Testing the human interface

As we have added chat interfaces, we can begin by testing our devices using any instant messaging client supporting XMPP. If you don't already have one, download one, create an account using an appropriate broker, and connect to your newly created devices, by adding them to your roster in your chat client. The devices should automatically accept your requests. Then start chatting with them. Figure 3 shows an example chat with the sensor. You can also chat with the actuator, and control its output using the chat interface. Check the menu to see how to do that:
