Not sure which one your are using, so not sure this will be of any help...
I have a Victron BMV-702. I used the VE.Direct Data Cable to connect it to my Raspberry Pi (Mac mini before that while testing). I installed the vedirect-serial-usb plugin and gave it an alias, as you stated, in the Serial App, signalk data.
In the plugin configuration, I set the USB Device to the alias (/dev/ttyOP_victron) and set the USB port to 7878 per the plugin info page instructions.
Hit submit, rebooted the server, and then checked Data Browser to see the electrical data coming in. That was it. Hope this helps. I assume the Venus plugin will have similar settings somehow.
