already buy Wemo-enabled plugs, and now you can buy Wemo-enabled light switches. Once again it isn't cheap expect to pay around £39.99 for a light switch and the same for a plug socket that you can use to control table lamps - but the technology is interesting: you can combine Wemo with the “If This Then That” web service, so for example you could add a motion detector to switch on the hall light when you open the front door or get the light switch to activate at sunset each evening.
If you like the idea of motion sensors, light sensors or timers for your lighting but would rather not shell out for expensive smartphoneconnected kit, you don't have to: a simple but effective motion and sound-sensing light switch will set you back less than £10, an electronic timer light switch will cost less than £10 and one with a built-in sensor will only cost a few pounds more. The smartphone-compatible hardware may have the wow factor, but lower-tech options won't give your wallet the "ow" factor
