Invite members using the SmartThings app

The more, the merrier. To let your family or friends use your smart devices, you can invite them to be members of your SmartThings account. Just send out an invitation for a specific location in your account, and if they accept, they'll become official members. Now they can control or manage any of the connected devices in that location.
Note: Inviting members is only available for locations. You cannot add a member directly to a room, only the main location.
Invite via Samsung Account
You can invite members to join certain locations in your account through their Samsung account. Soon, you'll all be able to use the same smart devices.
To invite a member, navigate to and open the SmartThings app.
Tap the Favorites tab, and then tap the Home icon. Select your desired location.
Tap Add (the plus sign), and then tap Member.
Select Send an invitation, and then enter the email used for their Samsung account.
Next, tap Send. Once the user receives the invitation, they can accept it, and then they'll be good to go.

Invite via QR codes
You can also invite members using a QR code.
Navigate to and open the SmartThings app, and then tap the Favorites tab.
Tap the Home icon, and then select your desired location.
Tap Add (the plus sign), and then tap Member.
Select Use a QR code and a barcode will appear. The invitee can then scan the QR code on their phone.
They will need to navigate to SmartThings on their phone, and then tap the Favorites tab.
Next, they will need to tap the Home icon, tap Manage locations, and then tap Add (the plus sign). Then, they can tap Accept QR code invitation.
From there, they can review the on-screen instructions and scan the code to become a member.
Accept the invitation
It's not a party unless everyone is invited. To receive an invitation, the other user must have the SmartThings app installed on their phone and be signed into their Samsung account.
They'll get the invitation as a notification on their phone. All they have to do is tap the notification, and then tap Accept. Once this is complete, they can control the devices added in that specific location.
They can also open SmartThings, and then tap Menu (the three horizontal lines). Tap Messages; a message will appear, informing them of the invitation. They can tap the notice, and then tap Accept to be added as a member.

View or remove members
If someone doesn't use SmartThings anymore, the owner of the location can remove their membership. You can also view members in a location in case you lose track of who has been added.
To view or remove a member, navigate to the location with your desired member. Tap Menu (the three horizontal lines), and then tap Members. Here you can view the location's owner and its current members.
To remove a member, tap More options (the three vertical dots), and then tap Delete. Choose the members you want to delete, and then tap Delete. Tap Remove to confirm. The member will now be removed from that location and won't be able to control any of its devices.

Note: Only the owner of the location can remove members.
