However, it will probably do the same as my other two and sit in a drawer unused for most of it’s life
Really? Shame.
I’ve just counted up and I’ve got 7 running over two houses. They mostly monitor room and water temperatures, switch lights on and off (according to sunset times), [google print]er sharing, upload PV production data and control the heating. Just started playing with monitoring human presence using wifi and bluetooth scanning which may, in turn, affect the lighting and heating.
Not sure I can see any advantage in the new version for me as my uses are fairly low-demand, and the most useful Pi for me so far is the Zero W – but it would certainly be good for some people.
