Swiss Hydrological Data

The swiss_hydrological_data sensor will show you details (temperature, level, and discharge) of rivers and lakes in Switzerland.


The station overview contains a list of all available measuring points and will help to determine the ID of station which is needed for the configuration.


To enable this sensor, add the following lines to your configuration.yaml file:

# Example configuration.yaml entry
  - platform: swiss_hydrological_data
    station: STATION_ID
      - temperature
      - level
      - discharge

Configuration Variables

station string Required

The ID of the measurement point.

monitored_conditions list (Optional, default: temperature)

The list of measurements you want to use. Available is temperature, level or discharge.

Sensors are exposing additional values through their attributes for all available conditions:

  • max-24h: The maximum measurement for the last 24 hours.
  • mean-24h: The mean measurement for the last 24 hours.
  • min-24h: The minimum measurement for the last 24 hours.
  • station_update: There is a time span between the sensor update in Home Assistant and the updates from the stations. Include those information if you are building automations based on the discharge of a water body.
The sensors don't show the latest measurement, but those from the last hour due to the source of data. Some stations also don't provide data for certain measurements.

The hydrological measurements are coming from the Swiss Federal Office for the Environment (Bundesamt für Umwelt - Abt. Hydrologie) and are updated every 10 minutes.
