Question about Hombli Smart Swiss Socket

Hello, I use the Smart Socket to measure the output of the small plug-in solar system. Since it doesn't have that much power, but the socket or the Hombli app only shows the power in kWh, this is relatively inaccurate (with Shelly I can see the current power and can calculate totals over periods of time). Can I somehow set this to wh instead of kWh? Many thanks for the info
