So, your house is 3 phase wiring? Your house has 3 separate RCCD? If one big one with linked switch lever, maybe it is using common N line?

Buy good tape like 3M. Cheap DIY china one may drop over time.

Good placement would be an area where you think smoke will accumulate first. For 2 storey house, smoke tend to go up through staircase. So, the ceiling at the top center of the staircase is probably the best location. By probably 2 unit. One for kitchen ceiling and one hall area or location I mentioned. The wall at at kitchen entrance/opening will block the smoke from going to other space like hall until more smoke and this is late already

Yes branded one many fakes. If significantly cheaper than other shop, then suspicious.

Inside the room already late. Door closed and the smoke already thick outside your room

So. put in each room Good business for Xiaomi

You forget to close the gate but what if you forget to even check the CCTV. Probably by the time you check CCTV, it is too late already.

Why not make it auto close after certain period but of course with sensor to check nothing obstructing first. This I would say smart gate

First picture shows that the GND are connected to 2 copper bars. The reason for two bars is likely because they don't have longer bar for all GND wire in a single bar. There will be wire joining the two bar, I'm sure

The 2nd picture shows that the N wires are separated into 3 separate bars. Looks like the N are going to be separated but it can't be sure just as yet. Maybe they are going into 1 master 4 pole RCCB or 3 separate 2-pole RCCB. If 3 x 2-pole RCCB, then N has to follow phase. Why not just call developer or the guy in charge of the project and ask. The person can tell you for sure.

Automatically moves the plant pot outside in the morning and inside at night

I bought most of the required tubing, connector, etc. for more than a year or two and still in my store room

Why didn't you just buy the standard timer valve plenty out there? Just because you want to control using your phone?

Just need install sensor to detect soil moisture.

Agree. Timer is not cheap. I was thinking just to control the solenoid valve using moisture sensor. Sensor is cheap or can just make simple one..

Well, the idea is running more than a year

Voice control no need internet. The instruction is:

"Please switch off the light, honey"

The worst is just that the switch stop to work. This is quite normal in design. Computer simulation is not perfect and the part is not perfect too. The component selection is normally just enough to meet to meet circuit requirement just to save 0.01 sen

Recall is even worse in vehicle. Defect discovered after probably after accident happened 7 to 10 years down the line and manufacturers will admit probably a year after investigation

Rechargeable battery will not last as long as regular non-rechargeable one. There is non as far as I know. Furthermore, the rechargeable battery operable length gets shorter and shorter. It is more nuisance recharging it than using normal battery.

Actually, it is not about minimum load but minimum leak current that flow through load (bulb or whatever) in off condition. The LED has very load leak current, thus could not provide enough power to the switch circuitry. Therefore, the switch is provided with capacitor normally about 0.1uF to be connected parallel to the load (LED bulb in this case). The capacitor will leak the AC current to the switch to ensure the switch works as it should.

So, if you have flickering problem, you need to install the capacitor. Otherwise, there is no need to.

This type of DIY type can be found is electronic/electrical part shop like Jalan Pasar. Maybe can go to shop that repair TV, They do sell this kind of thing too

I think it is what you looking for. Don't get confused with inching term used. It is actually like momentary push button switch if not mistaken. I believe this is what you need. It will perform like door bell or gate switch

Depends on house wiring. You can just try. If it works, it works. Otherwise, it will trip the MCB. Then probably you have 3 phase with 3 separate RCD breaker. Then you need to find the N from the same phase.

Yes. Can tap N from any point
