I bought the Procet 100Mb PTC-AF-5V from Amazon, but it didn't work for me. My POE source is a TP-Link TL-SG108PE switch and the hub is a C-8 Pro.
My Z-Wave network started going haywire, with the main symptom being that old non-Plus devices were not responding or very slow to respond. Newer devices (Z-Wave Plus) seemed to mostly be working, but if I sent a command to an older device first, nothing would respond for a while. Multiple Z-Wave network repairs showed failed nodes.
I just plugged the hub back into the supplied power brick and did a repair and everything is back to normal. It looks like this splitter either has enough variance in samples to not always work, or doesn't work with this TP-Link switch.
