    Does anyone have any ideas where I can get a simple automatic switch that is sensitive to when the sun is shining?

    I have a d.i.y swimming pool with black pipe solar collector, It is hard for me to estimate what the days weather is gonna be like before I go off and work. A simple automatic switch that was sensitive to the sunshine would solve the problem by running the pump ony when its hot...

    I can buy more complicated systems that switch the pump on when the water in the collector is hot, however these cost £400 plus and I can't justify that price..

    many thanks
