During the course of this chapter, we have tried to develop two simple applications. First, we have gone over all the C application development steps for a temperature sensor and talked about the importance of temperature data in home automation. We also measured relative humidity from the sensor, which it already calculates.

Then we discussed remote switches and tried to work on a device that exists in the market. In order to work on this remote switch, we included a controller sensor to communicate via the serial protocol with Intel Galileo. In order to make our application work with serial devices, we learned about building kernel modules for new devices attached to Intel Galileo.

Finally, we implemented functions to help us send and receive data from the serial Z-Wave controller and tried our samples to control energy consumption values from the remote wall plug.

In the next chapter, we will cover more on remote switches, that control light bulbs and lamp holders, and get more information on handling basic Z-Wave messages. While covering new devices, we will make our application more automated by adding threading capabilities.
