So maybe you guys have already thought of this. It probably wouldn’t be the highest-selling/most exciting product you would have in your lineup. But, how about a handheld Z-Wave signal strength meter? It doesn’t have to be complicated like this Z-wave tool box. I’m thinking very simple, much like the functionality that your current light switches have (Green, Yellow & Red indication). The advantage is that you wouldn’t have to install the switch before you know the signal strength. It could be helpful during mesh planning & debug.
i have not had issues with my signal strength but my home is not overly large. Pretty cool idea.
