Did I understand this correctly?

Hardware: Install the Aqara wireless relay at the ceiling light and pair it with the Aqara wireless switch so that I can control the light manually or with voice.
Software: Use Home Assistant or OpenHAB to bridge between GH and the hardware since GH does not directly support the hardware.
You need another piece of hardware as the wireless switch can't pair directly with the relay. Xiaomi Mijia gateway is recommended over Aqara gateway due to the LAN mode support you need for HA/openHAB to talk to the gateway. Another route: use zigbee2mqtt CC2531 dongle. Some of us migrated from the Xiaomi gateway to zigbee2mqtt as this is compatible to a growing list of Zigbee device and actively developed. Xiaomi's one only supports their own ecosystem.

Looks like I'll need to get my hands on a set of gateway/relay/switch and experiment from there!

Is there a consensus on the most "reliable" smart switch yet? I'm looking at Sonoff T1 UK, but it seems it's not easy to buy this locally? I looking to buy something reliable with neutral.

U can buy from Aliexpress. Look for sellers with good ratings.

My non-neutral switches from Broadlink are still working well after more than 2 years. So far 2 of them kaput but I have tried successfully to claim for replacement within 1 year period which they honoured.

Lazada,Shopee,Qoo10, Taobao, Carousell, Aliexpress etc. Buy from physical brick and mortar store?? I highly doubt you can find one.

Buy from sellers with good ratings and reviews and good sales lor.

hi all, im interested in replacing a dumb switch with a wifi-enabled smart switch that needs a neutral line.

my understanding is that i need to pull a neutral line out to the switch outlet.

question is, can i tap the new neutral line from the light fixture end. connect it to this terminal connector together with the existing one.



fish it out from the conduit to the light switch outlet, and connect to the smart light switch?

is it the safe and right way to do so?
Can, i tapped from my wall plug nearby.


becomes

Hello, I hope someone can help me look at my photos of my old switch and see if it has neutral wires and how do I connect it to the Sonoff T1.I'm not sure how I'm unable to post photos here. Are you able to help me on that? It's a DIY project that I hope to do myself. Thanks!

if you are not familiar with electrical , i suggest you hire a electrician and learn from there.

The Sonoff T1 will require a neutral cable and you don't usually have it at your light switch. Your electrician will need to wire it for you.

Lastly , let's not forget neutral carry current as well and don't get your hair permed for no reason. It may be your time perming your hair

Exclamation CNC

CNC MACHINE HOBBYIST AND PRO

I am using...
CNC machine 3018
Software is gbrl

I want to cut specific hole (rectangular) on a PCB. Already have the dimension for the cut out. Are there any software which can simulate my PCB design and the cutting, so I may not need to do the coding?

Either way I love to hear your great idea!

A quick walk around the shops might prove valuable. I don't think buying such online will do you any great favor. Just take a walk...
