So I was playing around with 2 new TP-Link HS110 units I bought from Amazon, and I was attempting to swap the two with two other existing units (which had older firmware), having the two new units take the identity (name/ID and pfSense dhcpd statically defined IP addresses) of the “older” units… Review of that device aside, I was pulling my hair out because the old units kept getting their old IPs, as did the new units!
Funnily enough, the units appear to “take turns” “phoning home” – such that in the Kasa control application, there were duplicates of the old unit name/IDs shown, and it “flip-flopped” on showing the availability (and also the recorded energy consumption).
I figured it must be the DHCP service/daemon, since I kept seeing the DHCPDISCOVER and DHCPOFFER in the dhcpd logs.
Time to roll up my sleeves and fix this…
