Sengled Smart Plug - reported kWh

Hi There,

I’m trying to report used energy with some Sengled SmartPlug (model E1C-NB7).

I’ve noticed the reported power would be more or less 10x the used power.
I’m using a stand alone energy tracker, running a device that is using 85w for 1h30, would be 0.1275.
The Sengled plug reports 1.15 KWh.

Am I the only one noticed this ?

Is there a way to correct this with HA ? with a template ?

Thanks !
