101 ways to use LightwaveRF

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.
