Wireless Aluminium Light Switch Valena Next with Netatmo

The Legrand Valena Next with Netatmo 741843 wireless light switch lets you add a new control point for lighting and other connected devices without the need to run electrical wiring to the mechanism. It features an elegant aluminium finish, has an ON/OFF button, and operates with a replaceable 3-volt CR2032 lithium battery.

This wireless control is designed to integrate into a Valena Next with Netatmo installation and can be paired with connected lighting switches, micromodules, power sockets, and other compatible products. Its ultra-slim format allows it to be installed directly on the wall using the supplied adhesive pads, creating new control points without chasing walls or modifying the existing wiring.

Valena Next with Netatmo wireless switch in aluminium finish

Reference 741843 is part of Legrand's connected Valena Next with Netatmo range. It is designed as an additional wireless control that allows you to control already installed connected products in the home.

Its main advantage is that it does not require wired power at the installation point. As it runs on battery power, it can be placed in practically any compatible location, making it easy to create a configuration similar to a light switch without having to install new conductors between both points.

Wireless ON/OFF control

The Legrand 741843 features one ON/OFF control button. Once paired with the connected installation, it allows you to switch on and off the compatible devices linked to the control.

It can be used to add an extra control point for:

• Connected lighting switches.
• Connected lighting micromodules.
• Connected power sockets.
• Other compatible Valena Next with Netatmo devices.

Depending on the configuration set up in the installation, it can also centralise the control of several compatible products with a single press.

Ideal for adding a second control point without cables

One of the most practical uses of the wireless switch is creating new control points without renovation work. It can be used, for example, to add a second lighting control in a room where there is only one connected switch.

As it does not require power or communication cables in the mechanism itself, there is no need to chase the wall or run new conductors to the new control point.

Wireless communication via Zigbee

The control uses 2,400 MHz Zigbee wireless communication to integrate with compatible devices in the connected system.

Legrand specifies a radio range of up to 185 metres for the product under the manufacturer's reference conditions. The actual range inside a home may vary depending on walls, building materials, obstacles, and installation conditions.

The communication system incorporates 128-bit encryption and variable code for wireless transmission.

Powered by CR2032 battery

The switch operates with a 3-volt CR2032 lithium battery, included with the product and replaceable when depleted.

Legrand indicates an estimated battery life of up to 8 years under normal use conditions. As it runs on battery power, the control does not need a phase or neutral conductor at its location.

Low battery LED indicator

The mechanism includes an LED indicator that operates during installation and warns when the battery level is low.

This indication makes maintenance easier and helps identify when the CR2032 battery needs to be replaced before the mechanism stops working properly.

Ultra-slim mounting directly on the wall

The Legrand 741843 has an ultra-slim design with only 12 mm depth. It is designed for surface mounting and can be installed directly on the wall using the supplied adhesive pads.

The adhesive elements also allow the switch to be repositioned, providing flexibility if you later want to change the location of the control point.

Can also be installed on a universal box

In addition to adhesive mounting, the control can be fixed to a universal flush-mounting box using screws. The screws required for this mounting option are not supplied with the product.

This option is practical both in new installations and in renovations where an existing electrical box is to be reused.

Full 83 x 83 mm format

The mechanism has compact dimensions of 83 mm width, 83 mm height, and 12 mm depth.

Legrand supplies the product complete with the elements needed to maintain the Valena Next aesthetic, including the corresponding aluminium front finish.

Valena Next aluminium finish

Reference 741843 uses the characteristic aluminium finish of the Valena Next range. This finish allows the wireless control to be combined with other lighting mechanisms, power sockets, and connected devices from the same series to maintain a consistent look throughout the installation.

The ultra-slim design and absence of visible wiring also make it easy to integrate into different rooms in homes and commercial spaces.

IP40 and IK02 protection

The wireless switch has an IP40 protection rating and IK02 impact resistance.

It is intended for indoor installations and has an operating temperature range of 5 to 45 degrees Celsius.

Requires a Valena Next with Netatmo installation

The Legrand 741843 is an additional wireless control and does not work autonomously as a conventional electrical switch.

To add it to a connected installation, you must already have a Valena Next with Netatmo Starter Pack or a compatible gateway, as well as one or more connected products that the control will operate, such as switches, micromodules, or power sockets.

Integration with Home + Control

The switch is part of Legrand and Netatmo's connected ecosystem, managed through the Home + Control app.

A correctly configured Valena Next with Netatmo installation allows you to combine wireless physical controls with the connected functions available in the system, including smartphone control and functions compatible with voice assistants.

The exact availability of each function depends on the connected devices, the gateway, and the configuration set up in the installation.

Pairing with connected products

The control is designed to be easily paired with compatible wired Valena Next with Netatmo products. This makes it possible to expand an existing installation later by adding new wireless control points.

This modularity allows you to modify or expand the layout of the controls without necessarily altering the existing electrical installation.
