I have the aeotec zwave HEM that I imagine you are talking about, and have been using it for 4 years. Mine is on its own zwave modem, separate from the one I use for everything else, but you can also try increasing the reporting intervals, and maybe disabling reporting for anything you don't care about.
Yes this is the one I have.
Yes. It generates a lot of traffic. Once you get it reporting reliably, I struggle to see the benefit of a more expensive solution unless you want more channels.
Channels would be nice. Its just annoying at this point to have to keep resetting it. Makes the logs useless.
I haven't had to reset mine in 4 years. I would get another radio and move it to its own network.
