Battery powered lock can last at least 6 months, if door is not frequently opened, it will last 1 year or more.

I have samsung fingerprint door lock, the battery can last 18 months. it is 4 x AA battery.

Thks! I'm just worried that China digital lock not that secure. Are they secure? And if suddenly use halfway and spoil, all I have to do is call the installer and they can see if need fixing right?

Make sure the lock hv redundancy built in, eg can use a 9v battery in case the battery fails, or use a physical key etc.

if u want secure, go search for the lockset that review by jerryrigeverything. very comprehensive review and stress test on the lockset.

Only issue I can think of is when turning the fan regulator (speed), the light will flicker a bit but other than that, no issues.

Not sure, capacitive type kua because put capacitor there the fan speed drop then move the cap becomes OK

Hello..Anyone knows if it's possible to change this aircond switch to those smart switch?

Any recommended system to use if I want to explore changing my wall switch for the fan (old fan) and light (fluorescent) in the room. Quite like the Xiaomi Aqara but the plug point seems to be an issue for certain items like the gateway hub/smart plug/ etc as I'll need to get a converter.

I have changed my aircond before. This starter was for a much older aircond. The current one also probably has been about near 10 years I think and if not mistaken it's 1.5hp

Those smart switch for Autogate normally use 10A relay. Don't think can use for aircon unless got higher amperage?

Ya bro, on the back it does say 20a printed on the plastic casing, reason I ask is bec there were 2 online sellers who told me there were some with lower amp, cant remember was it 10a or 16a, looked the same but slightly cheaper, just wanted to confirm and also make sure those who buy are aware. I have installed both Ewelink and Tuya, difference is Tuya can set off delay, as in wait for AC to completely shut down before the 20a switch shut off so I can use GA to switch on and off both via routines.
This is what I see at the back, thought there would be some resistor or something with 20a. Anyway doesnt matter. Thanks.

Didnt realise can remove the 2nd PCBA until you mentioned the screws, I can see it now

How many HP is this aircond? If below 2, can use real 16A-20A smart switch. Get the magnetic relay type so you can check it's relay rating to be very sure.
Smart switch

For aircond is better to get the one that cut off the neutral as well.

Is there any benefit from using 16A Smart Power Strip compare to 10A because the plugtop is still 13A UK 3 pin. Unless I change the Plugtop to UK 3 pin round I don't see any benefits, right?

What's IHC?

Just received Smart Light switch but then now having issue cause my old light  switch panel full of live wire >.<

Using test pen and checked, so many live @__@
I wonder cause all are connected?

I wonder the green and black behind is neutral wire or not
Cause it doesnt connect to the current switch panel.
Only from top till down from the pipe in the wall.

Yea, i guess those are looping live wire from Main Live, right ?

And i just need to find those actual light switch for L1, L2, L3, L4 (which wont trigger test pen) ?

I actually saw the green and black wire behind as per picture 2.
Can i pull one out for neutral actually ? (Or i shouldnt touch)

Yea, there's one thick black behind actually.
But i think i need to consult some electrician probably.
Jangan main main later cut wrong and pull wrong 

Hmm, but yesterday when i am testing, all switch are actually OFF.
That's why confusing me why certain point still has live light.

Man, old switch panel kinda messy i guess..
