Required Capabilities

When submitting your device for WWST Certification, you will select a device category for your device that best fits your device type and functionality. Devices submitted for WWST Certification must contain a minimum set of Capabilities based on device category. The table below lists each device category and the associated required Capabilities. Your device must contain at a minimum all required Capabilities listed for your device category before you submit for WWST Certification.

Your device may contain any capabilities (in addition to the required capabilities) supported by the SmartThings Platform. The capabilities supported by your device will affect the cost of certifying your device. The table below also contains suggested Capabilities for each device category. These recommended Capabilities may enhance your device's user experience depending on your device's features, but are not required.

Before submitting your device for certification, you can obtain a list of all test cases associated with a particular Capability by contacting


The refresh Capability is mandatory for all device categories.

If your device supports firmware updates, we recommend adding the optional firmwareUpdate capability to your device.

Custom Capabilities are not supported by the WWST Certification program at this time.
