A Guide to Wireless Range & Repeaters

One more thought. While I understand the marketing reasons for the decision, the fact that SmartThings gives customers zero guidance on how to set up a network backbone does lead to a lot of frustration that shouldn’t have to exist. if people knew that .1) The hub should be located centrally in the home, both vertically and horizontally. Don’t put it in a garage or basement as those have concrete and pipes and metal objects which will reduce signal. If your Internet router is off in some inaccessible corner, you can use a Wi-Fi access point that has a ethernet port on the side and plug into that. Also, the hub should not be put in a cabinet. You just want to make it as easy as possible for signal to spread around your house. .2) you need one device that can repeat about every 40 feet…

FAQ: Create an all-around z-wave presence in a 4,000 sq ft home?

Is there a way to create an all-around “z-wave presence” in my 4000 sq ft home? My home is not just a two story block home. It is a one story, spread out “ranch style”, so it really covers 4,000 sq ft on horizontal terrain. What I want to do is create a z-wave mesh that is available anywhere in my home, similar to my WiFi system. (In the WiFi case, I simply distributed Unifi AP-Pro’s throughout the home so that all spaces are covered.) So . . . how can I do something similar with Z-wave? I don’t want to worry about NOT having a Z-Wave signal available. I just want it to be there when/if I need it. Any suggestions and/or words of wisdom?
