You can control non dimmable lighting with Lightwave, however, this may require a solution other than the installation of a smart dimmer.
Dimmers always require dimmable lamps
Like all standard electronic dimmers, Lightwave dimmers and plug-in dimmers need dimmable LED, halogen or incandescent lamps (bulbs) to work properly. They should not be used with non-dimmable lamps. Non-dimmable lamps include CFLs (energy saving bulbs or tube lights), certain brands of LED and LED strip lights.
Using non-dimmable lamps such as non-dimmable LEDs will usually cause the dimmers to flicker, or to behave erratically if they are not dimmable. Even if the lamp appears stable initially, it could damage to the dimmer over a longer period. For a list of compatible LED lamps, please check our compatibility charts.
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.
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.
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.
Lightwave relays are designed to switch power or lighting circuits. They can be used to remotely control lighting circuits with loads that are too high for a Lightwave dimmer, or circuits that power non dimmable lamps or LED strip.
The LW821 In-line Relay can also be used to switch low voltage lighting. A relay needs to be installed in the lighting circuit wherever there is access to the live and neutral wires. They are designed to fit into small spaces such as a ceiling void, so usually this is relatively easy to do. Once the relay is installed, a wire-free switch can be linked to it and communicate wirelessly when pressed. These versatile switches look like dimmers, but can be positioned anywhere with sticky pads or screwed to a back box. You can also use a Mood controller in the same way.
