Wireless Dimmer Switch
Philips Hue Dimmer Switch Review

Up to two Rooms or a Zone  |  1 x CR2032 battery  |  Zigbee and Bluetooth  |  10 lights without a Bridge  |  Indoor, IP20

Overview

The Philips Hue Dimmer Switch covered here is the one Hue sells as the Dimmer Switch (latest model). It is a white, battery-powered wireless switch with four buttons (per Hue’s US FAQ); Hue’s UK page names an on/off button at the top, a Hue button at the bottom and two buttons for dimming up and down. Its buttons can be set to trigger lights or automations, and Hue says a dimmer switch can control up to two Rooms, a Zone or your entire lighting setup. With a Hue Bridge it handles up to 50 lights. It measures 125 x 80 x 15 mm.

It runs on one CR2032 battery, which is included, so there is no rewiring. You fix the wall plate or mounts to any flat surface with the included adhesive backing or with screws. It uses Zigbee and Bluetooth and is set up in the Philips Hue app (Android 12.0 or above, iOS 17 or later). Hue’s FAQ says it can control up to 10 lights without a Bridge; add a Hue Bridge to change what the buttons do and to control up to 50 lights. It is rated IP20 for indoor use and works from 0°C to 40°C.

Good to Know

Hue sells this switch as the Dimmer Switch (latest model). Hue says the current version has an on/off button at the top and a Hue button at the bottom, so check for that layout when you buy.

Setup & Installation

Add the switch in the Philips Hue app: go to Settings > Devices and tap the + button. It is battery powered and wireless, so there is no rewiring; fix the wall plate or mounts with the included adhesive backing or with screws.

If it stops responding, check the CR2032 battery first; Hue’s US FAQ says low battery voltage often causes delayed responses or flickering LEDs. Next, use Reset on the switch’s edit screen in the app. If problems continue, press the setup button/pinhole for more than 10 seconds, then add the switch again in Settings > Devices.
