In addition, the students should be able to work and try out as much as possible themselves – also at home. The control technology was therefore designed entirely with free software. The students can install the software on their own laptops.
A Raspberry Pi mini-computer with an uninterruptible power supply (UPS) is used for the control technology. The software used is openHAB with its own web server and a MariaDB SQL database, which enables manufacturer-independent home automation.
This means that the test stands can be controlled from the master computer as well as from a smart phone or by voice commands. Octave, also free software, is used to evaluate the monitoring data.
With hardware costs well under 100€, students can begin their own experiments in “smart” living. Perhaps this is how the smart student flat will emerge.
