Hi @g1za,
Thank you for your follow-up. To provide further context on the instantaneous power feature, I recommend checking this SmartThings Community post for more details about how capabilities work across devices and the API.
In summary, while the SmartThings app uses the OCF (COAP) protocol to display certain values, including those written directly by the device (such as power or temperature readings), the APIs don’t use OCF and instead rely on the profile that defines the available values.
This could explain why some features, like instantaneous power, might not be available in the API even though other energy consumption data is reported by your device. I recommend checking with the manufacturer for more specific details on whether real-time power monitoring is supported for your model.
Let me know if you have any further questions!
