Summary
In this chapter, we learned all the basics about sending automated notifications from your Raspberry Pi. We learned, for example, how to send notifications via email, text messages, and push notifications. This is really important to build a smart home, as you want to be able to get alerts in real-time from what's going on inside your home and also receive regular reports about the current status of your home.
You can of course improve the projects of this chapter in many ways. It would be easy for example to have several Pi Zero boards in your home, each sending you alerts on your phone for example. You could give a name to each of the boards and include that name inside the alerts so you know which Pi sent the message.
In the next chapter, we are going to use everything we learned so far in the book to build a simple security system using the Raspberry Pi Zero board.
