2nd gen Wired Doorbell cam works/ doorbell does not

[Maeve]

I installed 2 x 2nd generation doorbell cameras which work just fine, but now my normal mechanical front / back door chime doorbell does not ring ….I have a 40 VA transformer

If you have two 2nd Generation Google Nest Doorbells as well as a conventional doorbell, you need to be careful how you've wired the doorbells.

Each of the 2nd Generation Google Nest Doorbells needs a "chime puck" that is wired correctly. Google Nest does not seem to have a wiring diagram for 3 doorbells, but the link below has a diagram for 2 Nest doorbells connected to one chime (it is incorrectly labeled "Two Nest doorbells, two chimes"):

I’m using a 40 MV transformer and my outside nest cameras are lit up and functioning properly ….making controllable doorbell noises outdoors when pushed, but nothing indoors 

the doorbells worked before I installed the camera…front and rear . Seems odd, no yellow lights, and iPad easily controls them remotely

So the "chime pucks" are wired correctly and the "Indoor chime" option is enabled on both doorbells? Sorry if this is asking you the obvious; nothing else jumps out at me.

I want to thank the customers who advised me on the installation of the two Nest doorbells and I want to chastise Google / Nest for not publishing proper information or having actual tech support phone number to call.

the problem was lack of amperage to drive the 2 nest doorbells as well as the 2 door chimes 

i replaced the one unknown amp transformer with 2 x 40 MA transformers …separately wired, and its now all set. 

I remember actual customer service vs service provided by customers …..

again, thank you customers

If you have two 2nd Gen Google Nest Doorbells as well as a conventional doorbell, you want to be sure everything is wired correctly.

Google Nest does not seem to have a sample diagram for three doorbells, but it does have a diagram for 2 doorbells on 1 chime in the topic below; the diagram is incorrectly labeled "Two Nest doorbells, two chimes":

Since I have 2 doorbells, I’m going to wire a second transformer as I suspect the single transformer is having a problem with the load of 2 bells and 2 nest cams …..I’ll update in a few days
