Data from a Victron can be read out via the VE.Bus.
The VE.Bus is connected to an ESP8266.
The measurement data are transmitted via MQTT.
A big thanks goes to KinDR007 who provided the ESPHome integration.

Thanks for this charing ! it saves my life after a long try without success
Thanks for posting, this is a big help for my camper project!
Hi guys,
short question:
is it really necessary to reduce the voltage from 5V to 3,3V in order to use it with the ESP32?
Did someone already tryed it with 5V?
I use a few liquid-detection sensors they work quite fine with 5V and the ESP32, so I’m just questioning if the additional part is necessary.
Many greetings,
Chris!
Brief question: Can I use the 5V from the VCC to power the Wemos on the 5V-Pin?
Update: My Victron MPPT 100/20 has also 5V, but it works quite fine with the ESP32, no voltage divider necessary!
Do you perhaps have a guide for me on hooking up my 15/75 mppt to esp32? I already flashed the ESP32 but the wiring part I am battling with
So the ESPHome is a substitute for the CerboGX ?
Hi everyone,
I have the problem that I keep getting 0 values back. I’ve already timed the query up and down. However, that doesn’t help. Does anyone have an idea what I can do?
Can you please share your wiring an esphome code for the ESP32 and the 100/20?
I tried on mine a lot but still dont work…
