Hi @VicLing, welcome to the Sonos Community!
I’m sorry to hear that you’re having issues getting Sonos working with your Ring Doorbell. Since it’s something outside of the Sonos app and not directly connected, we don’t have any troubleshooting articles for Ring Doorbells working with Sonos, but after having a look around the community I found the following thread:
From what GuitarSuperstar said, It looks like the Sonos One speakers show in the app as speakers rather than echo devices, which is why they don’t show in the announcement device list. However, you should be able to use any of your Alexa integrated speakers if you use an Alexa Routine.
I don’t have the necessary products to test this, but my reply will bring this thread to the top of recently active where another community user who does have a similar setup can assist.
I hope this information helps!
