In this chapter, we saw how to send automated notifications from your ESP8266 to your e-mail, your phone via text messages, and via push notifications. This allows us to either send data back to our mobile devices or create alerts based on measured data.

You can of course adapt what you learned in this project to your needs, and create alerts coming from your ESP8266 (or from several modules!) that will let you know instantly about any changes in what you want to monitor.

In the next chapter, we are going to take everything we've learned so far and create a new project using the ESP8266: a door lock that you can control from the cloud.
