WireGuard on UDM Pro: WireGuard Hostname?

Hardware
1

I use the WireGuard Add-On. I also have template sensors in my HA config that track which clients are connected to WireGuard and amount of data transferred/received. Here is a snippet:

  - platform: rest
    name: wireguard
    resource: http://xxxxxxxx-wireguard #hostname from add-on home screen
    json_attributes:
        - iphone
    value_template: "OK"

  - platform: template
    sensors:
        wireguard_iphone_status:
            friendly_name: "Wireguard iPhone Status"
            value_template: >-
                {% if state_attr('sensor.wireguard', 'iphone').latest_handshake > ( as_timestamp(now()) ) -180 %}
                    Connected
                {% else %}
                    Disconnected
                {% endif %}

It would be nice to be able to run WireGuard from my UDMP so I could VPN into the house even if the HA server is rebooting etc. But I presume it could mean that I’d no longer be able to use the sensors in my config because they require I enter the WireGuard hostname in the resource field of the REST sensor.

Is anyone UDMP savvy such that they could tell me whether I’d have a way to know the hostname of the WireGuard instance running in UDMP? Perhaps via SSH?
