Smart Dimmer Switches

Smart dimmer switches let lights be dimmed from a wall panel, a phone app or a voice assistant. This page holds Ajax SoloButton (Dimmer) touch front panels in colours such as Black, Grey, Ivory and Oyster, the Ajax LightSwitch Dimmer with its LightCore relay, which needs no neutral, and the Knightsbridge VFRKW smart Wi-Fi dimmer module, controlled through the SmartKnight or Smartlife apps and by Amazon Alexa, Google Assistant and Siri Shortcuts.

Choosing Smart Dimmer Switches

Decide first whether the dimmer joins an Ajax hub system or works on its own over Wi-Fi, then check the wiring in the switch box and the lamps it has to dim.

Ajax SoloButton panels and the LightCore relay

An Ajax LightSwitch dimmer is built from two parts. The SoloButton (Dimmer) is just the touch front panel: the White 91254.257.WH1, for example, will not switch or dim lights without the LightCore (Dimmer) relay installed behind it. The LightSwitch Dimmer with LightCore Relay supplies that relay, needs no neutral because it takes its power from the phase alone, and installs into a standard European (55) mounting box.

Touch, backlight and dimming control

Panels such as the Olive 98612.257.OL1 and Fog 98608.257.FG1 respond to a hand within 15 mm of the panel, and the Fog panel sets the level with a capacitive touch slider. The Black 98607.257.BL1 and Grey 98610.257.GR1 remember the last brightness level, and the soft LED backlight on the Ivory 98611.257.IV1 and Oyster 98613.257.OY1 can be switched off in the Ajax app. The LightSwitch Dimmer is compatible with incandescent, halogen and dimmable LED lamps rated 8-150 VA, and has a fuse, a software overcurrent trip and temperature protection.

Knightsbridge Wi-Fi dimmer module

The Knightsbridge VFRKW is a direct replacement smart Wi-Fi dimmer module in the offset position. It is controlled from a smartphone or tablet through the SmartKnight or Smartlife apps at home or away, and connects with Amazon Alexa, Google Assistant and Siri Shortcuts for voice control. Its timer switches and dims the lights on a schedule, the app can remove flicker and adjust the dimming curve, and it supports 2-way or 3-way dimming in conjunction with retractive switches.

Frequently asked questions

Can smart bulbs be used with a dimmer switch?

No, not usually. A smart bulb has its own dimming electronics, and a conventional dimmer cutting its supply can cause flicker, buzzing or loss of its wireless link. Keep that circuit at full power and dim from the app instead. A smart dimmer switch suits ordinary dimmable lamps. The range here includes touch dimmer panels and a Wi-Fi dimmer module.

Do smart bulbs need a dimmer switch?

No. Smart bulbs usually dim themselves, so brightness is set by app, voice assistant or wireless remote while the wall switch stays on. Turning that switch off cuts the power, and the bulb cannot respond until it is switched back on. A smart dimmer switch is the alternative if you want to keep ordinary dimmable bulbs and still control them remotely.

What is a smart dimmer switch?

A smart dimmer switch replaces a standard light switch and adjusts lamp brightness by touch at the wall and remotely through an app, voice assistant or schedule. Some connect through an alarm or smart-home hub, others over Wi-Fi. Check the load rating and that the lamps are dimmable before fitting. The range here includes Ajax touch dimmer panels, an Ajax dimmer with relay and a Knightsbridge Wi-Fi dimmer module.
