Experience Combi 4E, CRC-Errors #20

Open gmanic opened 1 year ago

gmanic commented 1 year ago

First of all - thanks for this wonderful ESP implementation to get the Truma "under control". My setup is a Combi 4E (C4.01.02 / 50.00, H1.01.00 / 340.0A) together with a dedicated esp32. Further sensors are planned.

I got the connection, although the Stop_bits 2 was a bit irritating, all other solutions have 1 stop-bit, as far as I remember.

Currently, the esp is not yet integrated in my HA system, as that is in a different subnet, but planned with a pi4 in the RV.

I do get some CRC errors, see below in my mqtt-messages. But as far as I can tell, all messages received reflect the status of the Truma.

Many thanks again, and if I can get you any further information, please let me know. Best Jens

Fabian-Schmidt commented 1 year ago

Thanks for the feedback. Is this log recorded via wifi or serial logging?

Also can you please sent the log output of the StatusFrameDevice message. It should only be printed shortly after Esp boot up as it connects to the CP plus.

Mostly the CRC messages are no issue and highlight a timing issue. But the CP plus is repeating messages multiple times. So if Esp does not get everyone is not ideal but no big problem.

Cheers Fabian

gmanic commented 1 year ago

The log is recorded wirelessly, via mqtt.

To get the serial output will take a couple days, as the esp is in my RV and I am still trying to figure a nice setup for the local (RV) homeassistant setup. I have two pi's alread in it (one for the Victron setup and one with OpenWrt for connectivity). Unfortunately, there's no "one-for-all" solution, yet. Maybe a pi4/8G with alpine-kvm/qemu plus three vm's might work.

But I'll try to get the serial output at the weekend, firing up the esp with my laptop connected.

Function test still to be done, as well. Good to know about the CRC messages.

Will keep you posted. :)

I hope it helps.

First invocation via HA failed somehow. And worked as well. :) My Truma setup is currently set on electric only (gas being worked on). As such, the Truma has been set to Electric1 (900W). That was (correctly) reported in HA. When I set "room temp" to 18°, the setup switched to Gas (which failed with error "no gas" - and the error was correctly reported in HA). I did not systematically follow up on my next steps via HA (multiple times pressed the button for Electric1 (900W), to no avail.

After I switched to electric-only via the Truma-display, setting the room temperature worked and my Truma came to life, doing what it was said. Same goes for "off" or "room temp 5°".

Now it may take some further time on testing (I would like to be there to see/hear the response of the heater).

The default yaml includes the web component: You should be able to get to the debug log from the ESP's web interface (IP address), No need to directly connect to it.

gmanic commented 2 weeks ago

Phew, what a year (first year off work, lots of car meets all over, even less time :)

Anyway. After my first ESPHome-Setup failed (after replacing it I had to realize that the ESP to LIN GND connection was somehow broke) I replaced it with a new setup.

It works. I get all necessary information in HomeAssistant, I can set room temperature and my Truma Combi 4E works on gas. (meanwhile installed, as well). Have not tested electrical heater, yet.

But I really have to stress that the GND connection from ESP32 to the LINbus module is absolutely essential, recheck and re-recheck that this is ok.

CRC errors are far less, but still there. As Fabian mentioned, this is due to timing issues.

Can timing be improved? I already disabled serial logging (baud_rate 0), what else can be removed or re-organized to improve timing for LINbus reading/writing?
