# node-red-contrib-uk-ea-flood-warnings

[Node-RED](http://nodered.org) wrapper to the UK Environment Agency Real Time
Flood-monitoring [API](http://envrionment/data.gov.uk/flood-monitoring/doc/reference)

## Install
Use the manage palette option to install this node

## Usage
This node allows you to run queries against the UK Environment Agency Flood Warning API

## Configuration
Use the configuration to select the mode.
If floods are selected then `All Flooded Areas` will return
all active flood alerts. If tides are selected then `All Stations` will return details and measurements for all tidal measurement stations.

### Input
 `msg.payload` is not required. The node needs to be configured
to select an area. A list of available areas and tidal stations is
automatically retrieved by the node, making use of the API.

You can override the area setting by setting `msg.floodarea`, which must be a comma separated
string.

### Output
The output is a json array on `msg.payload`. When running in flood mode and there are no
flood alerts in the selected area then the array is empty.
