I'm sorry to hear that the SmartThings app doesn't have the timer function you need for your thermostats. Here are some possible solutions:
Check if the thermostat has its own app - some thermostats have their own dedicated app that provides more functionality than third-party apps like SmartThings.
Contact the thermostat manufacturer - they may have suggestions or updates that can provide the timer function you need.
Use a third-party app - there may be other apps available that can control your thermostat and provide the timer function. You can search for thermostat apps in the app store for your device.
Submit feedback to Samsung - the SmartThings app has a feedback feature where you can suggest new features and improvements. Samsung may consider adding the timer function in future updates based on user feedback.
I hope one of these solutions helps you achieve the functionality you need with your thermostats.
