About This Project
I have been tinkering about with the idea of home automation for a number of years i.e smart lighting and heating and more,
so using my pi with cayenne is for me a no brainer, but as we all know with all projects as one problem is resolved another ten pop up.
one problem for me is cramming as many components into a small enclosure generates heat and putting it in a bucket of water was not my best idea, (not recommended)
so with a second hand 12v dc cooling fan my project is now running 10 degrees cooler, happy days and happy electronics.
16ch relay board
2nd hand 12v fan
