Since i just got TNB smart meter, would like to share PZEM-004 power usage meter vs TNB smart meter..  For home I think good enough.

Any ideas converting dumb doorbells to smart ones?

Seen some people recommending putting a contact sensor right in the door bell ding dong.

Problem would be the power for the ESP device with relay

Just regular dumb doorbell with chime, so powered by mains.

Hi Sifus,

I'm planning to try out smart switch for the bedroom which will control the lights and ceiling fan, but the more I search Shopee and the forum, the more confused I become. As I understood all Aqara switch needs a zigbee gateway/hub. Which hub/gateway is recommended? My house is a double storey 22x75 and that hub will be placed on the ground floor middle of the house. Will that be good enough for the wireless transmission to all rooms upstairs?

Also I checked my switch plate, and below is the photos. I guessed there is no neutral wire. Some switches I saw on Shopee that for no neutral wire requires a capacitor to be install. Does this apply to Aqara no neutral switch? As my house have a 15A socket for the aircond, I'm doing reno and asking the contractor to change that and make it a hidden wiring for the air cond. So they will add a 20A switch besides the lighting switch. Can I just use the neutral wire from the air cond 20A switch. My house is on 3 phase power. I went thru some video tutorial on 3 phase electrical and it seems 3 phases system have 2 types of connection method which is delta and star. If not mistaken Malaysia should be star right which have 4 wire including neutral? If that case, my question will be can I just tap the neutral wire from the aircond switch irregardless of the phase of the aircond and the light/fan switch?

I don't need any voice control, just needed a smart switch where each person can on/off their room lighting/fan themselves wirelessly. Any suggestions will be very much appreciated.

Hi. I’m planning to change my all my wall switch to Aqara as well as looking to add equivalent kind of switch for wall socket to control my plugged devices such as standing fan.

However I’ve only found socket that’s with China head (Shopee). Does anyone know if there is any Malaysia version?

Besides that if I use normal wall socket, is there any smart extension smart strip (4-6 socket) that can control each socket individually? I am looking for HomeKit compatible type hence aqara is my first choice.

Thanks. Haha I’m using those old school fan with button 123 to turn on type. Seems like HomeKit is not very commonly used for socket. Might have to consider getting a raspberry pi for homebridge.
Hi, thanks! Unfortunately these are for google assistant, doesn’t compatible with HomeKit. Maybe I’ll have to get a raspberry pi  to setup homebridge for it to work.

Might as well pay a bit extra for the feature.

can share why use 3 gang instead of 2 gang? currently have one switch to replace into smart swtich but is 2 gang only... thanks in advance...!

can't see any burn mark.
but it still can be use as a control.

What abt a normal wifi router? Any idea how many?

Zot
I'm wondering if the router hardware will get overwhelmed with the 200+ odd connections, curious.

I believe you are talking about IP address range /24, this is nothing to do with wifi router, if I assign /16, I can have 65534 hosts.

the limits of the wifi router is depending on its cpu, memory, most cheap home wifi router won't be able to run 255 devices reliably

wanna ask this yellow thing call what? coz now some switch quite congested. plan to use this to resolve some connection instead of using connector.

hi guys,
if plan to replace wall switch in double storey house, which one is better.
Either smart switch for wifi or zigbee?

for zigbee, might need two gateway since need for ground floor and 1st floor.
how about wifi?does it congest?

anyone had experience with aqara hub???
i used to off my wifi before sleep, but aqara hub will start blinking blue searching for wifi.
I had been clicking on the button on the hub to switch the light off.
is there a way to set it off and won't blink anymore??
Thank you

but then shouldn't we occasionally reboot the router as well?

noted.
so for new router, there is no need to reboot. am i right?
Thanks.

Hi guys,

Is there a device we can connect to the doorbell circuit and inform us when it is press??

hi experts...

so i got the smart wifi switch below
https://s.lazada.com.my/s.1AUbf

it comes with the capacitor.
my wiring doesn't have a neutral line. so i should install the capacitor near the appliance.

1. funny thing is, it also works without the capacitor just fine. any thoughts? is it safe? has it got anything to do with the kind of appliance that's connected? (it's just bulbs and fan)

2. another thing i noticed is that in one instance, when i do put the capacitor, the bulb it's attached to doesn't want to fully light up. it just blinks. these are normal osram pl2 bulbs. 2 bulbs to a switch.

3. one of the switches resets itself sometimes when on/off by hand and gets removed from the app. I'll need to readd to the app. any thoughts?

thanks
