Be sure to check for Android devcies as well, they have MAC address randomizers now enabled by default.
Do a MAC address look up online to see if that help identify unknown devices.
Begin to power OFF devices one at a time to see if something appears for you...
What FW version is the system using?

I’ve disabled private wifi address on all my iOS devices thinking it was those.
Part of the challenge is they don’t age out quickly so I’m not sure if it’s a quirk with DHCP and devices initially using the LAA Mac but then settling on their static IP that has been assigned but leaving the DEV cached in the Orbi. If it’s this then it may eventually reconcile over time as leases are renewed and devices stick to their statics, but maybe it occurs at re lease if devices themselves are still set to dynamic and are relying on the Orbi to issue the static.
The DEV entries rarely respond to pings but I had a few that responded unreliably. Which suggests they are tombstone entries. The Orbi doesn’t have seem to have a neat way to clear individual ARP entries or do an entire flush without a reboot like you’d get with an enterprise device.
No Androids on network.
Google search says they are LAA self-assigned Macs starting 02.
I had a play with powering off iOS to see if they were from those devices, also turned off private addressing - they seem to be part of the issue as one entry was my Apple Watch that popped up, but other unknown devices pop up with DEV entries that I cannot identify.
7.2.6.31 running on the 860 mesh nodes.
I have powered off the extender and rebooted the router and so far no DEV entries are appearing. So I'm now wondering if it's caused by unanswered device DHCP requests via the extender leaving cached entries in the ARP table. The extender is an older RBS50Y reset into extender mode not Orbi mode - seems to work well apart from being the potential cause of rogue device entries.
I'll leave it off for a few days then power it back on and see if the rogues come back.
What mode is the RBS50Y working in? I presume extender mode?
Possible could have been some odd behavior there. Sounds like you narrowed it down.
Let us know after a few days if something appears.
- Yes the RBS50Y was setup in extender mode.
I have had no recurrence of the DEV entries since it’s been powered down for 4 days now. The DEV entries were appearing multiple times per day.
So I’ll leave the extender off for now.Might try the RBSY again to see if the DEV devices appear. If so, then you'll know.
