Thanks for the response. I suspect my house is on 3 phase house wiring, is there anyway to confirm that? Phase 1 development does not mention about the wiring, but phase 2 development explicit mentioned 3 phase.

The 3 phase master circuit breaker is bigger with 3 ganged switch like this



New housing is using RCCB not ELCB. The RCCB concept is comparing current going out to load and current return from load. If equal, then OK. If not it will trip. Some house wiring separates the 3 phase N, thus if you mix the L from other phase then return the current through N in another phase, the RCCB will trip. However, they may use common N for all. The MCCB in picture has 3 L out and 1 N. This I believe will have no problem. Probably some use 3 single phase RCCB, thus tis will cause trip. That is my understanding.

The 3 phase wiring will have 3 different L wire color like Blue, Yellow and Red. You can try connect. The worse is the RCCB will trip.

Mine 3 phase and only pull neutral from the ac next to light switch

What i know, pls look at your meter box, if you can see 3 big fuse box and have 3 big wire coming go thru it, it mean 3 phase. Sifu, is it right?

Yea... I was looking at inside the house. It is easier to look at the fuse. # fuses mean 3 phase supply

Thanks. Received the Raspberry Pi.

No idea how to start using it LOL

Whatsapp me, bro.

no aircond switch nearby. thats the switch at my house entrance

Out of luck then. Can check on Xiaomi switch.

Expensive Garage Door open by Ewelink app

i think ill get the switch and attach to individual downlight then. just leave the switch on.

Can also if u don't mind to toggle the switch using the app.
If really need a wall switch maybe use a Sonoff RF with a RF wall switch.
What are u attaching the Sonoff Basic with? Light?

Not invidual i believe since 1 switch probably control 2-3 downlight, put before the junction.

But sometime, this sonoff basic become not stable mean it did not connect to internet, and need to reset

Is this often, need to reset? You probably have the unit on ceiling, then it is a nuisance.

Since I've never own any sonoff and was thinking of a project for it, this makes me think twice

Need to reset meh? After install the Basic, I never physically touch it afterwards.

We never know, maybe that unit got problem. Other solution is to swich off and switch on back and hopefully it get connected. Most of the time it work

You flash already, not same meh

Maybe happen on 1 out of ten, nevertheless it stillcoolto have it, please proceed your project

At moment i put at my air purifier and table lamp mostly use the timer but not good for air purifier since i need to push the button to switch on

Nope. Never need to touch it after installed.
Flash with Tasmota also no need to touch it afterwards.
I think u got lemon unit if need to reset it or press the button on the Sonoff Basic.

So mafan one. Install a robot arm which connect to Sonoff to press the button.

Can teach mr how to flash with tasmota

Haha that one problem with sonoff basic for the appliance that require u to touch the on button. Off already auto but on still need manual

Check the video above.
Toughest thing is the USB adapter, sometimes can or cannot connect
