I'm currently using a couple of switches from Retouch, connected to a standalone Zigbee gateway (LAN cable) which is then connected to my Deco M4 router.

All these are managed via Tuya. Worked great for the first 3 months and then for some reason the zigbee gateway keeps powering off by its own, tried all the troubleshooting steps but to no avail.

Now I'm currently looking at Echo 4th Gen (as now I'm using Echo Dot 4th Gen) as it comes with built-in Zigbee Gateway features which means that I do not need to rely on a separate Zigbee gateway any longer.

Anyone currently using Echo 4th gen and utilising the Zigbee gateway features?

dont waste money... just use ur MyKad
they gv me 10 free cards, it still in the box 😅

btw i never use it, my preferred pass...
1. Facial Recognition
2. Fingerprint

I just had another incident with 3 of my smart switches. One 2 gang and the other were 3 gangs switches. MOES Zigbee smart switch.
1. The 2 gang gave out a black smoke and both devices are in OFF state upon failure
2. The 3 gangs both have blown caps and devices that are being controlled remained in ON state after despite blue LED is off (live in leaked into live out)







Now comes the question, is there any sirim certified smart switch available? If we purchase house insurance, will they check the switches we use (sirim/ce certified...)?

Had similar issues with other switches
The blown cap just needs to be replaced, should be easy to desolder
The exploded one, not sure why that happened though

i suspect the burnt switch could be something else..... not entirely the switch fault. my whole house had been using Moes switches for a year+ without issues and so far only the incident I reported above (which weirdly is the switch i use the least.... balcony light)

Looks like the switches using transistor/mosfet for switching load.
Do u happen to wired it for ceiling fan?

serious? mykad can pakai?? if so ill give it a try tomorrow haha

Aqara smart switch got sirim certified version if not mistaken. Its Malaysia version. But I'm using China version since it's cheaper haha.

Yes. Got 1 ceiling fan connected to every switch. Inductive load no good for thus switch?

u r using 3 gang, make sure all high load device connect to the last switch.

also u might want to use DC fans, the power consumption lower than AC.

the power that leak, it might due to capacitor.

Based on the image you shared showing a burned-out or broken PCB track, this damage is likely due to a high voltage surge, such as one caused by a lightning strike.

To prevent this from recurring, replace the damaged wall switch with a new one from a reliable brand of your choice. Additionally, add a MOV/Varistor (10K431K) between the incoming Live and Neutral wires. This applies if you're using a smart switch with a neutral wire setup. If you're using a bypass capacitor, however, the MOV may not function as effectively.



The MOV (Metal Oxide Varistor) will help protect your sensitive electronic devices by absorbing excessive voltage before it reaches them.

Be sure to select a 10D431K specifically, as other values may not provide the same level of protection.

NOTE: Those staying in condo or high-rise building may not require such a protection as the building management already installed some kind of protection to prevent the voltage surge to its tenants.

From what i know, inductive load is not good for transistor switching. But, im not too sure about this . Needs more digging..

I use sonoff switches for fans, but its ' relay' type switching.

Thank you, must try this, I wired up all my switches with incoming Neutral already. Only some need to fix up a smart switch. Will try this capacitor thing when I do. Thank you again.

good one.

any way for landed users to protect the power surge from db box?
i think mine using very high sensitivity at rccb 100mA or lower,
not sure if this will helps or not

Install Surge Protection Device (SPD) such as hager, abb brand. I have ABB OVR T2 SPD to protect whole house.

Any cards with NFC i think. For me I use my condo access card

nope.
in general
1. rfid reader can only accept rfid card.
mykad is rfid card.
condo access card is rfid card.

2. nfc reader can accept both rfid and nfc card.
best use with smartphone or smartwatch with nfc.
nfc biometric

beware of different frequency use by rfid.

I found them here: https://www.copper2u.com/aqara

An RCCB is not designed to suppress high incoming voltage spikes; rather, it detects any imbalance in the current passing through it—such as when some of the supplied current leaks to the earth wire via an appliance—before cutting off the power supply to protect the appliance.

For comprehensive protection of the entire house, a Surge Protection Device (SPD) is more effective. The ABB OVR T2 protection begins at 275Vrms, similar to the 10K431K MOV.

i see Aqara switches label with "matter over zigbee bridge", this mean this switches can support and create mesh for both Matter and Zigbee?
