Only Ring

Is it ok to only use Ring and not bell. Just to connect a transformer to the Ring.

Do I need a resitanse there?

Hey @RAW1, you can connect your Ring doorbell directly to your transformer. Please note a wire wound resistor is required when wiring your Doorbell directly to a transformer. You can find out more information in our Ring Help Center Article here for a Ring Video Doorbell and here for a Ring Video Doorbell 2.
