which ones are amazon echo compatible?

From my research, the ones that are Amazon Echo compatible are:

1. Belkin Wemo Light Switch
2. TP Link Smart Light Switch

I was considering both, but the size of the switch and fitting is bigger than our normal light switches (at least in my house).
And also they require a neutral wire for it to work.

too expensive and not very nice looking.

i've been using wiwo switches just for turning off/on. would have been nice if they are echo integrated

I know this is super old post but hopefully TS still on lowyat. Did you eventually pull neutral wire for your switches? How much did it cost?

See the home automation thread.. nowadays u can get smart switch w a capacitor inside that works without neutral.

Pulling neutral from 13A socket or Aircon swirch nearby still OK, but don't ever pull from water heater switch because WH circuit is sacred (it operates with very tight leakage tolerance to protect against faults when you are in the shower).

oooo, so the non-neutral works on capacitor? I read online somewhere that it works on variable resistance, so there might be flickering issue. Would the capacitor reduce the chances of flickering?

If you choose the wrong type of capacitor, it will flicker. That is what happened to me recently.

Recently I bought ZigBee smart switch that works with both neutral or no neutral. No need to install any capacitor at all even though my setup is no neutral. Just replace the switch and done. It's a 3 gang switch connected to fan, led downlights and t5 L box light. No flickering so far 😁

If your lights are of higher than 5W, then high chance you won't see it flicker.

Not necessarily, some switch specs says minimum 10w. Read alot of shopee comments saying having flickering issue. Better confirm the specs before buy to avoid disappointment

The switch I bought specs says minimum 3w to avoid flickering issue. The best part is no neutral and no capacitor needed 😁

Update us in 6/12months see got issues or not

Sure, if I remember la 😂

Dunno how reliable are these smart switches. I read in the unified thread, those expensive terncy with neutral also died within a year 🤦‍♂️

Now you see it flicker cuz it's still outputing more than 5w. Over time it will degrade and you will see it flickering... It's all about time...

so I'm assuming this is using the variable resistance method?

Sorry, this switch not for is not dimmer switch
So far I see ZigBee dimmer switch does require neutral.

no no, I meant the way non neutral smart switch work. I read somewhere that the way they keep the smart switch "on" in non-neutral connection is by using a variable resistor. So when it is physically turned off, the switch will have high enough resistance to prevent the bulb from lighting up but still enough current to keep the chip powered.

Oic, not sure about that though.

Here's the link, maybe you can read up what the spec mentioned or you can contact the seller. Seller quite responsive with questions.

alright, thanks for the link!

Hi sifus, for aircons do you need a switch with neutral or without a neutral? Recommended to have the switch on its own or can be group together in a 2/3 gang with other appliances?

In general, what appliances will need a switch with neutral?

Thank you.

For AC it is not required neutral, but if you have a neutral then u can get that little red LED to work.

For WH water heater mandated 20A double pole switch by law.

Lain lain (13A SSO, lights) switch no neutral.
