Can't add Zooz ZEN51 or ZEN52 devices

I wonder if it has something to do with POE.

Yes, there are known and documented issues with PoE splitters causing problems specifically with Z-wave on the C8. Now I feel bad I did not think of this before and you could have avoided re-pairing all your devices. To be fair it is in the READ FIRST post.

Did you recently change the power source to PoE? All of your other posts read as if everything as working fine until recently, this is why I did not really think of the PoE issue as being a potential cause,

Z-Wave Issues

For partial or total loss of Z-Wave control (radio seems dead), before doing anything else please shut down the hub from settings and unplug for 30 seconds, then re-plug to boot back up. This will allow the radios to fully power down and restart. A regular reboot only restarts the platform and not the radio hardware.

...

• How is Hub being powered? Supplied power block or other (explain)
  • PoE power (with splitter) is known to cause major Z-Wave issues on the C-8 hub.
  • See this post for detailed write up on PoE testing: PoE and the C8 (with extensive testing)
• Provide screenshots showing entire Z-Wave details Page
• Provide screenshot of Z-Wave Topology Map (red/blue squares)

Also, I have two BE469ZP and they work without issues, so that lock should not be the cause of all your issues. However, I could see if you have a power source issue, the way the hub has to talk to lock could be more taxing on the radio and cause more issues when the lock is paired.
