Our good friends invited us around last week to allow us to admire their new high tech lounge which has multiple 'mood' setting lighting and curtains that open and shut at the press of a button or from the iPad. I did suggest they just sent me the codes and I could play with the curtains without bothering to drive over....anyway I good bottle of wine was involved so it was worth the trip.
There is some sense in this madness as they can get all this working as if they were at home when Mr Burglar looks in when they are on holiday
So Womble, therein lies the answer, a computer controlled loo seat and flush, or controlled by a sensor on your ingress and egress.
Alternatively, I found last time I replaced my loo seat B&Q do about 12 types with slightly different fittings, different offset of the hinge and bolts to where the seat flips are needed for different loos so I suspect you have the wrong seat for your bowl & cistern.
