Using a Leica (006) and a Pocketwizard

Your question is a bit confusing.

When you say “Profoto airplay” do you mean Profoto AIR Transceiver or Profoto AIR Sync?

Profoto AIR and Pocket Wizard are not compatible. One cannot trigger the other. Only Profoto AIR Receiver is built into the B1,
which means you will need a Pocket Wizard plugged into the Profoto B1.

So yes, you will need three Pocket Wizards. One at the camera, one plugged into the B1, and one to use as the remote trigger.

I think you could have just got one Profoto AIR Sync to act as a remote trigger because you already have one for the camera,
and AIR Receiver is already built into the B1.
