I wanted to wait at least a couple of weeks to see how the new antenna would work after I did the pivot. 19 days later the net result is that I'm still getting inferior performance than the C-7.
I installed the C-8 in early-mid April and my connections were “better” only 1 day since them. (By better I mean more devices were connecting faster than slower). I switched the original antennas as they thought one might be bad, but that didn’t help. I then bought a bigger antenna, one that is rectangular shaped and tried it with the flat side parallel to my house, and when that didn’t help, turned it 90 degrees, and that still hasn’t helped.
I created some macros in Excel and copy, paste, and massage the Z-Wave table every day, typically in the morning, to, hopefully, remove that as a variable. As I mentioned above, except for 1 day (when I was 1 net device faster than slower) every single day since installing the C-8 I’ve had more devices connecting slower then before then are now connecting faster then they were on the C-7.
I had 49 devices and on the last C-7 day, in 100, 40, 9.6 order I had:
100 = 39
40 = 4
9.6 = 7
Today, 19 days after they suggested I do the 90 degree pivot so the flat side of the antennas were perpendicular to the main home angle I’m at.
100 = 38
40 = 4
9.6 = 7
With 5 faster, 6, slower and 38 unchanged. This is one of my best days. I am often much worse than that. Below is the screenshot I made of graphs of the speeds and faster/slower/same. The first data point is where the C-7 was. As you’ll see, especially from the bottom graphs, except for that one day I’ve always had more devices being slower on the C-8 then were faster with it. (In the bottom 2 charts the orange is slower and the blue is faster). So, at least from my experience, the C-8 has been a big bust and waste of money as I’m getting inferior performance.
