Using existing hardware for 2nd generation doorbell

[Maniaccmike]

Hello! 
I currently have a nest hello, wired version which I installed myself. Unfortunately it has become defective and I have replaced it with the 2nd generation doorbell (wired).

Obviously with all new products, you will get new hardware as well. Since I had the nest hello installed; would I be able to use the existing wiring (in the chime box) or would I have to use the new hardware that came with it? Trying to avoid installing redundant hardware.

TIA!

A Google Nest Support Specialist should probably answer it.

However, the chime protector for the (1st gen) Google Nest Hello Doorbell has 4 wires, whereas the chime puck for the 2nd Gen Google Nest Doorbell has 2 wires, so I don't know whether you can use the 1st gen chime connector for the 2nd gen doorbell. (We have Nest Hellos.)

Ahh! That would make sense. I did not take a peek at  the existing connections before posting this. I will play it safe and just use the new hardware that came with the new doorbell. Thanks again for your help!

Hello Maniaccmike,

Thanks for reaching out to the Community. I just wanted to follow up and check if you still need assistance.

If you’re replacing the Nest Doorbell (wired) with the Nest Doorbell (wired, 2nd gen), you’ll need to remove the chime connector that came with it, too. The Nest Doorbell (wired) chime connector isn't compatible with the Nest Doorbell (wired, 2nd gen).

Here’s a handy guide to help you install the Nest Doorbell (wired, 2nd gen).

Reach out if you have any questions.

I appreciate your help, MplsCustomer.

Best,

Lance
