Stopping/Starting white noise without the app

Hi,

We regularaly leave the white noise on all day because we may not have our phones to hand to open the app and turn off the white noise. It's also a bit of a faff clicking through the screens, waiting for it to load etc.

What would be great, is something like a physical button to just press to turn on/off the white noise, that could be located in the babies nusery. 1 click, no hastle.
