Domoticz

Hello,
I've just updated my domoticz running on Synology DSM 6.2 to v2020.2.
Before the upgrade I exported the DB, then imported in new version.
The rfxtrx433e doesn't work, due to error "RFXCOM: Error opening serial port!".
In HW devices setup I'm seeing the rfxtrx433e, on serial port /dev/ttyUSB0.
I noticed that trying to insert again the rfxcom devices, nothing appear in the menu "serial port".
However the rfxcom is recognized by DSM (command lsusb ).
Can you help me?
Thx

Hello,
I think I have the same issue, but not sure. I use DSM 7.1.1. I used RFXcom connected on usb0 port and all worked well for several months. I used to connected to my Domoticz data with my smartphone. I was in holodays for two weeks and suddenly I got an error on Domotiz App : Oops, an error occur.
Going back from holidays, I wanted to check the Domoticz configuration and I did not get any devices. I tried to restart the RFXcom but not worked. I forced the USB driver (/dev/ttyUSB0 ) with a schedule task but no work too. I always get the following error: Error: RFXCOM: Error opening serial port!
I tested the rfxcom on computer and I can connect to it and see the devices.
Any help is welcome
Best
