Are the Legrand frames included in the set?

No. The box contains the Shelly BLU Wall Switch 4 switch and the adapter for Legrand Niloe and Shelly frames. The frame itself must be purchased separately or you can use one already installed.

Which frames is the adapter compatible with?

The supplied adapter is compatible with Legrand (Niloe series) frames and Shelly frames, allowing the switch to be neatly fitted into an existing row.

Is electrical wiring needed for installation?

No. The switch is wireless and powered by a CR2032 battery, so it needs no 230 V mains connection and no wall chasing is required.

How long does the battery last and what type is it?

The device uses a 3 V CR2032 battery (included) with a life of up to 2 years depending on usage.

How many buttons does it have and what can it control?

It has 4 buttons, each with single, double, triple and long press — up to 16 actions for lighting, blinds, garage doors and smart-home scenes via the Shelly ecosystem with a Bluetooth gateway.

What is the Bluetooth range?

The range is up to 30 m in open space and up to 10 m indoors; in buildings with concrete walls it works reliably within one or two rooms near the gateway.

About this product

The Shelly BLU Wall Switch 4 is a wireless four-button switch that runs on the Bluetooth Low Energy (BLE) protocol and is powered by a single CR2032 battery with a life of up to 2 years. The device needs no electrical wiring: it can be fixed to the wall or used as a portable remote to control smart-home scenes, lighting, garage doors and blinds.<br><br>What sets this bundle apart is the in-box adapter for Legrand Niloe and Shelly frames. The adapter lets you neatly fit the switch into an already-installed Legrand Niloe frame so it matches the other mechanisms on the wall. The frames themselves are not included — you need an existing Legrand Niloe or Shelly frame.<br><br>Each of the 4 buttons supports single, double, triple and long press, giving up to 16 actions to trigger scenes and automations in the Shelly ecosystem through a Bluetooth gateway.

Where it works

Use cases

In a Chisinau apartment one button starts the evening scene: dims the light and lowers the blinds.

Battery-powered wireless switch to trigger smart-home scenes.

A smart button is added next to ordinary Legrand mechanisms without changing the row design.

The adapter fits the switch into an already-installed Legrand Niloe frame.

The button is kept by the bed to turn off the lights across the whole home before sleep.

The device works unmounted as a Bluetooth remote.
