Doorbell (wired, 2nd gen) and two chimes -- how to wire? (One chime works, other doesn't)

[JBA285]

I have the 2nd gen wired doorbell, and the chime connector / puck only has two wires. The doorbell works fine, but the chime behavior is weird:

- On the chime that has the puck, it doesn't ring at all when the button is pressed

- The chime without the puck rings when the button is pressed, but otherwise hums the rest of the time. It's because the chime plunger (the mechanical part that strikes the metal "chime bar") is bouncing up and down slightly.

- If I don't use the puck, the chimes will randomly ding, so that's probably not a good option.

- I checked the voltage on the bare wires at the doorbell before installing and read 19V

I've tried looking at this thread, https://www.googlenestcommunity.com/t5/Cameras-and-Doorbells/1-nest-doorbell-2nd-gen-2-chimes/m-p/25... , which pointed me to this support article, https://support.google.com/googlenest/answer/12153643?hl=en, but none of those explain or show a one doorbell and two chime situation.

I also found this, https://www.googlenestcommunity.com/t5/Cameras-and-Doorbells/Need-wiring-diagram-from-wired-nest-doo..., but that's for the previous gen with the puck that has four wires.

How is one meant to wire the 2nd-gen doorbell to two chimes?

If your second chime is daisy-chained after the first chime as shown in the Nest Hello example below, perhaps you should connect the chime puck to the first chime (the one directly connected to your doorbell).

Your link is one of the ones I already mentioned -- the puck I have only has two wires (I guess that's new with the 2nd gen), not four wires. Unless I'm misunderstanding something, I don't see how I could make that diagram work with this two-wired puck.

If I move the puck to the other chime, then the problem just moves to other chime that no longer has the puck.

If I remove the puck entirely (which I think the instructions say is a bad idea), I get half-chimes from both boxes, and both boxes are humming/buzzing

Yes I know the new "chime puck" for the 2nd gen doorbell has only 2 wires, while the "chime connector" for the older Nest Hello has 4. I referenced the 2-chime diagram for the Nest Hello only to suggest that, if your second chime is daisy-chained in sequence to your first chime (as in the diagram), then it would seem that wiring the "chime puck" to the Front and Trans posts in your first chime should work, similar to the sequence in the Nest Hello diagram.

However, judging from what you describe (where either of your chimes work only when wired with the "chime puck"), your chimes may be wired in parallel (and perhaps you even have separate transformers for each transformer). The half-chime and buzzing are symptoms of not having the "chime puck" or "chime connector" wired.

Maybe you need a "chime puck" for each of your chimes. You may need to contact Google Nest Support (https://support.google.com/googlenest/gethelp) to get another one, unless a Google Nest Community Specialist chimes in on this thread.
