Latest Readings From Irish River, Lake and Tide Gauges: Water Level, Temperature and Battery by Station (waterlevel.ie)

opwwaterlevelie/latest-readings

The most recent reading of every sensor at the monitoring stations on waterlevel.ie, the Office of Public Works water level service for Ireland, as a GeoJSON FeatureCollection: station reference and name, sensor, UTC time and value. Sensor 0001 is water level in metres, 0002 temperature, 0003 battery voltage, 0011 backup water level. Only stations with reference numbers 1 to 41000, which the Office of Public Works marks as suitable for republication, are returned. Takes no input; the answer is about 700 KB. Contains Irish Public Sector Information under CC BY 4.0, served by Eden Engine; not an official Office of Public Works product.
