Lighting:
Some of the benefits of automating the lighting are if you preset every light
in the house to come on to 80% then an average saving of 40% on your lighting
bill is made, If you couple this with Hall, landing and corridors that only
activate when you pass through and then shut off when you leave further savings
are made. A light point sensor can further the savings by adjusting the light
levels automatically relative to the light outside.
