For an operation of that size, I would definitely get the Z wave Products toolbox. This is a small device that a professional installer can take with them from one location to another that can map the Z wave network and has a bunch of diagnostic tools. It lists at $250, but is often on sale for about $150. Since smartthings does not provide users with anyway to map their own Z wave networks, you have to add third-party products to get those capabilities. And this is a good one. 
(Fair warning: it’s not intended for end-users and it’s not particularly consumer friendly as far as explaining what everything is and labeling all the charts and that sort of thing. But for a pro installer or field tech, it has a lot of information. )
