Sensor now operated by the EPA
I reached out to the OPW to ask about the sensor data, and asked if it could be restored. And they got back to me, saying that the sensor has now been taken over by the EPA, and that I can maybe reach out to them to get access to the data.
This is the EPA page for the Waldron’s Bridge sensor: https://epawebapp.epa.ie/hydronet/#09010
My problem is that they don’t provide an easily readable file of readings for that sensor. On the OPW site, I could download a text file with the latest 24 hours of readings, and pick out the latest reading. But on the EPA site, the smallest data set seems to be 3 months of readings, which is contained within a .zip file, which adds to the complexity of parsing it for the information required.
