Can’t pair Somfy IO

This screen doesn’t really tell us anything other than Bond thinks it set something up.
During Bond’s setup if the Somfy device fails at the step after the jog, from what I think I understand, the pairing failed - but Bond doesn’t really have a way to know that?

You didn’t happen to either buy the house with these already installed, or get them used / open box / demo unit, did you?
I recall this old post from a former Bond staff member:

The community member in that thread seemed to have success after factory resetting the Somfy, setting up the physical remote, then setting up Bond.
