Here is a smart fan that you can program using a smartphone or tablet to circulate up to 65 CFM of conditioned air without consuming too much power. The PAX doesn’t make a whole lot of noise and can be installed through the wall. It has 5 preset profiles but you can make further adjustment through the PAX app.
The fan noise is rated at about 20dB @ 10ft. Each PAX has its own unique ID, so you can control hundreds of these fans from a smartphone or tablet. This could prove useful in tiny homes, garages, and even boats.[where to find it]
