This is a simple Web surface to control R4875G modules via CAN BUS. It does not do MQTT or Homeassistant. (if you want that please compile your own from the published YAML examples)

Just download the .bin file (r4875g1-can-web.factory 091.bin) and upload it to an ESP32 WROOM32 dev board using this link:
https://web.esphome.io/

Make sure you have the following connected:

tx_pin: GPIO19==tx of the CAN tranceiver board
rx_pin: GPIO21==rx of the CAN tranceiver board

Once the firmware is on the ESP32, it will reboot and after 3 minutes it will
create a hotspot, connect to the hotspot "R4875G1 Fallback Hotspot"
12345678
once connected to the hotspot open your browser and go to
192.168.4.1
enter you wifi credentials, the esp reboots, the hotspot dissapears and stays gone if it can connect to your wifi, now you can find the web interface at:
http://r4875g1-can-web.local/
connect the CAN-H to CAN-H and CAN-L to CAN-L , plug in your R4875G and happy charging :)
