Use Alarm base unit as a chime for Doorbell?

Hi @Teddan. At this time, the Ring Alarm Base Station cannot be used to play chimes from Ring Doorbells or Cameras. This functionality has been requested before, which you can find on our Feature Request board. Feel free to add your vote and feedback to that request. While Ring isn’t compatible with Google hub, we are compatible with Alexa. You can learn more about receiving Ring Doorbell notifications via Alexa here. I hope this information helps!
