This example demonstrates how to build a switch device to be used with ESP RainMaker.

- This example sketch uses the on board Boot button and GPIO16 to demonstrate an ESP RainMaker switch device.

- After compiling and flashing the example, add your device using the [ESP RainMaker phone apps](https://rainmaker.espressif.com/docs/quick-links.html#phone-apps) by scanning the QR code.

- Toggling the state from the phone app will toggle the switch state (GPIO16).

- Pressing the Boot button will toggle the switch state (GPIO16) and the same will reflect on the phone app.
