With that wire in the picture , it is pretty easy to install the cam now.

Get the transformer in lelong as idoblu mention (quite expensive) and a plastic electrical box that big enough for the transformer.

From the picture got 5 wire. The top 2 yellow wire is go to the outdoor switch 24v. The 3 wire below is live, neutral and earth 240v.

For the rest of join wire and case up the transformer, get a electrician if you not experience.

Gotcha. This will be something I look at if the alternative below fails. Been searching all day for a mains power unit (with built in transformer) with 220-240v in and 16-24v out but failed to find any. The combinations are typically 220-240v in and 8-12v out, or 110-120v in and 16-24v out.


Will do - once I have a good run of it integrated with the Doorbell. The Smart Lock itself, for now is alright in reliability. I DIY'ed the deadbolt and idk if it's too tight or something but the smart lock fails sometimes in unlocking the unit. Then I'd take the handle of the door, pull it tighter, then it'll open. Like it doesn't have enough power, but this might be due to the tightness due to a DIY'ed deadbolt.

Duly noted, tried to get numerous wireman to take on this task actually but all rejected. Also, this is an indoor condo doorbell so should be better.

Oh - that simplifies the explanation a lot.
Does that mean by putting the transformer there, I do not need to buy the door chime anymore? (And thus no ding dong when the door bell is pressed)
As for the lelong transformer, would this one from Amazon UK work as well? It looks much more... professional and reliable.

Bro Ozak have given clear instructions and the above is true..

buy an AC doorbell with built in transformer and chime(ding dong)

- wire up the 240V supply and switch ( if you have the correct doorbell the switch voltage should be 24V or lower, ac or dc)

- done..

Edit * the only reason a wireman will reject this simple job is if you are paying less money..

I don't know if you read, but "Bro Ozak" recommended on the last post to just buy a transformer and use that, and not what you proposed.
Also, you don't seem to try and understand the requirements either, since like I said, there isn't a 240V main supply doorbell with built in transformer that has a secondary voltage between 16V - 24V. The two combinations that I can find upon hours of research were:
220V-240V main supply - 8V-12V secondary voltage
110-120V main supply - 16-24V secondary voltage
The combination that I need to make this work - seeing that we're in Malaysia, and our mains is 220V-240V, and the August Doorcam requiring 16V-24V does not exist as one of the combinations.
Hence I can't just "buy an AC doorbell" because the combination required does not seem to exist.
You're also spreading misinformation by saying that the switch voltage should be 24V or lower, AC or DC. Firstly, AC is required and DC does not work. Secondly, it clearly states 16V-24V, and anything lower than that will not power the doorbell up. That means I can't just "buy an AC doorbell" which secondary voltage is 8V-12V and use it since it won't be enough power for the doorbell.

Now, I am trying to get a feedback to see if the transformer I linked should work as well, based on Ozak's last post regarding the fact that I can just use a transformer at the end point instead of a AC doorbell with built in transformer.

Uh, okay. I'm sure you've tried explaining what's needed to the wireman and they have accepted the job before.
What arrogance in determining that I am paying less money. Before the money conversation even comes up, they already rejected saying they don't have the expertise to do it, or that it's hard to find a suitable transformer. Don't know what your comment serves other than to be negative when you know nothing of the facts.

As with your prior random "warning" about wiring up the doorbell at 230V outdoors when my entire circuit is indoors within a condo, it clearly shows that you do not read at all and just try to be a smartass here. You're contributing nothing and is spreading misinformation towards others that might be using this resource next time to wire up their own units.

Since you don't have the chime, than you don't need to get 1. People recommended the chime is
1) if you already have the chime and modify to use for the August cam.
2) internal chime have the transformer. So you can make use that transformer. The others parts is useless after modify.
3) the chime box are look nicer to be hang on the wall. Than a plain plastic box.
4) buying the chime is cheaper probably than a transformer and a box.

Once you modify the chime for the August cam, the chime no longer will sound. Got to understand this. Cause you already bypass the solenoid in it.

The Amazon transformer also can be use. But you got to check the August cam power usage. The August cam pic doesn't show the power usage. The Amazon transformer only supply about 8w or 0.33A. Compare to the lelong which supply about 80w.

If the August cam use below 8w, you can go ahead get the Amazon transformer.

You are trying to diy wire a doorbell with mains voltage and asking for advice in a renovations forum.. and you rant? Wtf?

When you're done get someone with electrical knowledge to check your installation..

Seriously ..

Regarding the chime - most chimes that are sold here in Malaysia are 240v primary but their transformers seem to be 12v secondary. Hence the transformers don't seem like they would work with the doorbell. No luck on finding a 16-24v secondary chime yet. Thus, like you said if I buy the chime, probably for the box, and then discard the transformer (since I need to replace it with mine) and the chime itself wouldn't work since the voltage is different, right?

Also, after some research:
The spec sheet given here that I could find (http://august.com/wp-content/uploads/2016/03/August-DoorbellCamSpecSheet.pdf) shows Power Requirement 16-24VAC ~ 50-60Hz 0.2A, thus technically the Amazon transformer would be enough.

Right now though, trying to find something accessible locally, I have so far found a bunch of transformers that I think would fit the bill including this:
http://my.rs-online.com/web/p/din-rail-pan...ormers/7762966/ - 25VA
or
http://my.rs-online.com/web/p/din-rail-pan...ormers/8802618/ - 63VA
or
http://my.rs-online.com/web/p/din-rail-pan...ormers/8802609/ - 40VA

Out of the 3, I believe any of them would probably work fine based on the spec requirements. Schneider is the only brand I recognize between the 3 of them, but the price is also significantly higher, and for some reason the 63VA one is cheaper than 40VA one. My current plan is to order one of the 63VA one and use that. I will try and ask a wireman to install for me, or do you think I can probably connect it myself? I assume 'DIN rail mounting' means there is some way for it to be mounted onto the circuit breaker area.

Wouldn't something like this be much easier?
https://my.rs-online.com/web/p/plug-in-power-supply/7300247/

Yes.. just buy a 3 pin ac adapter (anything between 16-24V AC output rated for 5W)..

connect wire in the switch and chime..

or find a laptop adaptor rated for 19V DC, steal its transformer for free and wire it in..

If you can't find the chime with the suitable voltage, than forget it. Unless you want the chime box to make it nice.

The chime wouldn't work together with the August cam is because you modify it. Not the voltage different. The purpose is to use the Chime transformer. But once you modify to use the transformer, the chime solenoid that strike the bell will be disconnect. And the 2 wire suppose to connect to switch outdoor become a 24v supply wire for the August cam.

The 3 transformer you suggest is working find for the August cam. It well over 0.2A.

But the transformer size is freaking big and heavy. Are you sure you want it to hang at the wall? Even the 25VA size is consider big. No chime box can cover all this 3 transformer. Better check the size.

DIN rail is a long bracket for mounting the electrical component. You need to drill 2 hole to screw the rail to the wall and hook the transformer on the rail. It come in 1meter and material is either metal or aluminium. Price vary from RM5 to RM20. Which RM5 is freaking thin and soft metal. You wouldn't want it to mount the heavy transformer on it. Cut the rail to your desire length.

I think DecaPix suggest the adaptor is much more suitable. Cheaper.

I m not sure your skill. (you didn't mention here) Better just get the electrician. Even it is easy wiring.

Till this stage, any electrician can do the wiring.

Specially for DecaPix suggest transformer. Get a wall socket install, cut the adaptor wire and joint to the outdoor 2 wire. Than plug the adaptor to the wall socket. Parts less than RM90.

Thanks for the info. Considering this but trying to figure out how to wire it as it's outdoors, with no sockets around.

I have 0 skills in electrical wiring. Trying to figure this out as I have tried reaching out to renovation contractors / electricians and all of them shrugged and said they don't do. If I could buy this transformer recommended by DecaPix and then pay an electrician to have it setup without the headache for me I would do it in a heartbeat.

The question to me is, since it's outdoors (the doorcam bell), like literally outside the door, that would mean I would need to get a contractor to hack the wall to put in this cable and somehow go through the wall towards a socket near the door?

Or do you mean I can literally splice open this transformer's end wire and use it to feed the 2 yellow wire of this part:

and somehow figure out how to use the other 3 wires to power up the UK plug adapter side as well?

Frankly, if you have no knowledge of electric, please don't play with live voltage or diy. These things kill. If it not wired properly you may end up shorting people pressing the bell.

To be honest, my plan is to basically come out with a plan then ask the electrician affliated with the renovation company I used (he installed a few power sockets for me just 2 weeks ago) to actually do it. I approached him with the problem and he just said he cannot do. I know my limits and live 240v isn't a joke, I understand that.

If no skill, than don't touch at all. Keep on looking for the electrician that can do it for you. I don't understand what so difficult with such easy wiring. Probably you didn't explain much to them or your explanation to them too complicated ?

Your outdoor should have the doorbell wiring already. Given the picture you post. There is no hacking or wiring to do at all. Please check your outdoor where the wiring goes. Either the developer leave the wire like that (picture) for outdoor or already have a wall mount doorbell socket switch. Take out that doorbell switch and replace with the cam.

Even I show you the wiring below picture, you still have to use multitester to check and confirm the wiring which is which. Cause that yellow wire can make people mistake and confuse. (There are too close).

That diagram makes total sense.
Outside, indeed there's already a doorbell switch (which should be removed and replaced)


Will ask electrician about this.

Thanks!

This is why my sifu is a genius

Bro Ozak,

The AC Supply => adapter => wire to the switch => the chime

===========> adapter => wire to the chime (to close the circuit)..

" switch is between the adapter and the chime"

Wire the switch from the secondary coil of the transformer only.. The primary coil voltage will kill..

Usually doorbell (in malaysia) already have the small transformer inside, which it will be connected to outside switch, once the door bell press, it will complete the loop. If not press it will not waste any energy.

Use different region device without knowing how the current one work, the wireman sure will not want to touch it. Any issues is the wireman issues.

Me not sifu la.

Me some kucing kurap understand basic only.

Sorry I don't understand your connection.

What I understand about TS is his August cam require power to run. The August cam is all in 1 doorbell. The August Cam is wifi to router and to TS phone.

So no chime or doorbell switch. Not require at all.

The connection will be

The AC Supply => adapter => wire to the outdoor => the August cam.

Hope not kill him.
