Environment Agency Flood Gauges

The Environment Agency Flood Gauges integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] offers integration with the UK Environment Agency Flood Monitoring API to provide sensors for nearby water levels. Combined with Home Assistant notifications, you could give yourself a warning if a nearby river was likely to flood your local cycle path or the only road out of your village.

Configuration

Home Assistant offers the flood monitoring integration through Settings > Devices & services > Environment Agency Flood Gauges.

You will be prompted to select a monitoring station. You can find the name of nearby monitoring stations on the Flood information service website. If there are multiple stations with the same name, you can use the ID to filter to the correct one. The ID can be found at the end of the URL from the Flood information service, e.g. for “Westminster” (https://check-for-flooding.service.gov.uk/station/7389), the ID would be 7389.

Sensors for that monitoring station should then appear in your Home Assistant instance.
