Where are the urn devices listed?

Hi all; I’m new here so greetings!

I was trying to figure out (and I hope I’m describing this clearly …) where are the urn devices listed? I mean, when I added my SmartSwitch I did some trial and error to find it was defined as “urn:upnp-org:serviceId:SwitchPower1” . I could see the ID number in; /devices/lights/advanced so that was obvious. But where do I find what Verde calls an added device? If I include a lock, is it :“urn:upnp-org:serviceId:Lock1”?

Also, any way to stop the log file from always scrolling to the bottom of the screen?

For the built-in stuff, there’s a list of the :serviceId: stuff here:

The technical meaning of each of these, along with examples, are often scattered across other Wiki pages, on the UPnP site, etc…
