I’m running home assistant OS in Proxmox with full USB passtrough. (7.2-4) on a intel NUC
When i try to add my P1 (DSMR) USB Serial convertor it will eventualy time out. (cannot connect)
Manual specify the post doesn’t help
Any help?
@davemenkehorst I had alot of issues with a conbee 2 stick … some times it worked sometimes not…
what you could test - if you have a spare usb3hub somewere … try to have this passed an then attach the ftdi serial adapter…
I had to convert on machine to a dedicated host… just for HA - so did not find an ideal passtrough solution…
sorry
So it’s not possible to use a serial device(like a DSMR) via Pormox passtrough?
It should be, I have multiple USB devices passing through to Hass in a proxmox VM.
Can you show the config? (it’s in /etc/pve/qemu-server )

# info usbhost

That looks fine, the only thing I can think of is to try and pass the port by id instead of “full port”. You could give that a try. Delete the USB mapping create a new on and use “Use USB Vendor/Device ID” instead of “Use USB Port” and see if that does work.
Yes i tried al the options. Also on usb 2 ports and usb 3 ports.
Home assistant detects the usb p1 cable just fine. Only it hangs when i try to add it as an DSMR intergration
Little bump. Any DSMR developers around?
A little bit late to the party and also not a developer, but I had exact the same problem and fixed it. In my case it became clear the P1-cable wasn’t fitted correctly to the utility meter. I had a splitter to accomodate for an extra P1-meter from the electricity company (zonneplan). When I was redoing the wiring I found the connection was wobbly. After making sure the connection was OK the P1-integration worked almost instantly. Hope this helps.
I followed this:
after reboot host and changing usb to “Use USB Vendor/Device ID” it became visible in HA as /dev/ttyUSB.
