Ethernet board #19

I have installed the Vroom board and it is performing great. I would love to have it connected to ethernet instead of wifi, but could not find a Vroom board that had ethernet. |

Hi, thanks for the feedback and for your interesting question. I don’t see why this wouldn’t be possible. It wouldn’t work with the current code, but it should work with only minor modifications. This module has the WROVER chip and supports TWAI (CAN bus). As you can see, it doesn’t have a USB port either, so you would need an external programming board and an external 5V power supply. If this is something you’d like to try, I’m happy to help you with this little side project, but I can’t promise it will work in the end. Also, the Wi-Fi section in the YAML would likely need to be removed, so this would be wired Ethernet only. In summary, I haven’t tried it yet, but it should be doable. Regarding GPIOs, my code uses GPIO19 and GPIO21, while the wired Ethernet uses pin 18 and pin 23, so you would need to check if pins 19 and 21 are available (if not, we use other pins to connect the CAN transceiver). Let me know if you feel comfortable editing/compiling the YAML and connecting an external programming board. Also, do you use Home Assistant? ps if this sounds a little involved, there is a potential solution: Install the ESP32-WROOM together with the CAN Tranceiver board in a place with good WIFI and then use a long UTP network cable and use one of the wire pairs for CAN BUS, route the cable to the Huawai, done. |

thank you for your reply! Just for fun, this is how the charger looks like now. |
