Nodemcu v1.0 (esp12e) for Victron MPPT
This code was created based on (http://www.svpartyoffive.com/2018/02/28/victron-monitors-technical/) and (https://github.com/physee/Victron.Arduino-ESP8266).
The first link has details for cable construction (tanks travis) and the second was my inspiration. Details from data retrieved from mppt is in victron material (VE.Direct-Protocol-3.25.pdf)
This code able to read all data from mppt and published via mqtt.
I hope that be usefull.
