Of course, a true pedant would point out that the 3rd decade of the 21st century doesn't start until a year from tomorrow.

But according to Barbara Walters..   "This is 20/20"


and according to Google UPnP should be disabled as it is a security risk and your script is worthless.  Having received an email from Wyze about their database being hacked I was curious if our house cameras would show up when the script was run. They didn't and neither did the Honeywell Thermostat.

I made a slight change FindByType("ssdp:all", 0) rather than FindByType("upnp:rootdevice", 0) and it appeared to duplicate 1 or 2 times the root devices. So, I further looked at the HasChildren property - my Router does, my Roku devices don't. Any suggestions how I might find out about the children

Other than the usual paranoia about IoT devices and a predilection to avoid them when possible and neuter them when it is not, I am not all that familiar with MSFT's take on the implementation of a UPnP query protocol.   About the only thing I can suggest is a look at the API documentation if you haven't already.

I believe I addressed the concerns/paranoia in an earlier post. I think if the Object has children and the children or services is System.__ComObject then the children are a COM array but you have to invoke another function FindByUDN()... and that is pointless. Finding the root devices is enough. Since my Wyze cameras are PlugnPlay but not recognized I feel a little better - even though my email and router type were part of the recent hack.

Not sure what previous post you are referring to.  I probably missed the obvious someplace along the way.  I guess my paranoia with regards to IoT is mostly related to things other than hacking although hacking is a legitimate concern.
