RFXCOM RFXtrx via ser2net stops working after several hours

bolderbast · January 4, 2021, 11:00am

Hi,

This is my first post here. I have been running Domoticz previously and have now completely switched to HA. Love it so far! Way more options and integrations, and a lot more active development and community!

I have searched for “RFXtrx ser2net” but could not find a solution to my issue, so I figured I’d start a new topic. If I missed a topic which discusses this exact issue and configuration, please point me to it and accept my apologies.

Here’s my issue:

I am running HA in a VM on my main server. I have a Raspberry Pi 3 with APC UPS, Aeotec Z-wave stick, DSMR and RFXCOM RFXtrx devices connected. On the Pi I have ser2net running for connecting my DSMR and RFXCOM RFXtrx to HA on my main server.

This all runs well, except that after several hours, my RFXCOM RFXtrx entities don’t get updated anymore. DSMR is still running fine and keeps updating. Reloading the RFXCOM RFXtrx integration does not help, but completely restaring HA makes the RFXCOM RFXtrx entities work again for several hours, until they stop again and I have to restart HA again…

I don’t have to restart ser2net to get it back working again, so my guess is that there is an issue with the
RFXCOM RFXtrx intergration of HA. But that’s just a guess.

HA Version: 2020.12.1
Ser2net version: 4.2.3
Ser2net config (/etc/ser2net/ser2net.yaml):

connection: &dsmr
  accepter: tcp,2001
  timeout: 0
  enable: on
  connector: serialdev,/dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A139GPQL-if00-port0,115200n81,local
  options:
    kickolduser: true

connection: &rfxcom
  accepter: tcp,2002
  timeout: 0
  enable: on
  connector: serialdev,/dev/serial/by-id/usb-RFXCOM_RFXtrx433_A121JBDO-if00-port0,38400n81,local
  options:
    kickolduser: true

I hope someone can help me with this issue!
I can’t find enything relevant in the logs, but if there are specific logs/debugging to check, please let me know!

Thanks in advance!

No response yet, but hopefully that will still come…

In the mean time I have started Home Assistant with debugging enabled for RFXcom. These are the last lines of the output before it stops working:

I’m experiencing the same issue.
Have you found the solution?

bolderbast · September 25, 2021, 8:58pm

No, didn’t find a solution to the root cause. Ended up using socat to map the remote connection to a fake local port. And then pointing the RFXcom integration to that local port. Has been working flawless for months now!

iganin · September 28, 2021, 5:13am

Thank you for the updated. It works for me too. Do you know how to launch socat at startup of the HA core?

iganin · September 28, 2021, 7:27am

@bolderbast Can you also share your socat command?

bolderbast · September 28, 2021, 8:10am

As said, I run Home Assistant inside my own Linux VM (running Arch Linux). I created a systemd unit to start socat:

> # cat /etc/systemd/system/socat.service 
> [Unit]
> Description=Multipurpose relay (SOcket CAT)
> After=network.target

> ExecStop=/usr/bin/killall socat

As an alternative you can also use USBIP to have a USB connection over network.
So for HA its a serial connection. Works fine for me.

Many thanks !

Same issue for me and your direction saved me a lot of time.
Have to wait some days, but seemed to be an elegant solution (for me).
