In a Profoto YouTube video, the instructor had a setup where two Profoto B1 flashes were triggered with a Profoto AirRemoteTTL on the hotshoe of the camera but then he wanted to add a small Canon speedlight to the mix so he connected a PocketWizard PlusX to the Canon speedlight and another PlusX to the sync port of the camera and when he took the next shot the Profoto B1s got fired by their own AirRemote and the Canon speedlite got fired by the PlusX.
I was not able to do what he did at home; my PocketWizard one did not fire. So my question is do you think I understood what I saw in the video correctly and if it is possible at all? and if it should work then why I couldn't do it at home and What should I troubleshoot?
Here is the video, Minute 29:00: https://youtu.be/FY9QH-K-A0A?t=29m
