About this product


  • Fully remote controllable two gang dimmer switch
  • Works as part of the LightwaveRF smart home range
  • Control via your smartphone or tablet

Product overview

• Fully remote controllable two gang dimmer switch to replace standard double light switches
• Works as part of the LightwaveRF home automation range
• Control via your smartphone or tablet when you are out of the house or on holiday
• Master switch

How does this light switch work?
The LightwaveRF double gang light switch allows you to replace your standard light switch with LightwaveRF technology. You can control this from one of the handheld remotes from the range or even use your smartphone, tablet or computer to turn the socket on and off. This can prove invaluable for security purposes when you are out of the house to deter burglars.

How easy is the switch to install?
If you have a working knowledge of household electrics you should be able to install the socket yourself. It is installed in the same way, straight into a standard 25mm or 35mm back box, and uses the current household wiring without the need to re-wire your home. If you are unsure about connecting the dimmer switch to the mains, we recommend you consult a qualified electrician.

Please note: To use the app with this product, you will require the optional LightwaveRF Wi-Fi Link A23RX.

Hi, You spec this as OK for a 25mm back box. I think this is a mistake? The product has a depth of 30mm.

Asked by: PJ33

I have a light switch on floor one and a light switch on floor 2 both are wired to a two gang two way switch. This is a mater switch do I need a slave?

Asked by: Manoj
One on your system will be master and one will be a slave but I do not know what the one you will replace will be as it depends on how the house has been wired.

Do you need any extra Home Hub for this to work or does it just connect straight to your home wifi?

Asked by: bobobobob
You would also need the wifi link hub in order for this to work.

Does this switch have the necessary connections and instructions to allow it to be used as a replacement where there are tow switches that control one light - e.g. switches at the top and bottom and bottom of the stairs?
