there are individual circular buffer data files, timestamp is seconds after Unix epoch. Need a converter for that:

date -r 123439819723 '+%m/%d/%Y:%H:%M:%S'

then 3 axes of B field data

3. data access

mapping of IP to physics locations at

Tool for conversion of JSON to CSV files: dasel on MAC. brew install dasel

$ dasel -r json -w csv < sample.json 
color,id,value
red,1,#f00
green,2,#0f0
blue,3,#00f

Nope, didn't work. Evidently json2tsv works better?
