Battery door bell not charging from existing wiring

CRBrooker

Hi everyone,

I have measured the AC voltage for the existing wires for my mechanic door bell, reading 9.8VAC 

When I connect the Google doorbell and measure across the terminals it measures 8VAC.

However it does not show as charging on the home app and therefore can't use the mechanical chime.

Anyone have any ideas?

Maybe it's because 8V is the bare minimum required (see Google Nest's requirements: https://support.google.com/googlenest/answer/9247132?hl=en).

When we got our second Nest Hello a couple of years ago, we had to replace our very old 10V transformer with a 16V 30VA transformer.

The battery doorbell is trickle-charged: https://support.google.com/googlenest/answer/11830989?hl=en

Hi there,

 

Thank you for your patience, and sorry to hear that you're experiencing this. I know that keeping your Nest devices charged is very important, and I would love to help you out. When it comes to keeping your Nest Doorbell (battery) or Nest Cam (battery) up and running, here are some articles and troubleshooting guides for the best charging practices:

  • This is a great article on general charging times for your devices.
  • This helpful article tells you how to save the battery with your doorbell or camera.
  • And this last article, will go over charging expectations when you may live in a cooler/colder environment which will address charging temperatures, etc.

I hope those articles help shed some light on charging and maintaining battery levels of your Nest doorbell or camera. Please let me know if you need further assistance.

 

Best regards,

Brad

Hi everyone, after a lot of research, I found that the DHT01AN-C is not compatible with the nest battery door bell. I have replaced the chime and transformer with the Byron 776 and it is now displaying as plugged in and operates the mechanical chime
