How to discover devices on a Zero Tier interface

Hi there.

I would like to configure HA in order to discover devices on the Zero Tier interface.
I haven’t been able to figure it out. I have used Zero Tier for years on various types of computers.

The objective is to discover and use/control devices on a remote location.

Details: HA in Pi5, Zero Tier add-on installed, HA visible on the zerotier address.

On another Raspberry Pi with no HA install, I have eth0, wlan0 (wifi) and ztyxawec6u (zerotier). However, on the Pi HA instance, I poked through HA configs and can only see the Ethernet interface and the Wifi one.

More details about the setup: HA with Zero Tier on location 1 (LAN), wanted to control devices on a remote location 2.

Any idea what to do?

Many thanks.
