On the ThingSpeak thanks for pointing it out – they have become painful. I have a number of legacy connections I’m setup up for.
Not knowing the architecture of the ODM2/WOF and WaterML 1.1 it was more of a reference.
Thingspeak used to be a lot more open, but Mathwork$ acquired them, and I guess they are making money out of it.
Which is to be expected, but I so appreciate enviroDIY coming along for environmental monitoring (and thanks to the NSF and William Penn Foundation funders)
I am digging into Python libs in parsing the WaterML – but if you have any examples on getting to the data that would be great.
