The following was posted in the Mobile App today:
Details of termination of 4 services in Labs
We would like to inform the SmartThings users about an upcoming change.
Some existing services in SmartThings will no longer be available as of December 22, 2025.
The 4 services provided in Labs (Turn it off when I leave, Welcome home, No worries while away, and Gentle wake-up) will no longer be supported. Once these services are terminated, their features will no longer be available. However, you can manually create routines for the same scenarios in the Automation tab.
If you have any questions about this, you can send them to us through Contact Us in the SmartThings app.
We sincerely thank you again for using SmartThings.
