Success!
At the recommendation of another troubleshooting thread (Troubleshooting Aeon Labs Home Energy Meter v1), I performed a Z-Wave exclusion and re-pair. One of my (now many) device handlers was picked by default afterwards and appears to be reporting in lock step with my turning a lamp on and off.
Prior to that, I also removed the device from the API and repaired, without success. My LED is now solid. I can’t explain why it was going off before the removal/exclusions.
I have one parting question: Do the K/L markings on the clamps have any implications for the dual clamp users? In my limited testing, I have clamps oriented both ways on the same wire and they are reporting within 1 watt of each other. See these links for what I am referring to:

Thanks for everyone’s help.
