For large-scale wireless networks, the deployment of new systems can be a costly and tedious task. In this article we show how this effort can be reduced by automating the configuration of new wireless devices, based on their location. This technique is useful in e.g. home automation systems where a light switch needs to be paired with the light fixtures. To show how our system works, we have implemented a demonstrator application based on Bluetooth Low Energy. We assume that each room contains a beacon node that holds the settings for that room. Based on the RSSI in the BLE advertisements of those node, a new node can detect in which room it is deployed and update its own settings accordingly. A node can do this correctly in 96% of the case. To improve the reliability, a node can ask the user to confirm its position, whenever there is doubt. This happens in 12% of the cases, resulting in 100% correct localizations.
