Chapter 7. Sending Notifications from the ESP8266
In this chapter, we are going to see how to integrate a very important element of the IoT with the ESP8266: notifications. IoT devices constantly alert users when something significant is happening, or simply at regular intervals, for example to report data.
We are going to see three scenarios in this chapter. First, we'll see how to send simple e-mail notifications from the ESP8266. Then, we'll learn how to make the chip regularly send data via text messages to your phone. Finally, we will see how to send alerts via push notifications. Let's start!
