Sorry, it's the C-5. Which driver are you referring to? The driver code section is empty, and there isn't anything in the device settings that says driver.
I found this article: Frustrated w/ Device Discovery So Far - #3 by mike.maxwell
There's a comment that says:
Yes, having it near WiFi will cause issues. Move it across the room or in another room where no 2.4ghz devices are within 3-6 feet.
I had the device sitting right next to my router, which is dual band 2.4Ghz and 5Ghz. I moved the hub out of the closet, closer, and completely unobstructed and it seems to be working much better now.
I know these things act as repeaters, but how close does the hub have to be to the first device, and how far away can each device be? I'm planning to move to a larger home in a few months and plan to have almost all the light switches replaced with GE Z-Wave dimmers/switches. Is range going to be a problem?
