For many years, smart home applications have played a major role in our households. Real-time monitoring everywhere via the web, retracting the awning at sunset or lighting tasks by movement: the versatility and flexible adaptation is normally reserved for more expensive systems.
The aim of this thesis is to develop a radio board that offers the possibility to integrate all devices in the frequency range of 433 MHz due to a learning function except modules using rolling code or hoping code. Furthermore, a software interface to the programming language Scratch was developed, with which children and programming beginners can already program simple smart home applications without prior knowledge.
In addition to the hardware and software requirements, the design of the circuit on a breadboard, the test of the prototype and the implementation of the software are described in this thesis. Finally, a simple smart home scenario will be programmed with the visual programming language Scratch.
