Wiring 2nd Gen Google Nest Doorbell without Chime

[RishMaster]

What is the correct wiring guide to power the Google Nest Doorbell (wired) Gen 2 with a plug-in 24VAC 40VA transformer, with no wired chime?

Do I need to use the Google Chime and/or a 50W 25 Omh resistor? Or neither?

Hi @RishMaster,

Thank you for posting in the community. I understand you'd like to know if you can install a Nest Doorbell (2nd gen, wired) with a plug-in 24VAC 40VA transformer with no wired chime. I'm happy to assist you.

Could you please confirm if, when you say "installing your doorbell with no wired chime," you are referring to the chime connector included with the doorbell in the box, or the chime you have installed in your house?

If you're referring to the chime installed in your house, please confirm whether you have a mechanical, digital, or wireless chime.

If you're referring to the chime connector included with the doorbell in the box, the doorbell must be installed with this chime connector as part of the requirements. The chime connector allows the chime's wires to deliver constant power to the Nest Doorbell (wired, 2nd gen) and Nest Doorbell (wired) and protects your chime from damage. In addition, without the chime connector, you might experience chime buzzing or unexpected chimes.

In the meantime, you can learn more about this by visiting the article Check Nest Doorbell compatibility.

Please keep me posted.

Regards,

Anders

Hi Anders,

There is no mechanical chime in the house (which would normally provide some resistance).  I was planning on using Google Home Mini Smart Speakers and Google Nest Hub Smart Display for the "wireless" chime.

I have wired the Google Chime connector included with the doorbell in the box, in parallel.  Is that all I need for resistance on the line?

Warm regards,

Rishi
