Just to be clear, my understanding of news here is France is that there is an investigation for someone having possibly rigged the weather sensor but there was nothing release about how this could have been done.

The hair dryer thing is a joke, even if it is still a possibility, but just to say, it could be a cover, it could be a hot air gun, it could be a hack, it could be just luck, ...

Take care because there are ai generated videos of a guy with a hair dryer doing that, but these are fake!
