Hey now thats what I call a good thunder and lightning show, went on for hours right through the night, Satellite dissapeared at about 5pm! so I new we were in for a good one, unplugged the TV and aerials just in case, and put on a DVD, still no Joy we lost the electricity supply, so watched the storm for a bit and had an early night, checked the rain guage this morning 30mm overnight, all water butts filled so a result there swimming pool overflowing

Only one casualty all the infra red sensor lights now are on permanently, so its of to Bauhaus for some replacements

Power off and on again about 5 seconds later.  Some will then light up for the duration of the setting you have chosen - so if your lights come on for half an hour once activated you have to wait 30 minutes to find out that 5 seconds was not enough... or too much.  You may need to experiment.  It may be a long night!!!
