Quick answer
The Device already registered or Someone already connected this device prompt in SmartThings means your Samsung Smart TV is linked to another account or an interrupted setup. Ask the current owner for an invitation, or disconnect the TV from LAN and Wi-Fi first to use Make me the owner.
Safety first
Stop and check this first
- Tapping Register my account or Make me the owner unregisters the previous family member's account from the television; only perform this step with the legitimate owner's permission.
- If you do not disconnect the TV's LAN cable and Wi-Fi connection beforehand, the Make me the owner button will not appear in SmartThings or the app will redirect to network settings.
Safe checks you can perform
- Request an invitation from the current owner or tap Register my account
- Disconnect LAN cable and Wi-Fi on the TV before changing the owner
- Select Make me the owner in SmartThings and forget temporary phone Wi-Fi

Request an invitation from the current owner or tap Register my account
- Who:
- Authorized TV owner and household members using SmartThings.
- How:
- If a family member already uses the TV in SmartThings, ask them to invite you from their administrator account; if your own first-time registration failed due to network instability, retry setup and tap Register my account on the Register and use under my account screen.
- Result that matters:
- Your account receives shared access or finishes registering the television under your authorised Samsung account.
- If the invitation is accepted or Register my account succeeds:
- the TV appears in your SmartThings device list.
- If you need to transfer primary ownership to a different authorised account:

- Evidence to keep:
- Screenshot of the SmartThings prompt and confirmation of which account previously registered the TV.

What it means
On Samsung's official SmartThings support guides for Smart TVs (menu paths may vary across model years and regions), the message Device already registered or Someone already connected this device appears when adding a TV that is already linked to another family member's account, an older account, or an interrupted first-time registration caused by an unstable network. This message reflects SmartThings account ownership state and by itself never proves any hardware component is faulty.

Symptoms and causes
Probable causes · in order
- TV already linked to another family member's or previous SmartThings accountCommon
Another household member or an earlier Samsung account already registered the television in SmartThings, preventing duplicate registration until access is shared or ownership is transferred.
Evidence: Samsung Smart TV is already registered in SmartThings app · SmartThings error: Someone already connected this device
- First-time registration interrupted by an unstable network connectionPossible
If the Wi-Fi or mobile connection dropped during initial onboarding, SmartThings leaves a partial registration record and reports that someone already connected the device on the next attempt.

- Active LAN or Wi-Fi connection on the TV hiding Make me the ownerPossible
When the television remains connected to wired LAN or Wi-Fi during the ownership change flow, SmartThings either hides Make me the owner or redirects to network settings without completing the transfer.
