Idea of making a project on ESP32 + ETHERNET
Hello, I make various pcb boards and I have a proposal to make a professional board for this project. I wanted to add MQTT broker control over ETHERNET, is it possible to rewrite the software under ETHERNET ?
why not kamil :) everything is possible

Thank you for your reply :) I will make the design of the board and make it available to everyone. The controller will run on 12v DC power and Ethernet , and the outputs will be CAN bus, RS485 and 1-wire (ds18b20)
I made a PCB design and will order a prototype
Input power supply +12V or from USB_C (+5V). Available buses (CANBUS, MODBUS and 1-WIRE).
PCB documentation https://docs.google.com/document/d/1q0n5UrU_Wb4M9KEMclKQVpAS4q2IFIikL5ap5B0-XQ0/edit?usp=sharing
Looks great @kamil2466! I like the idea of making the board based on WT32 - ETH01. I was planning to design some boards for my SSR relays control in similar way. Are you going to publish the project files for the board design?

Yes they will be made available :) For now it is a prototype after launching and testing I will make it available to everyone Go to boneio.eu we do home automation controller
anybody having an idea how the firmware needs to be adapted for Ethernet support?
I would personally go with porting it as a ESPHome component, it would make it more flexible to integrate with different things (including Ethernet). Unfortunately I currently don't have time to do it, also current solution works fine for me.
i'm designing a pcb as well. why would you want to use ethernet instead of wifi?
why would you want to use ethernet instead of wifi?
@vekexasia, my reasons:
- better stability as my WiFiy quality is bad in the cellar
- we care for human radiation exposure. Thus we switch off our WiFi as frequently as possible and it runs on minimum radiation power
- less energy consumption
interesting Vincent. thanks for sharing.
the board i designed (check main repo now) is modular. You can design a hat with Ethernet and disable wifi .... :)

you can also directly use the board from olimex. See https://github.com/vekexasia/comfoair-esp32/pull/51
That should works : https://github.com/nliaudat/esp_canbus 10$/board at jlcpcb
@vekexasia would one of these https://docs.m5stack.com/en/atom/atom_can work out of the box? I think that it should work? Might be an easy solution.
[edit] hmm seems that it cannot power the board from the can bus itself, that's inconvenient then
This one https://docs.m5stack.com/en/unit/Unit-Mini%20CAN should be able to power the board from the can bus.
I have one. I'm trying to use it in combination with an atoms3 lite / atoms3u, but the ESP32S3 doesn't compile. Will get a atom lite (regular esp32) and try with that.

yeah saw that one, but can't order it (yet) in the Netherlands. if you stack that one, you still need to use a grove cable to connect it to the S3 right? Also the (TJA1051T/3) chip does not have isolation compared to CA-IS3050G chip. Don't know if its really needed btw, but sounds a bit safer.
Did you change the board definition to build esphome? the s3 should be supported (s3 is also faster). have a look at an example esphome: https://github.com/fonske/Mitsubishi_procon/blob/main/esphome/boards/board-esp32S3.yaml or https://github.com/esphome/feature-requests/issues/2332
This is the config I'm using:
substitutions:

platform: "ESP32"
rx_pin: "1" # RX = GPIO_NUM_1

and this is the (first) error:

^~~~~~~~~~~~~~~~~~~~~~
Something like this should work:
esp32: board: m5stack-atoms3 variant: esp32s3 framework: type: esp-idf version: 5.1.2 platform_version: 6.5.0
Seems to be ESPHome, it does not support platformIO 6 yet.
In file included from src/esphome/components/comfoair/comfoair.cpp:1: src/esphome/components/comfoair/comfoair.h:2:10: fatal error: esp32_can.h: No such file or directory
It's probably moved or is re-named differently in new version.
[edit] https://github.com/espressif/arduino-esp32/issues/6937 Ah the ESP32 Can lib is old, and does not support new S3 board. Should not be that hard to switch to a newer lib
seems that we need to use an updated lib dep of the esp32_can. I tried to replace it : https://github.com/gekkekoe/comfoair-esp32/commit/c79ed143059842534bc83159b5d50534fab15e61 but it does not seem to work, I'm pretty new with esphome so probably doing something wrong
use (my repo has the adjusted esp32 lib for S3):
external_components:
- source: github://gekkekoe/comfoair-esp32
components: [ comfoair ]
and configure as
esp32:
board: m5stack-atoms3
variant: esp32s3
framework:
type: arduino
version: 2.0.14
platform_version: 6.5.0
this builds :) no need to buy a regular. the S3 is faster
This is my second "build".
Components:
- https://shop.m5stack.com/products/atom-lite-esp32-development-kit
- https://shop.m5stack.com/products/mini-can-unit-tja1051t-3
- 4 +/- 15cm wires (from a UTP cable)
It's small enough to be tucked away under the wiring cover on the top of the unit.
My first build (the original 3D printed box) isn't able to send commands to the ventilation unit. That's why I built the 2nd one, which (turns out) also isn't able to send commands to the ventilation unit. Perhaps it's due to the ComfoConnect LAN C and option box that are also connected to the unit.
@vekexasia I still have a soldered version, but want to replace it. Would like a CAN module that can also power an atom3. Preferably no cable between the atom and CAN module. this https://docs.m5stack.com/en/atom/atom_can would have been ideal.
