That’s a brand-new product, it’s been out less than a month. Intended for professional installers. It’s a spectrum analyzer plus the zensys mapping tools Plus a kind of packet sniffer for a Z wave network. It’s part of the strategy that involved publishing the API, because they want to be considered by local installers.
I don’t think you’d really need it. It’s really rare to get local interference with a Z wave network, so the spectrum analyzer (which is a big part of the cost) is really just a peace of mind tool for people who are used to using one for other protocols.
As far as the mapping tools, you could just get a $49 AEON USB stick and then use the free zensys tools that work with that.
As to whether you could understand the reports, that’s hard to say. I thought they were pretty clear, but there have been people who have posted in the forum who had no idea what they were looking at.
