Thanks, Brian. I just ordered all new GE devices from RS, and from what I've read, they are beaming devices.For the most part, yes. I think there may be some older wall switches that don't do the "beaming" to neighboring devices (which facilitates the mesh network). The GE ones I've gotten worked fine. With Z-Wave, the rule is basically anything that is not working off of batteries will beam signals from neighboring devices and allow you to extend your network.
Thanks. I look forward to the numbers.The GE manual that came with the items I purchased showed a line-of-sight distance of 100', and also listed other ranges based on the number of walls between devices as well as construction materials (sheetrock vs. concrete, and plastic gang boxes vs. metal).
I will edit this post with the numbers when I get a chance.
