I haven't died, just busy with work.
Robert, my driver does not read JSON, it's only simple key-value pairs in a
string. So for example, it doesn't know to strip the quotes off the key or
the value here:
"altimeter": "30.4916869968"
It wants
altimeter: 30.4916869968
I am planning on adopting WYSIWYG (Frederic's) approach of a separate MQTT
topic for each value.
