Air flow sensor

hi,

I would like to “follow” (monitor) the air flow in a building. Any idea how to do this?

I was thinking with an air pressure sensor but I have not found any working on wifi (with web or mqtt).

TIA for any help or starting point!

Did you ever find a solution for this?

Were you looking only for wifi? --Had you found any airflow devices using other protocols --Bluetooth, Zigbee, Z-Wave ?
