Owl additional data required for use in PLEG

I have the current output of my PV panels in a device which the Rfxtrx has created. No other information is being displayed. I know the Rfxtrx receives a lot more data from my OWL, as there is a OWL receiver which receives the data from a wireless transmitter, and then broadcasts it to a website. The data I am interested in the total power generated for the day of my PV panels (marked with a red rectangle). That information is most likely being sent, as its displayed on the website, so I think Rfxtrx is receiving it but not displaying it. Is there is a way to get that information ? It does not necessarily need to be displayed, all I need is the value of the total produced for the day so I can use it in PLEG to trigger a scene when the value is above 10
