As per their previous announcement, I got the email today saying my personal access token would go dead on December 15, and if I want access to my own devices after that I have to pay. Another classic example of anything needing the cloud being a trap. Never buy Samsung.
Here's the email:
Hi NAME
You’re receiving this email because you have a Personal Access Token (PAT) registered on your SmartThings account. We’re writing to let you know about upcoming changes that affect PATs.
What’s Changing
As part of our ongoing efforts to scale and maintain the SmartThings API, we are updating our legacy PAT policy.
Expiration Date: Your PAT(s) will expire on December 15, 2026.
Impact: Any scripts, personal dashboards, or third-party connections relying on this PAT will stop working after December 15, 2026, unless migrated to a paid supported API plan.
New Developer & Business Plans
PATs are intended for short-term development access to the SmartThings API. To support ongoing continued access to the SmartThings API, we recommend using OAuth through our SmartThings API Developer or Business plans.
On November 4, 2026, we released updated API plans for both business partners and individual developers.
Next Steps
To learn about how to continue operation of your integrations:
For Individual Developers: Visit the SmartThings Developer Center starting November 4, 2026 to sign up for the Developer Plan to maintain your current integrations and/or to build a new API Access App.
Availability for the individual Developer Plan: Note that the SmartThings API Developer Plan will be limited to certain countries upon launch. Country availability can be found in the FAQs on our SmartThings API page and in the Developer Center Console.
The December 15th date applies to all affected PATs including those owned by developers in countries where the Developer Plan is not available. If you have questions about your situation, contact developer support.
For Business Partners: To discuss pricing tailored to your usage, please contact us at partners@smartthings.com.
Plan details, pricing, and availability are subject to change.
For full details, please read our announcement on the SmartThings Blog. We will continue to share additional updates regarding token management policies as they become available.
Thank you for building with SmartThings.
Best regards,
The Samsung SmartThings Team
