nope. 1 way.
thinking to use the 2way version for stair too..

yeah. our house wiring all 'shortcut' one.. like stairs 2 way switch. 1 end supply, 1 end load.. haaih..

Should be the right time to pull neutral wire to all or selected switch location..
Might be pulling lan/cat6 cable to certain selected location also..

Maybe very hard to do.. if the original wiring got piping, maybe abit easier, can 'fish' and pull new cable..
Else.. needs to 'hack' the wall to pull N cable to nearest point..

And somemore, 3 phase really pain.. N need to go to the same rccb L phase..

Really difficult and cumbersome jobs..

About zigbee smart switch, can the switch work with wifi or still need the zigbee hub?
If the hub 'down' all the switches lose connection and doesn't work?

Ic. Tq.
Looks like better take wifi version.
Im beginning to running HA for my home.

Tq.
Yeah. For light switches.. probably best using wifi.. my house seems doesn't have wifi blindspots.. router place in middle of house.
Currently im.running the HA on Debian on an 'old hardware' Celeron J1800 itx.

i prefer sonoff too.. but they lack mechanical wall switches.. mostly tuya have..

i prefer with 'border' haha.. just a preference btw..
quite pricey also..

but if pair together with nspanel very nice..

something like this.
border or rim around the switch.


*sorry for link. cant upload pic currently.

i see..
thanx for the heads up..

need to find others..
might go for the Switchman.. currently all my 'smart devices' are all on sonoff/ewelink.

For controlling higher power devices, u can wire the smart switch to 'contactor'. Its function like a relay.
Smart switch power the relay, the relay power the device (ex: pump/heater)

Im going to power my water pump this way because the switch is upstairs. (Currently need to go up to switch on pump)
With smart switch can power from anywhere (app or HA interface downstairs)

Will try to draw later and update.
Currently went back hometown.


I still need switch at upstairs becoz need ON waterpump when shower (low pressure from water tank).
Sometimes need extra pressure downstairs too for bathroom and laundry.
So with smart switch and contactor, i will be able to ON OFF either upstairs or downstairs.

With sonoff basic u can only control with 'app'.. and have to leave it powerd ON.

And 1 more thing, i can have standard 'switch model' around my house.
Thats y i will go with smart switch and contactor.

Using contactor also will protect my smart switch from hi load.


I will be using normal smart switch (for lights or fan).
This switch will control the contactor powering pump/heater.
I will have more control over my waterpump. ON OFF either upstairs or downstairs.

the contactor not place inside the switch box, but near the device or along the supply to the device.
ex; inside ceiling.
it goes like this, the contactor receive direct supply form DB or power source then to contactor (maybe on celing/roof/inside device casing) then to device, the smart switch wired to control the contactor (any normal/smart switches can be used, as the contactor is very low power device)

DB/Supply > contactor > water pump
,..........,......................^
....,.................. smart switch

(Ignore the dots)

hope u get what i mean.

i dont think so... unless TNB willing to give user access/API to their app..

have to use metering device (sonoff/tuya/etc energy meter) at DB and pull the data, some code/programming to calculate tariff and cycles..

correct.

u need to check the 3rd switch neutral. izzit confirm from 3rd rccb?
try dismantled 3rd switch and reset rccb.

Ok.
Tried remove 1st switch, can reset back mcb?
The AC switch supply, use normal mcb or rcbo?

Btw, which switches u replacing? Light, stairs,..?

i think u need to get dimmable downlight/bulb.
nowadays LED light using wide voltage input driver.. so dimmer cant work in this normal driver. need specially dimmable driver.

old tech light (filament) sure no problem..

im using 1 inv midea ac. i dont think media one need subscription. still free to use..
aih.. didnt notice got esp mod for media.. if found earlier doesnt need to buy the wifi adapter

but Daikin only free 2 years premium subs. (after that only can use on local network) and Malaysia version wifi dongle/built-in also doesn't support in HA
