So the migration to my new C8 went pretty well - I had some minor issues with Hub Mesh device links on my secondary C7 (pointing to the C8) break and I had to manually remove them after re-linking the devices. And of course, my troublesome Zen Thermostats (Zigbee) needed to be re-paired before they'd function on the C8.
However, the one thing I can't resolve is a mysterious Zwave ghost that was not present on my C7 prior to the migration. Is there any way to work out what this is from, and if it's just an existing device that just needs to be excluded and re-included?
Power up the old hub and see if that node is there, and what device it was linked to.
Maybe a device got lost from the hub DB during the migration somehow?
