Hatch Sound Machine Mod for Home Assistant Integration

Modify the Hatch White Noise Sound Machine so that you can control it from Home Assistant. Basically you only need to simulate touching the top metal ring as this serves to function as the "favorites" selector and the power button. I was not able to simply run the metal ring touch wire through the long wire leading to the relay as this messed with the capacitance and effectively disabled the touch sensitivity. So by placing a transistor in there, I was able to localize the switching. To operate, close your IoT relay for half a second to select the Hatch Favorite, then close the relay for 4 seconds to turn the Hatch off.
