101 ways to use LightwaveRF

No. 9 Scene control

Scene control provides a very convenient way to set the level of all of your room lights at once and recall it as a favourite saved setup. With the press of a single button on a LightwaveRF Mood Remote or Controller, Scene Setter, or the App, you can dim selected lights and lamps to provide the perfect atmosphere for watching a movie or to create a relaxed mood for entertaining guests. You can even include power sockets into the scene.

Traditionally, scene lighting has been complex, expensive and hardwired. LightwaveRF is different. It’s wireless, much simpler to install and setup, and more affordable! New modules can be added at any time, and adjustments to preset scenes can be made in seconds. Any LightwaveRF dimmers, power sockets or plug-in sockets can be included into a scene.

No. 10 Simulated Occupancy

Using the LightwaveRF app to set a random timer event, you can ensure that your lights will turn on and off at random times whilst you are away, during the evening or on holiday. This provides added security by giving the illusion that you are at home when you are not.

The random timer is better than a set timer, as the illusion is more complete. With a Lightwave Link and the LightwaveRF app, you can achieve simulated occupancy with as little as a lamp plugged into a plug-in dimmer.

No. 16 Remotely manage my holiday home

LightwaveRF is very useful for monitoring and managing a second home, holiday home or static caravan. The energy monitor will allow you to keep an eye on power consumption; plugin sockets or dimmers can put on lights on a timer for security; Radiator Valves and Boiler control can make sure that the heating is under control and warm the house before you or your guests arrive; and relays or power sockets can manage gates, curtains or switch off anything that may have been left on.

No. 11 From dusk till dawn

Using the LightwaveRF App and Link, you can set lights or lamps to automatically come on at dusk or dawn everyday. The dusk and dawn timer automatically adjusts to cope with the changing light, making it much more sophisticated than a standard timer.

Any LightwaveRF lighting or power device, such as a dimmer, plug-in or in-line relay, can be timed in this way. It’s a very cost effective way to provide this intelligent solution throughout the home.

No. 7 One switch to rule them all…

A simple yet much underestimated piece of kit is the LightwaveRF Wire-free Switch. You can use this device to trigger any number of Lightwave devices at once. You can also do this with the Scene Selector (Mood Lighting Controller), the Mood Remote, or ,of course, from the LightwaveRF Apps.

At the press of one button, you can trigger dimmers and plugin sockets to turn on all of your lounge lamps, or perhaps turn off all of your sockets and standbys when you leave.

No. 20 Blind control

You can use a LightwaveRF LW821 In-line relay to operate many types of curtain or blind motors. This allows them to be opened and closed using the App and/or a wireless On/Off/Stop switch. You can also go one step further and set a timer that will automatically open or close the curtains or blinds at dawn or dusk. So you can now be woken up naturally every day, as the bright sunlight streams into your bedroom*. Which is a good thing. Obviously.

*Please note offer of bright sunlight is not always applicable to UK based customers.
