I setup a new C-8 Pro today (migration from my C-8), but did not migrate any Z-Wave. The old hub did not have any Z-Wave devices to begin with. Platform version 2.3.9.143. All of my Zigbee devices migrated and are working fine. I am unable to pair any Z-Wave device. I have tried Aeotec Range Extend…

If you haven't tried this already, try completely rebooting the Z-Wave radio by: Shutting down the hub from Settings > Shut Down. Unplugging the hub from wall power after the LED turns red. Wait at least 30 seconds, then plug the hub back into power to restart.

If the shut down dance does not work then next thing I would try is a Z-Wave radio reset. Use the diagnostic tool in the Advanced menu to reset the radio. Hubitat Diagnostic Tool How to use the Hubitat Diagnostic Tool to troubleshoot an unresponsive hub, perform a soft reset, downgrad…

I have tried all of that. Hub power cycle, radio reset from the diagnostics tool, disabling and enabling the radio. Nothing seems to work.

How are you powering the hub -- see second part of Jeff's post directly above...

With a POE adapter. I can try USBC PSU directly. https://a.co/d/fSTy4Hg

[image] breazile: With a POE adapter And we have a winner.... That is your problem with both hubs. Also, do not use a USB-C block and C to C cord. That often does not work because the port on the hub does not negotiate for power. You will want to use a USB-A block and A to C cord (like what…

If the uav power doest resolve your issue, I would check the antenna as on of mine was broken cause issues. A good test would be to try and pair a zwave unit <10cm from the hub as when my unit was having pairing issues and before I had found the antenna broken it would achieve successful pairing. P…

Had nothing to do with the power. It turns out that the LiftMaster gateway was interfering. I moved it away and things started working again. [IMG_7354]

There are known issues with PoE power so if you have any other zwave problems try a normal supply. There have also been certain PoE splitters that work fine so maybe you have one of the good ones.

Understood. I tried the in box PSU, and still had problems, so I started looking at other things. This particular splitter seems to be ok. I compared it to the inbox PSU with a power meter just in case it was on the margin. Also made sure my PoE port could supply more than 12w. [IMG_7353]

Cannot add any Z-Wave to a new C-8 Pro

There's a wonderful post with information about the POE issue here. The reason for the problems with some POE supplies is laid out quite expertly. Worth a few moments of your time...
