I am trying to use the fork by @drogfild https://github.com/drogfild/hass-multiscrape to scrape data from my heat pump (thread https://community.home-assistant.io/t/is-there-any-interest-in-a-stiebel-eltron-climate-platform), but could not get login working. A GET request by curl, browser, or the requests module from python returns the expected content of the login page, but this module gets always a 400 - bad request page. Also tried to add a user-agent to headers, no luck.
Any idea what am I missing?
