For me it is my ertser Pi and thus set a good base to savor the possibilities. Serve on a permanent sol of Pi with me as home control server with FHEM and does his job in the area quite well so far. But I come also already a few ideas for what the acquisition of another Pi would be worth.
Only the case, I do not set a date because I've ordered, because of the comments in the reviews just another of OneNineDesign and am very happy with this.
Priced these sets are a good option as you would pay more in total for the items.
