### 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:
* *v1* [Tracer-RS485-Modbus-Blynk](https://github.com/jaminNZx/Tracer-RS485-Modbus-Blynk)
* *v2* [Tracer-RS485-Modbus-Blynk-V2](https://github.com/tekk/Tracer-RS485-Modbus-Blynk-V2)

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.
