I use a weatherproof box purchased from screwfix, to contain a 4 socket extension, to which I have plugged a wemo switch into. From this, I've plugged a water fountain in. The water fountain used to empty if it was left on all day, because of its design. Now I can wow guests by turning on the fountain from my phone whilst stood inside, looking through the patio doors. The plug is at the end of the garden, but I've put a apple express in the garden to boost the wifi for the wemo to work properly. I can set rules for the fountain to turn on & off as I come home & leave, through the iftt app, or just use the wemo app to turn the fountain on 3 hours after sunrise and turn off 2 hours after sunset.
