ESPresence. Error with IP addresses

Not sure if this is correct place… other posts on this topic are in Config or ESPHome chats…
But here goes…
Have some ESP32-C3 minis (4Mb ram) onto one of which I have loaded ESPresence. I can connect to it using the IP address my router says they are on (192.168.1.155) but ESPresence>Nodes> says it is on a different one (192.168.1.148).
Could this be why I cannot get any further in setting up the Bluetooth tracking feature?
Happy to share any other details required to facilitate, :face_with_peeking_eye::no_mouth:

[edit: ip address error self corrected!]

Well, before you all jump in and before I go to bed, having spent most of Saturday fighting with this…

We are a bit further on…
Now, 6 nodes set up and recognised in ESPresence although they all seem to be duplicated (which I may have just solved!)

I managed to find the irk numbers of my iPhone watch and iPad and these seem to show up in the list of devices.

I think I need to work on the distance settings and would be great to get the map function working…
I copied the example text exactly from GitHub… the nodes appear to be correctly placed, but there are no walls!!:face_with_peeking_eye:

Anyway, I am a bit further on than I was this morning…. Let’s see what Sunday brings!!
