Accessing Power Consumption data from Wi-Fi Kit MIM-H04EN

I have a Wi-Fi Kit MIM-H04EN for our Air Source Heat Pump. I can access power consumption data in the SmartThings app under the Energy Monitor option. However if, as has happens sometimes, there is a mains power failure i.e. the Wi-Fi Kit loses power, even for a short period of time, the History data is lost. It would therefore be useful if the power consumption data could be accessed by an API etc and recorded remotely. However it does not appear that there is an API available to access this data. The developer of ConstantGraph suggests that Samsung are not making this data available to developers. Can anyone suggest a solution please?
