2 Ring Doorbells on One Transformer and How to Do This?
Some homeowners ask if it’s possible to run many Ring doorbells off of a single transformer as the demand for improved surveillance rises.
To do so, confirm that the transformer’s power matches the needs of both doorbells. Additionally, if supported, connect doorbells in parallel or series to the transformer’s terminals.
Read the full article to learn in detail how to connect two ring doorbells on one transformer.

What Type of Transformer Is Important to Power Two Ring Doorbells?
You will require a compatible low-voltage transformer to efficiently power two Ring doorbells. Here is a more thorough breakdown of the transformer specifications:
Voltage Output:
A voltage output of 16 to 24 volts AC is commonly necessary to Ring doorbells. For the doorbells to operate as well as possible, it counts to select a transformer that delivers the right voltage.
The devices may have operating problems or damage if a transformer is present whose voltage output is outside of this range.
Power Capacity:
The highest amount of power the transformer is capable of supplying is indicated by its power capacity, which appears in Volt-Amps (VA). And users need a transformer with a power of at least 30VA or more to operate two Ring doorbells at once.
Make sure the transformer’s capacity meets or exceeds the whole power needs of the two doorbells since each Ring doorbell model specifies its power requirements.
Compatibility and Wiring:
It is important to confirm that the transformer complies with local electrical rules and is compatible with the electrical system in your home.
Inspect to see if the transformer can handle the wire configuration needed to power two doorbells.
Make sure the transformer supports your preferred wiring layout because you may need to wire the doorbells in parallel or in series depending on the transformer’s design.
Ring Doorbell Models:
Power requirements for different Ring doorbell models could differ slightly.
Users always need to remember that consulting the manufacturer’s specs and guidance for each model determines specific transformer requirements.

Similar to the first Ring doorbell, attach the second one nearby and check that it receives enough power.
5. Test both doorbells and modify preferences and settings
Restart the power source and check both Ring doorbells to make sure they are operating properly. Verify the operation of the live view, notifications, and chime Giga Secure.
Then, use the Ring app to adjust the settings and preferences for both doorbells, including chime settings, motion detection, and notification options.
