
The Situation
I recently decided to get my wife on board with our smart home setup. She’s always been curious about it, and I thought it would be great for her to have her own access. However, setting it up wasn’t as straightforward as I expected. After some research and trial and error, I figured it out! Let me walk you through the process.
Step-by-Step Setup
-
Install the SmartThings App
- First, make sure your spouse downloads and installs the SmartThings app on their iPhone. It’s available for free on the App Store.
-
Sign In or Create an Account
- They’ll need to sign in with their own Google or Apple account. If they don’t have an account yet, they can create one during the setup.
-
Add the Second iPhone to Your SmartThings Hub
- Open the SmartThings app on your iPhone and go to Settings > Family > Add Family Member.
- Enter their email address and send the invitation.
- They’ll receive an email with a link to accept the invitation. Once accepted, their account will be linked to your hub.
-
Assign Roles and Permissions
- Back in your SmartThings app, under Family Settings, you can choose whether to give them full access or limit their control to specific devices. This is great if you want to keep certain devices off-limits!
-
Sync Devices
- Once everything is set up, their app should automatically sync with your smart home devices. They’ll be able to control everything from their phone just like you do!
Tips for a Smooth Experience
- Share Custom Codes: If you’ve set up any custom codes or routines, make sure to share them with your spouse. This way, they can enjoy the full benefits of your smart home setup!
- Test It Out: After setting up, walk through the house together and test out a few devices to make sure everything works smoothly.
- Troubleshooting: If they’re having trouble connecting, ensure both phones are on the same Wi-Fi network and that the SmartThings app is up to date.
Final Thoughts
Setting up a second iPhone on SmartThings is a fantastic way to involve everyone in your smart home journey. It took a bit of time, but now my wife and I can both enjoy the convenience and fun of our connected home!
