Domoticz

How do I do this?

I plug the RFXtrx433 in, it flashes red then amber and that's it, Windows doesn't do anything and in the latest RFXflash it just no com port found.

It's normally attached to a Raspberry Pi running Domoticz but I try that in the IP I get SocketException:10061 No connection could be made because the target machine actively refused it x.x.x.x:10001

For Windows, I think the RFXcom site has a link to some USB drivers.

Not unless it's buried somewhere else, perhaps hidden in RFXmanager?

Ok found it mentioned in the RFXmanager user guide pointing here http://www.ftdichip.com/Drivers/VCP.htm

Yup added driver and sorted now

Although in Domoticz I'm fairly sure it used to say the firmware version and now it doesn't or just says version 1

My fresh Windows 10 installation does not recognize the RFXtrx , despite installation of ftdi drivers
