Shelly 2-Output PowerBase for Wall Display – Replacement Base with 2 Independent Outputs (Dual Relay), Flush-Mounted, Hardware Accessory for Shelly Wall Display

The Shelly 2-Output PowerBase is a specialised hardware accessory (flush-mounted power supply base) designed exclusively for the Shelly Wall Display smart screen. This module replaces the standard single-output base included in the display package, providing instead two fully independent physical relays. It is the ideal technical solution for upgrading, allowing installers to use the Shelly Wall Display console in place of a traditional double switch, controlling two separate electrical circuits directly from the same wall box.

Key Features & Technical Benefits

• Upgrade to Dual Relay (2 Outputs): Transforms the display’s switching capability from a single relay to a dual relay. You can wire and physically control two independent lighting circuits within the same room.

• Direct Hardware Integration: The Shelly Wall Display is mechanically secured and electrically connected to this base via contact pins, instantly recognising the second output in the graphical interface and in the Shelly Smart Control app.

• Energy Measurement and Monitoring: The base unit incorporates power consumption measurement circuits for both channels. It monitors electrical activity and transmits data in real time to the display and app for accurate cost analysis.

• Advanced Safety (Gen3 Tech DNA): Includes strict hardware protection against overvoltage, overcurrent and overheating. If safety parameters are exceeded on either of the two channels, the power supply is automatically cut off.

• Standard Flush-Mount Installation: Designed to fit into standard European (round) flush-mount boxes. Requires a neutral (N) wire to power the electronic components and the touchscreen.

Examples of Applications

1. Replacing a Double Switch: Allows the touchscreen to be fitted into the existing socket in the living room, whilst retaining physical control via a cable for two different lighting zones (e.g. the main chandelier and ambient spotlights).

2. Air Conditioning or Ventilation Control: One channel can operate a solenoid valve for underfloor heating, whilst the second channel controls a ventilation system or a secondary lighting circuit.
