Wassertemperatur.org water temperature (Hamburg Alster)

Just my quick and dirty way of integrating the Data of wassertemperatur.org into Home Assistant, in my case the temperature of the Alster.

I don’t know if it’s accurate, but it is kinda nice to have if you want to go out for water sports

Just paste the following lines into your sensor.yaml:

- platform: scrape
  resource: http://www.wassertemperatur.org/alster/
  select: ".entry-content > h2:nth-child(6) > span:nth-child(1)"
  name: Alstertemperatur
  unit_of_measurement: "°C"
  value_template: '{{ value | replace (" °C", "") | float }}'
  scan_interval: 43200
