Who'd want to spend so much just to look at the power usage. If the device can guarantee reduce power usage by even 10% many would buy

It should be able to display usage on app. It is more flexible this way. Our tariff calculation are segregated into 3 tiers for different rates. So, more practical to do through apps on the phone than device firmware to check current billing status wirelessly I believe. Use Local LAN is more practical for reading.

Yes, but rate may change from time to time. It is more convenient for end user if it is like apps update than to key in new data in unit

Not blinking at all means either no power coming in or faulty unit, I might say. Otherwise it will blink if no connection.

Maybe this will help:

With many companies producing and selling smart touch switches that can be controlled using WiFi from anywhere, does each of these companies set-up their own server to provide services for free? Anyone has any idea on this?

Thanks for info

Buy something universal like this. Easier to find

No reason to sell socket for China or Australia standard in Malaysia. You can easily order from Alibaba instead. I would just change the plug to local type.

Order from Alibaba would be still fast enough.

I believe the only way to buy in Malaysia is the universal type. I've check the manufacturer website. the universal one does support 16A. The difference is only that the earth blade is wider and longer.

Legrand is branded name. Even have office in Malaysia I believe, just like Schneider.

Well, I found it common in many electrical shops that sell electrical stuffs for contractors. There, you will find it much cheaper than any shop that sell general things.

The list price is crazy

I think plug is different story already

State what do you want to do/achieve or control for best recommendation.

I do not know if there is any branded smart switch that hooks to existing wiring (I mean at wall switch) to simulate multiple wiring. There are many from generic brands that do this, like flick wall switch once will light up one point and flick the switch twice will light up another point, etc. There is also option for using remote. The receiving unit need to be installed at light points on ceiling. Branching of light points is at the ceiling, on the receiver.

For branded smart switch, the best option is to buy a battery operated switch that will act as transmitter to control the receiver located at the light point. It work like the one above but instead of separate remote control, each switch controls one light point. the switch itself is a remote transmitter (battery operated) that can be mount on the wall anywhere you like without hacking the wall.

I think the Samsung SmartThings are multi platform, support Z-Wave, Zigbee and IP-based devices. However, like you said frequencies are different from country to county. Z-Wave band in Singapore is same as UK but different from Malaysia. Zigbee I think the same

Read some community discussion here:

I'm in agreement with your on this. The Reference Designation on the PCB is the step down voltage from the multi-winding output. It is the AC voltages. One output is 24V which probably rectified by that full bridge rectifier (big square with hole in center. The other output is probably the 12V rectified by the two diodes (half bridge rectifier).

Imagine the internet is down like it usually did. Everybody is sitting in front of the gate

I wonder why need to tinker inside that control box when you can just replace the wall gate switch with remote one
