Hello @HeMan,
Which parameters are you not visualizing? Could you share with me some screen captures of the logs and device UI, please?
I was able to see the values of Energy, Power and Voltage as you mentioned, and when I send the events to change these capabilities value, the change is reflected in the SmartThings App (see the picture below).
To visualize the custom attributes and buttons for the commands such as kVAh, reactive, real, lastUpdate and reset in the mobile app, you should create custom capabilities, for more information about this, see the post of the Custom Capability and CLI Developer Preview .
