Thanks for these hints. I will give it a try when I am back from business travel.
I see two separate scenarios for the two approaches.
-
storing PV electricity. Your solution to force the hot water production definitely makes sense.
-
do not run the heating at night, if the following day is expected to be very sunny or surprisingly high temperature.
For the latter I see a big savings potential for us, so I would be very interested to automate this, or at least have it manually controllable via Home Assistant.
Do you still have the program code to switch between Eco and Comfort or could you give me a tip on how to do that?
Thanks in advance
Hey all,
Thank you all for sharing your achievements!
Iâve successfully connected esp32 with mcp2515 to my WPM4 module and getting some data.

Do you have any suggestions on what to do next ?
Many thanks
Hi Bart,
in the log file I donât see that you send a request.
That would look something like this:
[00:05:09][D][canbus:032]: send extended id=0x680 size=7
So it seems to me that you only see the regular communication between the heat pump and the display.
180 being the heat pump and I have no idea what the 480 is.
What I did to make it work (for me) is the following:
I took something where I know the value and which is displayed on first page of my heat pump display. For me this was AuĂentemperatur.
Then I verified the id of AuĂentemperatur by removing the if check for x0 and x1.
Then I tried sending with different can ids.
For me (LWZ 5S Trend) the 6a2 worked nicely.
Hi Bart,
as RedAnt79 mentioned, your log doesnât look if any request was sent from your component.
If you used my last config from September 21st, make sure that you give it some time, as the values only update every few minutes.
e.g. the sensor âAuĂentemperaturâ has an update_interval of 10 minutes.
If you want them to update more often, you can either reduce the time in update_interval, or you create a script in home assistant as I did it, to force an update by pushing a button.
@Sab3rRid3r
Here is the script I currently use for preparing the warm water. For sure it can be improved.
In the heat-pump Iâve set a time-program, that switches to comfort-temperature during the day, and eco at night. You could also leave it at comfort-temperature over the whole day since I only change the comfort-temperature. But I like it to have some failure mode protection if something goes wrong with home assistant.
I also have a towel-heater in the bathroom, which I only turn on if there is enough power available. Thatâs why I distinguish some values with around 650 Watts difference.

Hey @RedAnt79 and @roberreiter,
Thank you for all your help.
There were couple of issues with my setup.
First of all I have HM Trend (WPM4) it has 2 CAN A and 2 CAN B ports, CAN A ports are used to connect wpm4 to the heat pump mfg etc and the CAN B ports are for ISG, FET and a like. Initially Iâve been connecting to CAN A ports because these were the only ports that returned some data to the ESP but that setup was troublesome since pump was displaying issues about (interrupted or missing communications between components) so definitely a âno goâ there, CAN B ports where not returning any data⌠after a while Iâve found that CAN A ports are running on 20kbps and CAN B are running on 50kbps, so after changing config in ESP home I finally am getting the data from the heat pump.
Second thing was that not all requests where being accepted when can_id was set to 680, mainly Power consumption and Heat generated were missing so I ended up using can_id: 4 for the mcp2515, but the requests that are send are still send with can_id: 680
Third, the power consumption and heat is transported over can_id: 514.
So at the moment I am able to change the pump mode (comfort, eco, etc.), get water target and current, power consumption, heat generated, circulating heat in the underfloor heating, so, so far so good.
There are still things missing like the FES not answering the temperature or humidity so I guess I have to find correct can_id, or eco and comfort tank target settings
I am trying to get the missing values to show up although Iâve got most of the values that I really cared about.
Now what I need to figure out is how to change comfort and eco heating temperature, it would be great to be able to set that and connect to my Heatmiser unit and set the temperature from there⌠
Thank you for all your help and great work!

Hey Guys, can anyone please post their pinouts for either the Esp32-wroom and/or Wemos d1 mini?
I have both but I cannot confirm the MCP2515 device works.
Initially I had a raspberry pi zero with a CAN hat, that device works and I see data coming in, using it as a esphome alternative is not possible so I got a MCP2515 but whatever I do nothing is coming in from the Stiebel. When I link the MCP2515 with the RPI also nothing is showing, neither using the D1 nor esp32âŚ
I suspect the issue is with the way the MCP2515 is connected to the esp/d1 but I wanted to be sure before I order a new oneâŚ

As to âwhy donât you use the rpiâ?
I cannot get the can_tools to compile, I have been playing with python to receive the messages which works but all the stuff thatâs needed to convert the CAN message to something usable is not something I can do without first properly learning pythonâŚ
The esphome route is much easier and is exactly what Iâm looking forâŚ
Hey @Radiotechniman
I have it setup as follows
VCC â V5
GND â GND
SCK â G18 (GPIO18)
SI â G23 (GPIO23)
SO â G19 (GPIO19)
CS â G17 (GPIO17)
Can id â 4
Bit rate â 50kbps
Well that helped a bit, Iâm now seeing some response, just not the stuff Iâm looking for
Could this be the IDis not correct?

Just a quick question,
is it possible to use CAN with Home Assistant on a Raspberry PI with this CAN HAT?
Properties:
Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+
CAN function, onboard CAN controller MCP2515 via SPI interface, with transceiver SN65HVD230
RS485 function, controlled via UART, half-duplex communication, with transceiver SP3485
Reserved control pins, allows to work with other control boards
Comes with development resources and manual (examples in wiringPi/python)
Specifications
Operating voltage: 3.3V
CAN controller: MCP2515
CAN transceiver: SN65HVD230
485 transceiver: SP3485
Dimension: 65mm x 30mm
Mounting hole size: 3.0mmHello, since the outside temperatures go into the negative I get strange values. Looks like 16bit 65536 overflow to me. Do you have any idea how to fix this?

Usually you get this kind of answer if you query the wrong idx. E.g. the wrong device where this index is not available. Probably you should try to ask one of the other can addresses in the bus.
The index should be correct I think because when the temperature is positive everything is working like expected. Plz take a look at the pictures. Thanks in advance.

Brainstormin, possible solution?
When value > e.g. 65000
256 * 256 = 65536
65536 - value from reading in this case 65526 = 10
10 / 10 *-1 = -0.1 degree celsius
I have the same problem with my LWZ 304 Flex
I must admit, now that youâre telling this, I think I had this problem somewhere in the beginning of the year. But temperatures never went below zero since then. Is there a standard way to convert into float with negative sign?
Otherwise I think the solution proposed could work.
I have the same one, it receives the data from the CANbus perfectly but converting that to usable data is where I stopped. As mentioned I tried with the normal tools as with python but ultimately went with a Wemos D1 + Can which works pretty well
