Help creating a SCRAPE sensor

I’m trying to use SCRAPE to create sensors from my FV inverter (that is not recognized by HA, but has a web interface with its running data).
It’s two hours I’m unsuccessfully trying to understand how to extract the data I need… :frowning:

I.e., the current page is this one; if I would to retrieve the “PV Production Power” value (currently 90 W), what “select” should I specify during the entity creation?!
