Additional additional information:
I’m ALSO able to access the meter using the Mooshimeter-PythonAPI (though the output of ‘Example.py’ is markedly different from what’s shown on the ‘Talk to your Mooshimeter…’ page.) For what it’s worth, I’ve got that working under python 2.7 on a MacBook Pro running OS X version 10.11.2.

And unlike Ryan’s situation, my iPhone app does not heal overnight.
