Correct, I didn’t use any level shifter.
If you have a look at the ESPHome documentation for MCP2515 wiring options, there is an approach with only a resistor in the MISO line.
In my case it works perfectly.
Dear Rober,
Thanks you for your great work and for sharing it with us!
This is a great help for me.
For many years I have been using the “can_scan” toolset from Juerg (http://juerg5524.ch) on a Rasperry Pi 2. This is a bit outdated and now I want to replace it with an ESPHome solution as the data already flows into Home Assistant.
I can adopt your examples in large parts. However, my heat pump does not use the same CAN IDs for all values.
Unfortunately, I don’t quite understand how these addresses are calculated. Would you be so kind as to help me here?
I use the following CAN IDs:
180 (boiler) → 0x31
301 (control unit) → ?
480 (WPM2) → ?
500 (heating module) → ?
601 (mixer module) → ?

CAN-ID 180 is not 0x31 !
for CAN-ID 180 you use the number 3 as the first digit and 0 as the fourth digit.
A request to CAN-ID 180 looks like this:
0x31, 0x00, 0xfa, …
Here is the explanation from juerg5524 to the setup of a telegram:
http://juerg5524.ch/data/Telegramm-Aufbau.txt
for ID 301 you use the digits 6 and 1
For a request to ID 301 the package would start like 0x61, 0x01, 0xFA, …
For 480: 0x91, 0x00, 0xFA, …
500: 0xA1, 0x00, 0xFA, …
601: 0xC1, 0x01, 0xFA, …
If you receive an answer from 180 to your own CAN-ID (assuming you use ID 680 at the controller) you get the second digit set to 2 like so:
0xD2, 0x00, 0xFA, …
If you want to change a value at ID 180, you set the second digit to “2”:
0x32, 0x00, 0xfa, …
Thank you for your explanation and the link to the telegram description.
Now I could understand the format.
I already have the ESP32 here and have programmed it accordingly.
I am just waiting for the CAN bus adapter.
By the way, I use 700 (third-party device) as the CAN bus address. Address 680 is reserved for the Comsoft software. But I guess that doesn’t matter as long as the address is unique.
If everything works and there is interest, I can make my adapted version available here. I have a WPL13 heat pump with WPM2 as manager.
Hi,
You can use another address than 680 of course. Just be sure to change the code for the response packages accordingly.
Of course it would be interesting for me and probably others how this works for you.
After a long wait for the delivery of the CAN bus adapter, I was able to put my prototype into operation today:

Now I will install the prototype in an enclosure and definitely put it into operation.

I can’t see the 4k7 resistor between SDA and MISO port in your configuration.
Keep on sharing your progress…
Well, I don’t need the series resistor in the MISO line because I power the CAN bus module directly with 3.3V. Maybe not quite to specification, but works fine.
This is how my finished circuit board looks.
I have inserted a wideband DC-DC converter in the input so that the heat pump also can provides the power. The WPM2 has an output with ~ 22VDC.
In the code I have changed most of the sensors to the state class “total_ingreasing”. This allows them to be used in the Energy Dashboard. “Last Reset” is no longer supported by Home Assistant.
I have also extended the log and debug function with my additional CAN_IDs.
This morning I put everything into operation and it runs perfectly.
Thinking already about implementing some control functions for the heat pump…

May you share how you connected the board to your heat pump?
I also tried to connect via a DC-DC converter in the beginning. But the display of my pump turned dark when I did this.
I additionally have an FEK connected to the heat pump.
What external devices are connected on your pump?
Hi all,
I had finally some time to hook-up the USBtin and it is working like a charm.
The only issue I now have that I can’t seem to find all the can addresses…
Especially the state of the heat pump. Did one of you find the right one?
I tried 0x0112 and 0x176, which should have the flags set based on the state (according to on other thread I follow (code: https://github.com/Hunv/can2mqtt))
Sorry for the late reply, I have a lot of work at the moment…
There are no external devices connected to the heat pump, except for the necessary sensors.
So there is also no remote control (FEK).
The ESP32, with CAN bus and power supply, is connected to port X15 of the WPM2
On this connector is CAN bus (high & low) and a DC voltage of ~ 22V located:
Dear all,
really great job you did here 
if only it would work on my installation 
My Wemos D1 is integrated into HA, wiring between MCP2515 and LWZ304 and Wemos is checked several times.
I used PSTs code as shown above (Thanks!!!), with some adoption of pin layout as required for Wemos D1 and for sure local settings.
In my log file I can only see:
[hh:mm:ss][D][canbus:033]: send extended id=0x680 rtr=FALSE size=7
Any idea?
Thanks for your support!

Jens
@JensPB: If you see nothing at all in your logs, you should probably check your wire-connection.
Below is my updated current code.
As my RAM went out of space at some time after a lot of testing and I ran into boot-loops, I decided to setup new with some changes.
With my new config, you can type a CAN-message as hex-value into home-assistant that is converted via Home-Assistant Script into integer and forwarded via ESP-API to the ESP-device. From there it can
be shown as a package for the CAN-Bus or forwarded to the CAN-Bus by pressing a button.
If you look at the log-files at the same time, you see the answer-packages there, which is good to find new interesting addresses. I added some further sensor-addresses too.
And you can now set the update-interval for each sensor. As I update the value by setting a binary-sensor to true and false using a lambda-call, that is then firing the message.
In Home-Assistant you need to include some input-sensors and a script. The config is below as well.
h_addr is the CAN-Address to send to (usually 3100)
h_idx is the Elster-Index (0000 to ffff)
h_val is the value of the package - if you only want to receive an answer from your device, this is simply 0000.
The ESP-Home configuration is written so, that you don’t have to think about, where to set the ‘fa’ - value. It is set automatically, if needed.
My further idea is, to forward some filtered CAN-packages from the ESP-device directly to home-assistant via API or MQTT. Then RAM is no big problem anymore due to less sensors and buttons in use.

Hi,
Thank you first for your contribution here.
Great work that you do here.
I am new in the Can World, so I need some support.
I receive data from my LWZ304 via my ESP32 with ESPHOME and the MCP2515.
Outside temperature, lead and return. The telegrams are sent from the system every 10 seconds.
But I can´t send a reguest.
e.g. this one
time:
- platform: homeassistant
id: homeassistant_time
on_time:
- seconds: /60
then:
- canbus.send:
data: [ 0x31, 0x00, 0xfa,0x01,0xda,0x00,0x00 ]
can_id: 0x680
- delay: 200ms
There is no answer.
Do I possibly have a problem with the cabling?
I have the ESP32-Wroom-32 model.
It is cabled like this:
Int ----
Sck ---- G18
Si ---- G23
SO ---- G19
CS ---- G15
GND ---- GND
VCC ---- 5V
My config looks like this:
Spi:
ID: McPSpi
CLK_PIN: GPIO18
mosi_pin: gpio23
miso_pin: gpio19
Canbus:
- Platform: MCP2515
ID: My_MCP2515
Spi_id: McPSpi
CS_PIN: GPIO15
can_id: 680
use_exted_id: false
Bit_rate: 20kbps
on_frame:
What do I do wrong?
Many Thanks
Hi,
welcome!
I’m not really sure about the pinnings.
I personally use GPIO17 for the CS-pin - also with an ESP-WROOM-32 device.
Here is another pinout diagram from www.mischianti.org
I just can say, that for sure you should see some traffic in the logs, once you receive any signal from the CAN-bus. There is no need to send requests.
So checking the wires and pinout is not the worst idea.
Sorry, I think I didn’t read correctly.
If you receive a signal but can’t get an answer for a request, you should probably try another receiving CAN-id.
The control unit has not always the CAN-id 180 (addr: 3100) which you use in your code. So maybe you just get no answer, because there is no device with address 180.
I know from another guy, that in his case he sends requests to addr a114.
Have a look at your log-output and post it here. Maybe we can figure out, which device you should address.
Hi robereiter.

Hi,
just identified one of my reasons for not being able to receive correct input (or better none at all)…
So now I at least get some more data, but still not satisfying:
My log looks similar to Miki, but in addition there seems to be no answer on other requests that to ID 180, so it doesn’t work for ID 700:

I hope you are able to interpret this and provide me with an idea
Thanks and have a nice evening!
