thanx bro...

another questions here, lets said i have 2 db.
currently the second db tapping power from direct power source.

but it is recommended to tap the power from the output on first rccb?

this is my personal opinions...

dont go for capacitor, imagine if u have 20 or 30 switches.
when the time capacitor burned, will u still able to remember where u put the capacitor? u might remember now, how about 2years to 5years down the road... or mayb more??
and do u know that u cant use L1 for fluorescent light, and mayb some other devices.

man, this is sick 😍😍😍
rm160/unit, i wish i can upgrade to this too.
my reno over budget ady... mayb next time

i also not sure why it doesnt work on fluorescent light.
here just my theory, mayb when the starter ignite the argon/xenon gas. it will pull ALL power from the L1 and might cause the wifi/radio module to be cut off.

im not sure how u guyz did it...
because of this issue, even im using neutral i do not dare to put all high powered devices on L1... including ceiling fan/motorized/spotlight, etc etc

sorry i cant answer this...
my practice is to avoid sudden high power pull on L1.
this is just to protect the wifi/radio module that sharing the power with L1.

basically if u r using neutral on the switch, u should be safe.
but if possible, i would like to avoid this scenario. just me...

as for ceiling fan or any other motorized device...
it did pull massive power during starting time.
tat why aircon use inverter motor to avoid start stop in between.

water heater and aircon are high power devices,
it didnt use toggle to flip the switch.

it need to use relay for switching.

mean it need neutral by default...

need review in this cctv options
1. buy nvr with 8ports poe
2. buy 8ports poe switch + own nas server + free cctv aps

the problem is my nas is only dual core 1.5ghz, 4gb ram
the advantages is, it use only 15watts and in future can add coraltpu

other than frigate, so u know any other local nvr?
currently i just wanted to start small... especially low power consumption.
will most likely buy 8x 4-5mb camera,
but will only record it as 720p 15fps h265.
stupid reason for having too many camera 🫣

dont expect to save alot of power,
the real killer power consumption is from the heater... not from the dc pump.

cool, let me check.thanx

ya my contractor have to hack the wall deeper.
still the same case.
just when screw to the wall, hv to use longer screw.

does anyone know what board is this?
it is mount below the alarm box.

normal smart switch can only support 2A to 3A per point.
u need a proper switch capable at least 20A for aircond.

I did saw some ppl use the power socket with smart switch,
those smart power plug have max of 16A, barely enuf...

quote from internet...

wow 👍🏻

i didnt know this, anyway i just use normal 20A switch without smart. haha
coz sonoff didnt have 20A smart switch... hopefully they release it in the future.

i dont think i want this meter + switch
coz the control will be at the db box 😅
prefer more conventional way where the switch is located at the room itself

my 2cents
1. totally agreed one the neutral cable, u will not regret it. ☺️
2. as for network cabling, it is very important... more important than ur mesh wifi. U only need mesh wifi if you didnt pull network cable.
The wifi roaming is depend on your clients not AP (dont use d-link, some of their switch didnt support roaming protocol)
3. As for network cable, pls choose CAT6, no need CAT6A or above unless u r loaded. If you wish to have PoE for cctv camera, make sure the cable is 23AWG and the keystone is also supporting 23AWG.
if u use 24AWG, the power will reduced as distance increase.
4. dont choose cheap wifi ap, if u have too many IoT devices that use wifi, u will cry (zigbee is okay). Can considered enterprise grade ap even if u dont have money. hahaha
5. The power socket, mayb u want to invest the power socket that come with usb TYPE B + TYPE C.
6. If u r not using HomeAssistant, use only 1 brand for cloud app.
Imagine u have light switch, smart door, curtain, etc all using different brand. (tips u can use alexa/google home for integration... but it still troublesome)

f***ed!!! u all use sfp module for ur home network?
might as well get fiber module, 40gbps... hahaha
worth every penny 😤

i think im going to develop heart atrack every morning seeing those figure. ended up i be using the dc ceiling fan only...
