HomeBase 2 Wifi MAC address

How do I find out the MAC address of the wifi interface on the HomeBase 2? There is only 1 MAC address printed on the bottom of the device, and that appears to be the MAC address for the Ethernet interface.

If I check the app it lists the same MAC address, but this is not the MAC address my router lists, however my router warns me that “Mac Randomisation” is enabled for the device

You need to set it up and get it to try connecting, to get the MAC
(disable whitelisting if you have it on, let it connect, spot the new one, then add it and re-enable whitelisting)

The first 6 digits of mine are all the same barring the 2nd digit.
