Features
Sometimes less is more
GuSi is an Internet radio that specifically avoids unnecessary complexity. Reduced to the bare essentials, it offers maximum ease of use. It is perfect for anyone looking for a simple, reliable and intuitive device.
Customized transmitters
Instead of scrolling through hundreds of radio stations, the radio focuses on a predefined selection.
This means that the preferred stations can be accessed quickly – without searching or adjusting
Easy to operate
Just two controls are needed to operate the device:
A rotary control for volume and station selection, and a button for switching on and off.
Depending on the model, it is also possible to pause or switch directly between pre-defined stations.
Simple Wi-Fi integration
The radio can be integrated into the home network using the WPS function – with just two button presses.
If WPS is not available, the device starts its own hotspot. The Wi-Fi connection can then be set up using a smartphone or tablet.
Simple – not restricted
If something fails the radio will give you as much specific information as possible – for example, whether there is no internet connection or the network problem is located in the Wi-Fi. This makes it easier to find the cause.
Material costs
The material price alone (as of 2025) is around €100. The Raspberry Pi, the amplifier and the speaker make up the largest part.
If you want to save a little, many components can also be purchased cheaper from Chinese stores.
