Help Needed! (RFlink + Ubuntu 16.04)

[Goudtik]

I don't seem to get it...

I had Domoticz running on my Rpi3 connected to 2x RFlink devices (1x 433mhz and 1x 866mhz). Everything worked fine.

Recently I installed Domoticz on my Ubuntu server and connected both of the RFlink devices. When I view the log in Domoticz I see that both of the devices report that they are running firmware v46 and Domoticz seem to detect all of the devices in the area.

BUT when I activate or deactivate a switch in Domoticz nothing happens! (Domoticz comfirms that, for instance, the light is turned on, logs this event in the eventlog (no error).
The RFlink devices do not seem to transmit anything.....
I thought that this could have something to do with the user which it is run on.

I have a seperate user named 'domotica' with no root privilages. Domoticz runs under 'domotica'.
'domotica' is a member of the group 'dialout'. Both of the RFlink devices (connected as /dev/ttyACM0 and /dev/ttyACM1) are also dialout-member.

What could I try next?? Any suggestions would be appreciated!

First install the latest firmware (rev47) and make sure with rflink loader that your device is able to transmit.
