I think you weren't talking about socket but switch, right?

Why need to control everything from phone. If cannot find your phone or phone malfunction, then no coffee

You can just buy smart module to control the light, can't you?

Probably just advertise and not sold here. Typical Philips and many big companies style

Order locally online. Goods ship from China

You can just Google Smart Glass Malaysia. I think it is not cheap

Power consumption would be just like your TV in stand-by mode basically, or even your air-cond waiting for IR signal command.

Plenty of image if IR Blaster if you Google. Yes, IR will be block by wall but Blaster can be controlled from your phone which will trigger blaster located anywhere in place where you have devices or appliances controlled by IR.

No, I don;t have one

Anyway, the LED color is not really consistent. Just like colored tiles used in bathroom for example. Different batch may have slightly different tint to its color. Same as RGB. To be able to create a true white color, you need same amount of intensity of RGB color which may not be the case and due to the tint mentioned the result is not consistant.

This is one of the main reason between general LED light and professional grade LED light. They measure color data like color coordinates, color temperature, color rendering index (CRI), color purity or color deviation.

Whoever want to control my house light from outside must be really sick

In theory yes, but it is just house distance. I found my 5GHz covers my whole house just fine with at least connection at 200Mbps on single WiFi router.

Yes, I've never seen any device that support only 5GHz but both.

Is that the air cond start stop switch? Then normally has N wire

I have come across switches that can be used as two way in Shopee before. Did not bookmark it. One side is RF type with battery and the other side just need to replace the existing switch.

Most smart switch has relay that made contact when powered on

Since it is called motion sensor, then it only detect motion. Sadly also, many infrared sensor is actually motion sensor. These are PIR sensor (Passive Infrared Sensor) where it has 2 IR sensor side by side. Once there is movement, the difference in measurement between the two sensor will trigger the switch which means movement sensor, not detecting body heat.

You need to get an Active Infrared Sensor which detect presence of infrared like body heat.

If search Shoppe anything related to IR will come up and even those said Presence Sensor or even Active is actually not actually what they are.

No, I have none to suggest even though I also want one. I have yet to actively look for it. The active one is not dirt cheap like PIR sensor I think

Too brief and no specification at all

I think it is cheap also since there is sensor specific for this available now. If you are electronics DIY kind of guy, this will do I think

Will try to look for off shelves maybe later

This probably the same product that your link refers to. Not cheap though

It said human physiological parameter but not sure how sensitive it is. This is based on mmwave.

The 2nd link is the raw sensor itself i.e. the component used in 1st link project. You cannot use part in link 2 as complete device
