Summary
Let's summarize what we achieved in this project. We used the MQTT protocol to control an LED, a lamp or any electrical devices from anywhere in the world, via the ESP8266 Wi-Fi chip. We configured the ESP8266 as an MQTT client, and then connected to the aREST dashboard so we could control it from anywhere we are in the world.
There are many things you can do to improve this project. You can, for example, add more modules like this one to your aREST dashboard, to control all the lamps inside your home remotely. You can also add other devices, such as sensors, to your dashboard, which is what we will see later in this book.
In the next chapter, we are going to look at another very important topic in the Internet of Things: how to make our ...
