Nest Hello Doorbell - No idea how to setup
Discussion
Evening all.
I've recently moved into a new house, and tried to setup as much home automation as possible. I've got a load of Nest products, linked to Echos and Hues etc, however I am completely stumped with the Nest Hello.
I ordered it without checking any details and thought it would be an easy install. I now find it's not setup to be an easy install in the uk due to the power requirements of the doorbell.
So I'm at a loss on the best way to get it working really. I have a chime which is battery powered as below. This can't power the Nest Hello. What is the easiest way to get it all up and working, with me being a huge novice at DIY

The Nest Hello has to be hard wired. You will also need a transformer. I looked into one but the price and the hassle put me off.
If you go to the Nest website, I'm pretty sure you will find details of local installers and I am led to believe they charge a flat fee for installation, although I might be wrong.

I fitted one last week. It is not too hard once you understand the way it should be wired. The instructions supplied by Nest (and their online videos / app) are complete crap.
The Nest Hello requires a higher voltage than the voltage supplied by standard UK door chimes. If you have an existing door chime that supplies 24v AC then you do not need to buy a separate transformer and the instructions supplied by Nest should work for you.
In my case I didn't have a wired door chime at all so I had to buy a new Door Chime and a transformer. I ended up opting for the following:
Transformer:
https://www.screwfix.com/p/british-general-8-24v-8...
Chime:
https://www.screwfix.com/p/byron-776-wired-wall-mo...
I removed the transformer from the chime (it only supplies 8v AC) and discarded it.
The Nest Hello should be connected as follows:
I connected this up on the kitchen table before wiring it in to ensure everything worked correctly. Be very careful when connecting up the transformer as it is supplied by mains.
The transformer does not have an easy way of mounting it to the wall and it is not supplied with a box so you may want to add one.
The internal wiring of the chime looks like this:
I still need to add a resistor as the chime is very loud because it is being powered by 24v AC (as opposed to 8v AC).
It has now been up and running for about a week. When it is working it is great BUT I have noticed that it will go offline from time to time and needs to be power cycled; this is probably down to dodgy firmware and very annoying.

It’s not a flat fee unfortunately. They just send your details to local ‘Nest experts’ who they send you the quote.If you go to the Nest website, I'm pretty sure you will find details of local installers and I am led to believe they charge a flat fee for installation, although I might be wrong.
The cheapest I have had is £179. I’ve already paid £229 for the doorbell. Would prefer to not have to stump up £179 if it’s possible to do myself

Can I just ask, did you connect your transformer to a plug and just plug it in near the doorbell, or did you connect it to your mains circuit?
Does anyone know if you can just use a transformer and miss out all the doorbell stuff?
Just thinking, I have some spare room in my consumer unit which I can mount the transformer and its right next to my alarm panel where I have cables which are no longer used for the front door sensor which are run into the door frame.

I believe you can miss out the chime - if you do you will need to rely on your phone/tablet/google smart speaker.
We have a Ring doorbell at the moment, so the nest would be no different
Just fancy getting the Nest one as we have a few of the cameras and they stream to google home.jesusbuiltmycar said:

I've just stumbled across this post and you have the same setup as mine, however I can't seem to get my chime to work.
I've got a wire going into the 24v port which goes to the chime, and a wire going into the 0 port going to the Nest hello.
I've then connected the wire which comes from the 24v transformer to the grey terminal on the Nest chime connector and the wire coming from the Nest hello to the white terminal on the Nest chime connector.
I've removed the transformer from the chime, connected the grey hook on the Nest chime connector to terminal 3, and the white hook to terminal 0. Terminal 1 and 2 have nothing connected to them.
On the Nest app I tapped the "Indoor chime On/Off" and the button next to it is blue/on. "Chime duration" is off. "Visitor announcements" is on.
By doing the above I've managed to get the Nest hello to work with my google home, (when someone rings the doorbell the Google home announces someone is at the door) however I can't get the chime to "ding dong". I'm not sure where I'm going wrong.
If you could shed some light as to where I'm going wrong I would much appreciate it.

It sounds like your setup is more or less correct (since the hello doorbell itself is working) but the chime connection itself may be wrong. I've just stumbled across this post and you have the same setup as mine, however I can't seem to get my chime to work.

When I configured mine I did it on the table and discovered that I needed to use terminals 3 & 0 by trial and error (the original transformer that came with the chime used 0 & 2).
BTW i recently upgraded my WiFi and the system has been 100% reliable since then.

I’ve been looking at this however it’s the mounting of the transformer which really puts me off. I have a fully hard-wired doorbell, and would need to replace the chime anyway as the transformer is fully integrated.
Where are people mounting the 24v transformer? Plugging into a socket isn’t an option for me, and as I have the wiring already I’d like to make use of it

@jesusbuiltmycar on mine the original transformer used 2 and 3. I can see there's another wire that possibly connects to the bell itself and that's on 0 and 3. I've tried everything but cant seem to get this thing to work. I thought the chime may be broken so went and got a new one, but still have the same issue 
@Juggsy I got my transformer under the stairs next to the consumer unit and have ran a wire from that to the bell.

This is the bell transformer I used:

I can't remember which terminals the original transformer was connected to but the Nest circuitry is now connected to terminals 0 & 3.

I assume most of you system is on place. Since you mentioned that teh Nest is working OK I suspect that the problem is either the chime or the disc like module that connects between the transformer/nest hello/chime.
To fault find / diagnose, could you try the following:
1: diconnect the 24 output wires from the transformer
2: disconnect all wires from the chime (and take the chime off the wall, so that it can be temporarily moved close to teh transformer)
3: get a spare length of wire
4: connect the new to the transformers 24V AC output
5: touch the ends of the new wire to treminals 0 & 3 of the chime - if it rings then that confirms that the transformer and chime are ok

I had mine installed in West London a couple of months ago for about £120-140 IIRC.Nice Romanian dude said business was off the scale since the Google boxing day sale and I was his 11th install of the day. He said he was installing Nest products from 7am-2am the previous day as well.
Hello works well but I do notice the 15-20 second lag from the bell being rung to it appearing on my iPhone and Google home.
