Is not the safest and convenient choice.

Why have to do all these trouble? Get one with 4 wires will do

You mean 3 points plug socket? I have one outdoor but is not expose. Have to switch off from inside when not use.

Yes, I have 2 3point plug socket outside but not exposed, currently have weatherproof cover-the plastic type. I believe one socket is for the future mini water feature outdoors. But don't know why need one more 3 point plug socket.

After seeing the concerns over weatherpoof cover etc, makes me wonder whether I should ensure extra protection.

I have a doorbell switch under Pieno range by schneider but not sure if also need to have cover?

If you are running low voltage door bell, don't need to have cover. Or if the switch are design for outdoor weather resistance. Even if you need I am not sure you have a direct fitting cover for that switch. Usually are universal and is slightly bigger.

This one is something solid

Door Bell is 10A 250V. That link you provided looks solid but need transformer right?

The 3 point plug socket is 13A 250V

Door bell can handle that but you don't need that amount current. Most Important is it design for outdoor for 230v? If it leak out during raining someone pressing the door bell may get electrocute.

This one I am not sure? What should I do then?

Since you like and desperate for that doorbell.
Here you go...



Referring to above schematic:
● The doorbell switching done by AC relay.
● Relay energized by step-down transformer power supply.
● Outdoor switch running on low AC voltage.

Thanks for your schematic diagram.
As far as I know the 230v AC to 12v AC step down transformer is small enough to keep in the door bell box. BUT how about the AC relay? does it small enough to keep inside the door bell as well. I heard the AC relay need power supply, is it true?

Relay need power supply to energize the magnetic coil.
I think the transformer and relay can be fit into the casing.

Could you remove the small black plastic cover and provide me the picture of the circuit?
If you refer to first post (two-wires type) by TS, you can see the circuit of the unit.
I have another idea to modify the circuit to let the switch run on low voltage.

any wireless doorbell recommended for landed house (waterproof)?

I tried to use a wireless doorbell for landed house, but it failed miserably.

Not due to waterproof issue.

I sealed the button press unit with glue and it is waterproof as far as I can see.

But the problem I had was the battery. After using for a while, the dry cell voltage got out of operating range for the remote. I suspect it's due hot sun, the battery loses too much liquid and therefore the circuitory refused to work. When I open up the remote unit and change the battery, it works again. Multimeter the battery shows the voltage too high. It's not a case of voltage too low.

oh ya... battery really is the issue when explore under hot sun. I think we should go for this type--->Battery-free Wireless Doorbell

Never tried that before. Not sure if it is reliable.

The other thing to consider is the signal range. For landed, the distance between the remote and the receiver is normally much further than a condo unit.

why a hassle buying door bell ?

1) your hse should supply 5 wires , 2 wire ( from outside switch )
2) 3 wires ( L / N / E )

then

u buy legrand bell(build in transformer) . has 4 connection. 2 input for L/N (polarity does not matters here and it is used to convert 240 to 12V dc ) and 2 input for switch ( for connectivity )

legrand bell vs door bell, what's the difference ? Is it legrand bell a door bell too ?

Why you consider door bell a "hassle" ?

I Just bought from Tao Bao yesterday at only RM70/set. once I receive I will try it and let you know:)

Good good good ! I want to know.
