Setup a proof of concept (Victron MultiPlus + Seplos BMS)

syssi commented 1 year ago

The idea:

The state of the Seplos BMS is retrieved periodically using RS485.
Selected/Required measurements are passed using CAN Bus to a Victron MP

@Meli73 Thanks in advance for your support!

[ ] Create a capture of the CAN bus traffic
[ ] Get an idea about the used protocol / registers and measurements
[ ] Make sure this implementation is able to pass the same informations via CAN bus
[x] Add an example of the schematics to the docs (ESP32 <-> CAN)

perheps also this part is OK: https://www.google.com/search?q=Sn65hvd230&rlz=1C1GGRV_enDE770DE770&sourceid=chrome&ie=UTF-8

So to the Schematics: We need two GPIO for RS485 and the same for CAN .
What 4 GPIO do you prefer ? so I could make a little drawing.

syssi commented 1 year ago

Let's pick GPIO16, GPIO17, GPIO18, GPIO19. I guess the SN65HVD230 is a good choice too!

Meli73 commented 1 year ago

Let's pick GPIO16, GPIO17, GPIO18, GPIO19.

WMOS D1 Mini only has 16 GPIO. So 13+14, 15+16 is OK, too ?

syssi commented 1 year ago

Are you talking about a ESP8266 or ESP32? We should stick to a ESP32 for now because the ESP8266 doesn't provide native CAN support. If you want to use a ESP8266 the MCP2515 must be connected via SPI.

Meli73 commented 1 year ago

Oh, yes .. so lets stay at the ESP32

grafik

I hope this is now correct

syssi commented 1 year ago

Good job! Could you provide this sketch in ASCII? :-)

Meli73 commented 1 year ago

I try already. But formating get's corrupt each time I do. no matter if in Readme.md or here

seplos CAN.txt ok .. this way ;-)

syssi commented 1 year ago

Thanks a lot! Let's focus on the traffic capture as next step.

How many devices are attached to the CAN bus?

only the seplos BMS and the Venus OS GX device (running on a RaspberryPi)

syssi commented 1 year ago

Is this your final setup too? We don't talk to the victron inverter directly? There is always the GX in between?

Meli73 commented 1 year ago

yes. that is the communication unit of the Victron Multiplus II inverter. It could be integrated in the inverter - or stand alone.

As next step I would like to add your ESP32 as third device to the bus. We could print some received frames to the log to make sure the setup works as expected.

Still Waiting for my hardware - namly the CAN transceiver... ;-)

Meli73 commented 1 year ago

back again .. sorry for the delay- my littel free time was fully blocked by getting my 2nd Seplos Mason Pack build up and running at all.

So I'm not at this - not so nice- point that I could monitor this 2nd Pack nicely by RS486 up into HA. But I'm nearly blind depending my frist Pack now. In the meantime, I hade also long and hard thoughts about the approach here with the "rebuild" master by listening and reverse engineering.

But I am now a little afraid to change the complete battery control to such a system - including some of the limitations and emergency shutdowns.

What if we only see the normal case but can't reproduce special cases and disturbances because we have never seen them?

Isn't the bluetooth approach possibly the better one at all? At least it would be much more passive and not so risky.

@Meli73 Could you contact me (syssi#5175) via Discord?

zekeboz commented 3 weeks ago

@Meli73 did you end up trying the BT approach? I am looking to do something similar but with 5 packs.
