sorry to kacau, just for personal knowledge.
but your method this way removes the 2-way function correct?

To complicate the method further, now have new single fire switch that need put this wifi power adapter between L1, no need use capacitor.

can we use sonoff smart switch to open close autogate?

can share which model?

this is strange, does not have that thing

Nope

I didn't use their driver

straight away sonoff to the light

I thought sonoff act as the driver?

salah?

Had mine for 2 years now, never had to replace them.

However strictly use it on lighting only, I have seen people using them on ceiling fans and what not they die within 2 years due to excessive voltage load.

Probably but which regular ceiling fan use high wattage? 

I have a device that is powered by a 9V 500ma power supply wall adapter.
I would like to connect the device directly to the house wiring without using the wall adapter. Can you guys recommend me any device that can convert the AC to DC.

Ok thanks, I'll try to understand 😁.

One question tho, assuming 3 gang no neutral with capacitor switch, can use on any gang right? L1, L2, or L3 or only L1?

Should be any line. Just to leak current to the switch to power the switch circuitry as far as I know at least on my dumb touch switch. Maybe expert can advise better 

Can 3 way smart switch has separate phase on each switch? If so, then would it be a problem? 

My bad, I meant 3 gang smart switch.

So, my question was can a 3 way smart switch independently work on 3 different phase?

So was trying to install my aqara switch today. Didnt work.

Understand that the yellow wire is the live wire while the red goes to the switches (L1 and L2) accordingly. Howver they seems to be an extra red wire to the comms of the okd switch which im unsure what it is.

On one of the switches it did blink red for awhile but nothing after that.

Anyone can advice?

yeah aqara too expensive. for wifi i see this 1 RM42.90 (2 gang) seems cheap.

let's say i got 2 light in L1, can i put the capacitor (come with light) at 2nd downlight?

Just tested to tap the neutral line from water heater switch, the water heater ELCB will trip. I believe the water heater ELCB detected the current leakage as the wall switch use some current to operate. No problem when I connect the neutral line for the air-cond switch.

The circuit is originally from developer. TNB -> Main ELCB -> Water Heater ELCB  (both ELCB are in DB) -> Water Heater Double pole switch -> I tap the neutral from this switch and cause trip.

by the way this driver come with 2 wire inside, small driver. and it have brown and blue. so brown is neutral, blue is live? this is how i connect to sonoff.

Socket off


Socket on, sonoff off


Socket on, sonoff on

To all the pros out there, need ur advice again 😬😬😬

Having issue on replacing traditional switch to this smart switch.



Clearer pic of the wiring on the old switch. Texted with testpen and only the red one light up.

Do I need to put capacitor?

This is the seller.

If u say it’s for looping, then replacing to the new switch no need to do looping ?
