Leviton ZW15R inclusion fails, prompts to check log

I am trying to get a Leviton ZW15R to include (using official Z-Wave JS
add-on 0.5.0), but am running into issues. The first 20 or so times I tried, the device would time out of inclusion with no indication from ZWaveJS that any device was found.

I thought it might be a signal strength/interference issue, even though my HUSBZB is just on the other side of the wall, so I moved my RPi running HA into the same room (can’t easily move device as it is hardwired to 120V). That still didn’t work, so I put a longer USB extension to get the ZWave stick about 3 feet away from the receptacle. (As a quick sidenote about the signal and distance from the hub: the same room also has multiple other ZWave devices, including a device which is a repeater, and those have no connection issues. It seems like the inclusion process isn’t using the repeaters to help it find new devices.)

Finally, it gave me a message that inclusion failed (without first showing any inclusion progress), and to check the log for details. Unfortunately, every time I go to check the log, it seems to reset to only showing logs starting from when I opened the log page. So I left a log window open and after about 10 more failed attempts (with the stick 3 feet away) got the following:

Node 10 is my Honeywell T6 thermostat. I don’t see these messages about timed out while waiting for response or dropping message with invalid payload at any other time, but perhaps this happened because I temporarily moved my hub?
Is there anything of value in these logs, or do I need to try again with higher verbosity?
I don’t tend to have too many ZWave inclusion issues, so this has been very frustrating, and I don’t have much free time left to mess with this. Anyone else have issues with this device? Other ideas as to what could be wrong?

Those are probably due to moving the hub and the T6 no longer has a good signal path.

Try factory resetting the Leviton switch, then try including it.

Tried that a few times, still not working… :confused:
