About

Länderübergreifendes Hochwasser Portal is an integration that reads river gauge data for Home Assistant. Since the original portal closed its open API in July 2023, it queries the 16 state portals instead, and some of those are read by web scraping. Each gauge, chosen by its ID during setup in the UI, provides sensors for water level in centimetres, warning stage from 0 to 4, and flow rate in cubic metres per second. Not every gauge reports all three values, so entities for unavailable values are skipped by default, and a setup option adds them anyway. Some gauges appear on more than one state portal, and one of them can be selected. The integration depends on the vendor's cloud and is installed through the Marketplace.

From the README

This Home Assistant integration started as integration for the Länderübergreifendes Hochwasser Portal (LHP), but due to the fact that the LHP locked their formerly open API in July 2023 this integration was rewritten to query the 16 state portals to get all information. The positive side effect, now more pegel are available, because the different state portals didn't report all their pegel to the LHP. The negativ side effect, some of the state portals need to be queried by web scraping and therefore need to be adjusted if the portal's design changes.
