Continuous invalid logins from mobile phone provider. how to check own device?

as of late, I receive constant invalid logins from my mobile phone provider. At least, when I enter the ip address in a whois engine, the address of Vodafone is displayed.

Since I am not sure this is my own device (iPhone) I am hesitant to allow it as trusted source…
Can we find out somehow if the ip address is in fact ones own mobile device?

disconnect from wifi
open browser on phone and enter whatsmyip

it should show u what ip your phone uses (note this can change, so adding this to trusted source is bad idea)

thanks. the ip address first triplet with the same 2 digits, but the other 3 are different. So apparently something else is going on. How could I proceed in finding out the origin of the login (could it come from some internal service?).
Or stop my HA instance from being frustrated by this?

as i said it could have changed and you will probably get a new address everytime you switch from wifi as they are DHCP leased from your phone provider

As a test try connecting to HA from your phone if you do that and see if you get another invalid login (disconnected from wifi of course)

They are CGNAT maybe?

Once you have logged in on the device on WiFi even when you switch to 4G it shouldn’t ask you to re-auth anyway…

I wouldn’t know… how can I tell.

I don’t see any re-auth or even auth requests at all. Its simply that my automation gets triggered and displays a persistent notification.

What automation? Are you using the authenticated sensor?

my bad here, thought the notifications to be caused by one of my service-automations but it is not active. I am not using the authenticated sensor.

so the notifications must be sent by HA itself…

What is this? I can’t find any reference to it in the docs?

Custom Component… It’s in HACS and is written by Ludeeus as well… It’s pretty cool.
