The Philips Hue Dimmer Switch (sold by Philips Hue Australia as the "latest model" and by JB Hi-Fi and Officeworks as the V2) is a small battery-powered remote that sits on a wall plate. Philips Hue describes it as "battery powered and wireless, so you won't have to do any rewiring", which makes it a surface-mounted accessory rather than a switch an electrician installs behind the wall plate. The plate attaches with the included adhesive backing or screws, and the switch itself lifts off to use as a handheld remote or to stick to a magnetic surface such as a fridge.
The layout is an on/off button at the top, dimming controls, and a Hue button at the bottom. Philips Hue says the Hue button can be set to trigger different scenes based on the time of day, cycle through favourite scenes, turn lights off or start and stop automations.
Bridge or no bridge
This is the key buying question. Philips Hue's setup guide describes a "connect without a Bridge" path: hold the switch within 15 cm of a Hue bulb, press and hold on/off for three seconds, and repeat for up to 10 bulbs. The product page lists Bluetooth and Zigbee as its communication protocols. However, Philips Hue states "a Hue bridge is required" to change how the dimmer controls your lights, and the larger features, such as controlling up to two Rooms or a Zone, are described with a Bridge in mind. Philips Hue also lists Alexa, Google Home, Apple Home, Matter, Samsung SmartThings, IFTTT and Sonos among its third-party compatibility, so a Bridge-based Hue system is the natural fit.
It suits renters, since nothing is wired, and anyone who wants a switch next to a lamp or bedside. Skip it if you have no Hue lights: it is designed to control Hue bulbs and fittings, and for non-Hue lights a wired smart switch is the better route.
Australian notes and running costs
Because it is battery powered and wireless, it does not connect to your 230-240V household wiring at all. Running costs are one CR2032 coin cell, which Philips Hue includes and rates for a minimum of two years. There is no subscription mentioned on the Hue page. JB Hi-Fi and Officeworks both list the V2 in Australia.
