Is it just me or are they pressing some sort of a tiny reset button? Could be something related to the WiFi functionality.
Another thing I noticed was the way to connect to the fixture, it isn’t done through a regular network scan, but rather abstracted through the app.
While it doesn’t necessarily mean anything, it also opens the option of having a hidden SSID, meaning the access point will not be visible when you scan it, and in order to be able to connect you will have to actively look for the SSID or even the BSSID (thigh less likely).
One could try to sniff beacons with a monitoring capable card like Alfa, but I think that would be completely out of reach for him.
Another thing that concerns me is the fact that it needs an app, and the video is 8 years old. While some old apps are still available and working, there is no guarantee this one is.
