This is rather nifty. For those who might not make it through the whole medium.com post, I found a live data demo at https://floathub.com/demo
little arduino keeps on ticking. the esp8266 has got to be the most import soc ever made for arduiono. nice to see some community spirit with the github repo. good luck.
Thanks, yes, we're looking forward to more eyeballs seeing the code that runs the device.
