Funnily enough, that is exactly what I said to Clive! In fact his original
solution consisted of a timer relay
to just do the house lights and I thought that would be fine. However, when he
started talking about
controlling 'daylight', I accepted that a bit of intelligence would make things
easier and certainly more
flexible to allow additions to the functionality in the future.

I also thought of Arduino, but I have no experience with it, whereas I have
played around with the Pi.

The nice thing about the Pi is that even now, everything has been done before
and we can buy the
hardware quite cheaply from CPC / element 14
