Hello all,

sorry if it is wrong place or if the questions are silly, I’m pretty new on this subject.
I have a ESP32 V1 and would like to integrate my Victron Solar Charger 100/20 to be able to read/manage the details from it.
I’ve checked some tutorials and C code samples and I’m not able to read the data with my ESP32.

I haven’t changed anything on Victron firmware or its configuration, I kept it as it is from factory. So I’m not sure if I’m missing some extra configuration.
Theoretically I connected the cables properly (GND→GND and MTTP TX → RX ESP), I tried several GitHub codes, none worked.

Could someone give me some tips or teach me the properly way to integrate my MPPT to my ESP, please?

Any tips about this?
If I need a new sensor or cable or so on?

I’ll move this over to the “Modifications” section, users there will likely have more input for you!

I tried some more GitHub code and couldn’t really make it work on ESP32 V1
Missing SerialSoftware.h and all files I tried I found issues missing random other files

Is there any real working solution integrating MPPT to ESP32?
