OK, so we have a functioning time display using Adafruit.io and the ability to turn your device on or off using the PyPortal touch screen or from a web page. We could be done here, this is a functional product as it stands. However, we just need one more step to enable the PyPortal to act on voice commands from an Amazon Alexa or Google Assistant. The magic to do this is done using the web site ifttt.com. This site, short for "If This Then That", connects the voice device with Adafruit IO. Configure one or both if you happen to have both types of voice assistants.
To begin, click the "Explore" button in the upper right of the page on the IFTTT web site. Next, click the "+" button next to "Make your own applets from scratch".
The first time you connect to a service like Amazon Alexa, Google Assistant, or Adafruit IO, you will be prompted to connect to that service with your login name and password.
Depending on the device you are using, continue with either the "Alexa Setup" or "Google Assistant Setup" page.
