The Shelly 2 Output Power Base for Wall Display is a practical replaceable power supply and relay module specifically designed for the Shelly Wall Display X1i and X2i smart panels. The module allows the Wall Display to function not only as a control panel but also to directly control two separate electrical circuits, such as lighting or other electrical loads.
The device operates as a power supply module connected to the back of the Wall Display, offering a space-saving and integrated solution for installation into standard wall boxes. Thanks to the two built-in relays, up to two separate lighting circuits or other devices can be controlled from a single compact and smart unit.
Using the relays, lighting can be remotely switched, automated, or scheduled, while the Shelly Wall Display serves as the central user interface. The system also supports local operation, ensuring reliable functionality even without an internet connection.
Its compact design makes it especially suitable for apartments, hotels, smaller commercial spaces, and modern smart homes where aesthetic appearance, minimal space usage, and multifunctional control from a single wall-mounted unit are important.
