Why can't you make an on/off switch?

It may seem an obvious solution, but it is very difficult to make a standard on/off switch that can be controlled by wireless communication – at least in the UK.

UK lighting circuits usually lack the presence of a neutral wire at the switch location; they only have a live wire. This is fine for a normal switch which interrupts this wire to cut the power; however, a wireless switch needs a tiny constant current to power its radio communication module. Once the live wire is cut, without a neutral wire to create a separate circuit this power is lost and the switch looses communication. A dimmer avoids this problem by always allowing a very tiny trickle of current through the live wire to create a circuit. This isn’t enough to illuminate a connected lamp, but is enough to power the wireless RF module.

 

 

SMART SERIES

 

Wire the non-dimmable lighting source directly to one of our relays and not to the dimmer. You can then programme a spare channel of the dimmer to become a wireless switch for the relay (MAGIC SWITCH)

This wireless switching setup can be used with Lightwave relays for non dimmable lamps and even our smart plug sockets which may have a table lamp plugged into it.

The Image above is based on a retro wiring system where no neutral wire is available. As no neutral wire is available the Primary channel must be hard wired to a dimmable lighting circuit and channel 2 will automatically get power meaning it can be programmed to be a wireless wall switch for any other lightwave devices such as relays and sockets.

 

STEP 1:  Please ensure that both dimmer and relay have been added to the app and name them accordingly

 

STEP 2:  In the app select ADD Automation and SELECT GROUP

 

STEP 3:  Please select SWITCH in GROUP AUTOMATION

 

STEP 4:  You will see a list of rooms, please select the relay/socket and dimmer channel you would like to be grouped together

 

STEP 5:  Save the automation and give it a name such as relay and dimmer group

 

Now the automation has been set up you will be able to wirelessly control the relay/socket from any spare channel of a dimmer.

 

Please note:

A Group switch automation can be applied to as many devices as you wish meaning you can programme a spare dimmer channel to control multiple relays/sockets simultaneously for ON and OFF functionality.

 

The group automation means all devices that are linked together will always turn on and off at the same time when the relay/socket or the dimmer channel is triggered manually or from the app

 

The link plus hub will always remember that certain devices have been wirelessly grouped via an automation and will still work even if the internet connection drops in your house. As long as the Lightwave link plus hub has power all automations will still run

Use a relay and Wire-free switch to control non-dimmable lamps

You can still use Lightwave to control non dimmable lighting, but you need to take a slightly different approach by using a relay and wire-free switch instead of a dimmer.
