Seplos / EEL RS485 to USB Cable
maxpd1 opened this issue · 9 comments
Hi,
according to the comment 25th of July the cable, which was part of the EEL 48V DIY battery case, should be usable: https://community.victronenergy.com/questions/196594/seplos-bms-mars-battery-case-wie-mit-raspberry-ven.html
But do I miss a step?
I installed all required packages:
I tried to install 2 different drivers for the adapter:

But I don't see services or devices and the cable isn't flashling as it does when there is a successfull data transfer with a windows PC.

If you add serial numbers and they aren't included in the information provided by the interface, they will NOT be activated. If the devices do not have a serial number then you can have at most ONE of that device type and you should not enter any serial number.
I am not sure if the device has a serial number. At least I can't find any.
So I deleted the ports and installed it again without serial number.
But I still don't have luck.
I only went with custom device as this was the only option which recognized a USB device.
By selecting a custom device type, the script will attempt to find devices that MIGHT be a CANbus interface and report that to you. If recognize the interface by what is provided, the script will build a configuration based on what is shown. If nothing is detected, you will need to provide some way for the dev rules to identify the device either by device id, vendor id, model number or serial number. You will need to get this information from the device's documentation (if provided) or by inspecting the port information reported in dmesg.
If you select a device that is supported by the script, most of the necessary information is filled in for you.
If you have multiple interfaces, some way of uniquely identifying each is essential.
It may be that the device you have is not actually a CANbus interface but actually requires a separate interface.
sorry if I have to ask further questions.
how do I maintain the dev rules respectively provide the necessary information to the system?
was it last of your readme? if yes I am so sorry that I didn't find it.
in my log above lot of your started information were recognized by the system.
idVendor=0424, idProduct=9514, bcdDevice= 2.00
ok, it got more cleare to me with dmesg
I repeated the process and took the following usb device with serial number and so on.
There is only one USB port used on the raspi.
But unfortunately I still get no date.
I am using the RS485 port instead the can (I tried both several times) as described in the user report mentioned in first post.

I believe your issue is that the BMS is not providing a CANbus equivalent over the USB cable you are using. If you have Cerbo, it has a full function CANbus port as well as one dedicated for use with a BMS. As others have described in the article you linked at the begging of this thread, this needs to plug into the CANbus port on your BMS/battery case with the appropriate cable -- all mentioned in that other thread.
For other platforms you may need to purchase a CANbus interface such as the Canable one I used for a while when running Venus OS on a Raspberry PI. It plugs into a USB port on the GX device and then with a home-made cable into the BMS CANbus port.
ok, maybe I should buy a canable. I just wonder why the last comment in the linked topic uses successfully same cable with same BMS and same Venus os on raspi
only to be sure. can you link the canable you used successfully?
btw. I saw in notification that you left a comment in the victron forum in the linked topic. but your comment isn't visible.
The one I used was the CANable Pro but is currently showing as sold out.
There is a 2.0 version that is not isolated like the Pro is.
To be stable, you need to reflash with Candlelight firmware. Candlelight is GS USB.
slcan software will sometimes work but Victron reported dropped packats with it.
There are also several USB CANbus interfaces listed at Victron that should work:
