Scrape Viessmann Heatpump over mygridbox

hello community,

I own a Viessmann heat pump that I have already integrated into the Home Assistant via Vito connect or ViCare. Unfortunately, the power requirement is not displayed via the ViCare app. I have installed an additional grid box from Viessmann, which offers a surface that shows the power consumption of the heat pump. Now I would like to read the website using the scratch function and of course reach my limits. Therefore I need your support.

Which link for the scratch function is relevant.? The page has a login and a subpage with the performance information.

Thanks in advance :clap:
