Sorry for resurrecting this old(ish) thread, but I’m stumbling into a very similar issue…
I’ve just finished moving some devices from one subnet to another and the recently moved devices aren’t being recognised by HA.
To elaborate: I have several other devices which I moved a few weeks ago, all on the same Wifi SSID, same subnet, etc - and they are being recognised by HA, so it can’t be an mDNS issue… (maybe 
)
The ESPHome GUI can see them, I can update their configuration, show logs, etc, but HA can’t see them…
Looking at packet captures, it appears that “HA” (running on a PI, so this could be ESPHome too…) is ARPing for the old IP address, so IMO something is stuck with the old address…
I’ve restarted HA, rebooted the entire device, etc, but I’m still seeing the old addresses in the logs:

I’m seeing no attempts to reach those old addresses on :6053, just ARPs (which makes sense).
So, in my mind, I think that “ESPHome” is working, but “HA” is still using the old addresses…???

I’ve tried using use_address with the same address as static_ip, but that made no change.
I tried removing the manual_ip section, and returning to DHCP (which has a static mapping to the same address) - thinking that might need to update something, but still no change.
Nothing obvious in HA’s /config folder as I grep’d for the old addresses (grep -lir "192.168.7." /config/*)
Any more ideas / pointers?
