Hi Rob,
Thanks for sharing. The update from yesterday allows an ASH-21 to work, and I had hoped it would allow the doorbell to work too, although we have not tested a doorbell yet -- so this is helpful.
The size for the auto-detected doorbell you saw is wrong because it wasn't able to connect to the doorbell, so you can ignore it -- it would have changed to the correct size after a successful connection.
Could you use "Report Bug" from the home settings and check the checkbox to include logs and settings so I can get a look at what happened on the attempt to contact the doorbell?
I'll also follow up with you in email to ask about the difference in RTSP urls since I can't see the second one fully in the image you sent.
