Solar-tracer-Blynk-V3

Compile Arduino Compile Platformio Spell Check

An Arduino project to connect one MPPT Solar Controllers to an ESP8266/ESP32 and monitor it!

You can take a look to the previous version of this software:

What you got with v3:

  1. lots of data from you solar controller (temps, charging/discharging/battery status, stats ... and more)
  2. wide range of customization using a single file (config.h)
  3. automatic time sync between the ESP and the controller on each boot, using NTP time
  4. platformio support
  5. ESP32 support
  6. Configuration over wifi, no needs to compile the code (if you don't want to)
  7. ready for future expansion (more solar charge controllers with different communication protocol/channel)

Feel free to make pull requests if you wish to help improving. There is also a support forum on the Blynk community forums: http://community.blynk.cc/t/epsolar-tracer-2210a-charge-controller-blynk-epic-solar-monitor/10596

You are welcome for suggestions, bugreports, and of course any further improvements of this code.
