Ring Error Code P1-101: What Is This Power Issue and How Do I Fix It?

Problem Description

Ring error P1-101 indicates power-related problem. Device not receiving adequate power from battery or transformer.

Why This Happens in Real Homes

P1-101 is a power error that means the doorbell is not getting enough voltage from the transformer or the battery is critically low. For hardwired doorbells, this almost always means the transformer is undersized — you need at least 16V 30VA for Ring doorbells and 24V 40VA for the Pro models. For battery doorbells, it means the battery dropped below the minimum operating threshold. Charge the battery fully before troubleshooting anything else. A half-dead battery causes all sorts of erratic behavior including failed WiFi connections and missed recordings that people blame on software when it is really just low power.
