Can I connect a ring chime pro to my existing doorbell?

It’s a lovely Edwardian bell system with a flicking star indicating front door bell.

Hi @Vajrin. The Ring Chime Pro is designed to be used in conjunction with our Ring Video Doorbells or other Ring devices. If you have an existing Doorbell, you would have to replace it with a Ring Video Doorbell to use a Chime Pro. This Help Center article here has more information on the Chime Pro.
