To answer my own question, if you have the same setup (Louvolite electric blinds with Vera Edge and RFXTRX433E), this is my setup:
Vera Edge:
firmware - 1.7.3917 (latest current version is very buggy 1.7.4832)
RFXtrxPlugIn 1.87 -
Plugin Update V1.87
RFXTRX433E - latest current EXT version 1025 -

The issue I was having was my pairing method was incorrect, with the Lightwave switches I put the switch in pairing mode (press both on and off buttons together until they start flashing) then send an on or off command from Devices. See Pic1, this paired the RFX with the switch.
For pairing with the Louvolite blind motor just add the device first (Devices / RFXtrx / New Devices), I tried both Hasta New and Rollertrol categories as my device didn't have the Louvolite option, both work. After adding the device, just click back, then Managed Devices, if you can't see your new device then click refresh table.
PS. If your screen hangs on adding new device like it does on mine, don't worry just give it 5 seconds and click on devices, it will be added anyway. Its just a bug in this firmware.
It should be listed as per pic2, select your device, on the Command select Confirm/Pair, put the motor in pairing mode by pressing down the red button until it jogs slightly, then press the Run button - you should see/hear the motor jog confirming paring action complete.
Provided you have set your upper, lower and middle limits you don't need to do this again as the motor remembers these settings.
Next stage is setting up scenes and then connecting to Alexa / Google Home which is the stage I'm at now!
