Domoticz

Hi all,
I'm hoping someone can help me get a new device paired to my somfy blind. I can see commands from the existing remote in RFLink Loader without issue, the RTS table updates from the existing Somfy remote, and using the hex number of my existing remote, I can send a command such as:
10;RTS;fbcb36;01;STOP
from RFLinkLoader to control the blind with success.
But if I try to pair a new device using the matdomotique guide as a reference, I have no luck. When I press the button on the back of the existing paired remote the blind jogs as expected, but if I then try a pairing command such as:
10;RTS;02FFFF;0412;6;PAIR;
to pair a new device, the blind does not jog and I believe has not successfully paired. I do receive a 20;xx;OK message and can see the entry in the RFLink RTS table, but am unable to send commands using the device.
I have both an off the shelf 433.42 nodo board/transceiver and a 433.92 and have tried both.
Any suggestions or workarounds would be gratefully received!
Many thanks
Tim

Can you try with an "slightly changed address" for the new remote?. In your case maybe something like fbcb37 or fbcb16.

I have read somewhere that the address can't begin with 0.
