My electrician can't install my Google Nest Hello doorbell.


Apparently it doesn't come with a 24V DC connector to the chime, only 24V AC (which won't work in NZ).


From what I can see, my only option is to go for a Ring doorbell.


Anyone else got a Google Nest Hello doorbell working in NZ?

But that won't work with the Google Nest Hello, will it?

according to this article, it will.  Unless that is not your device.

Nest Hello has an internal battery which other Nest cameras don’t have. Hello is powered by your household wiring and uses low voltage wires that carry 14 to 30 V AC in North America, or 10.8 and 30 V AC in Europe.

Something to do with the chime.
It has to be 24DC, but it’s 24AC.

Oh well, it has to be the Ring 2 then.
I do have Alexa and I understand it integrates better with Ring anyway.
I just really loved the design of the Nest Hello.

The Nest Hello does not use dc. The following is copied from Google.

"Nest Hello needs to be powered by wires delivering 16 - 24 V AC, and at least 10 VA (in North America) or 12 - 24 V AC and at least 8 VA (in Europe).

Tip: A traditional doorbell system uses very little power, but Nest Hello has specific power requirements so the camera can continuously record video. You’ll need to check if your current doorbell system can deliver enough power for Hello to work."

Years ago it was common for the doorbell circuit to be powered from a small transformer. This is what the Nest product is intended to utilise if it is there or alternatively an ac plug pack. Unless you also have a door chime that needs dc so can't directly use the Nest supply I think there is a misunderstanding.

Yep, that’s what he said.
As it doesn’t use DC, we can’t get it to work with the chime.

You have an existing doorbell chime? Do you need to keep that?

What is the chime?

Edit. Quick search shows up others that have used dc for Nest so that a chime will work. You need to balance having enough power for Nest without overloading chime. So it can be done if you put your mind to it.

Don’t necessarily have to keep the chime.
Not sure of brand.
Is the photo of assistance?


Ah, it’s been rotated for some reason. Should be 90 degrees rotated.

Yep, but my electrician gave up, so I guess I’ll have to leave it.

I know this is going off-topic, but are you using an iPhone?

 

I've noticed that a lot with iPhones; I think they save the photo in a standard orientation, and then use the EXIF data to record the "correct" rotation for display - which works well on the iPhone and other Apple Products;  but not so much if/when the EXIF data is lost, stripped, or otherwise unused.
