IPv6 Address change trigger/event

1

Hi,
is there a means to get notified about IPv6 address changes of my ha-instance and than update a private DDNS server via URL-call (e.g. curl …)?
So far I haven’t detected any event/trigger.
Regards
Fred

Use an API call for an external website, like MyIP

A rest sensor in HA should do it.

Thanks for the hint.
So, I tried sensor.local_ip. Unfortunately, that only provides the IPv4 address.

I’m aming for the IPv6 address change. So far I haven’t found any entity providing the value.

You did look at System monitor - Home Assistant ?

I know it is limited in functionality, because it can only list one IPv6 address per interface, where a simple interface with no routing will have at least 2 addresses, if not 3 or 4.
If there is a router and maybe a DHCP service then this can go even higher.
HA is just lacking IPv6 functionality and even basic ones at that.

Thanks a lot!

System monitor ist the solution. The “System Monitor IPv6-Adresse end0” entity provides the ipv6 global address. Now I can use curl to call my own DDNS service.

Nevertheless, I agree: more/smoother(?) IPv6 functionallity in HA would be great.
