How to connect 2nd Gen Google Nest Doorbell (wired) to Honeywell wireless chime?

[LogCastle]

I attempted the installation using the wiring diagram I posted here: https://o51w5j.axshare.com

With these components is the Google Chime Connector still needed?  If so, is my wiring diagram correct?

I got the doorbell to install and the camera and integrated doorbell chime to work, but after about 30 minutes the camera went offline.  Though I was able to pair the Honeywell adapter to the Honeywell chime, I was not able to get the Google Nest doorbell to activate the Honeywell chime. 

My diagram is essentially the same as the diagram in the Doorbell Adapter installation manual, minus the Google chime connector.

I'm not an expert, but your diagram seems in accord with Google Nest's diagram AND with your vendor's wiring diagram.

You're dealing with very low voltage, but it's probably still worth it to turn of the electrical circuit when you're rewiring.

I don't think you'd need to reinstall your doorbell in the Google Home app just for the rewiring.

You might have to play with the "chime duration" to see if it's needed or not to make the chime work.  I don't know whether Google Nest's doorbell will treat your Wi-Fi adapter the same as an electronic chime or not, and Google Nest provides very little guidance in all of this; they just say, "contact a Nest Pro".

Hmmmmm, to the best of my knowledge the diagram is not the correct wiring.  I believe the 24V transformer needs both wires going to the Nest Doorbell directly.  Try this first and run it for a number hours or maybe a day and make sure the doorbell stays online.    

I don't know the correct wiring but I don't believe the chime connector is meant to go in-line the way you are showing it.  I think it is meant to go in parallel with the chime connectors.  At least that is how it work with a mechanical chime.

You might try watching some of the youtube videos on this as there is a lot of info there. 

You can also try reaching out to Google and speaking with a Google Tech person but because  this involves a 3rd party product (IE Honeywell) the  may not be able to help.  Here is the link it you want to open a support ticket and talk to someone....

PS:  If you get it going please return here and let us know how you solved it.  And maybe update your diagram if it in fact isn't correct.

Thanks for the idea.  Are you suggesting that I try to get the doorbell going (and staying online) without any chime and once that works attempt to add the the Honeywell chime adapter into the mix?

If I don't get any more input from anyone by noon PST today I will try the google support team.

Once I get this to work I will for sure include the final wiring diagram that shows what I did.

Google Nest's diagrams are on this post:

The diagram you posted does not apply to my installation because I don't have a mechanical chime.  I have a Honeywell chime adapter that sends a wireless signal to a Honeywell electronic chime.  I'm looking for a wiring diagram that shows how to wire the Google (wired) doorbell with a 24V transformer and Google Chime Connector to the Honeywell Chime Adapter.  Thanks!

I came across another post of yours on 12-18-2023 at 12:04pm where you said, 

"If you do NOT have an indoor doorbell chime and are connecting your doorbell directly to a transformer or power adapter, it seems that, given comments from Google Nest Community Specialists in this forum, you do NOT need to use the chime connector."

Do you think this scenario from your other post applies to my application?  I don't have a chime - but rather have a Honeywell wireless adapter (RPWL4045A2000).  So do I need to use the Google Chime Connector?

The post of mine that you referenced is when the doorbell is connected directly to a power adapter/transformer and there is no chime involved.

I'm not an expert on doorbells, but Google Nest does not provide separate diagrams for wiring to electronic chimes, and your wireless doorbell adapter is wired in the same way as a mechanical OR electronic chime would be wired, and you still need to send an electrical impulse to your wireless doorbell adapter when the doorbell button is pushed.

The purpose of the chime connector is to provide power to the camera in the doorbell during the instant when the doorbell button is pushed and power is diverted to ring the doorbell chime. In your case, power needs to be diverted to send an impulse to your wireless doorbell adapter so it can send a Wi-Fi signal to your Wi-Fi chime.

In your case, it looks like a regular doorbell should have one wire from the doorbell going to A1 on your chime adapter, and the other wire going from the doorbell to one pole on the transformer, and another wire going from the other pole on the transformer to AC1 on your chime.

To match Google Nest's diagram, I think you would then connect one wire from the chime connector to A1 on your chime adapter and the other wire from the chime connector to AC1 on your chime adapter.

That's the best I can offer as a suggestion.

P.S. And you might have to treat your chime as an electronic chime and set a "chime duration".

I added another wiring diagram that I think represents your suggestion.  Please let me know if this diagram is what you are suggesting.  If you confirm it is, I will give it a try shortly.  Before trying, should I first completely remove the device as if I'm starting from scratch? Thanks!

I have seen the setting for the chime duration.

I tried your suggested wiring diagram and the camera and doorbell are working fine, but still no signal is being sent to the Honeywell chime (I don't know if the doorbell is sending a signal via wire to the Honeywell adapter).  Further suggestions?

I updated my wiring diagram too.

I popped the top off the adapter and put it back on and it just started working!  See my last comment for the diagram that works.  Many thanks to MplsCustomer for the help!

Another option to consider is to just get a nest MINI speaker which will CHIME when someone hits the doorbell button.
