Try change screw. Bigger a bit. Tape will not have good contact. Can generate heat.

I think it will not work with fan. Note that the ceiling fan or any induction motor that runs on single phase supply require capacitor to make it turn. The smart switch without N wire connection usually need to put a capacitor between L and N. this will change the capacitance value of the fan as well and probably offset the phase to make the fan turn.

Not familiar with Broadlink. Do you have a capacitor installed to make the smart switch work?

I think the first one was from a company called Augreener. It even has FCC ID for use in the US. However, now many copies of the technology as you can find in Shopee

I guess we follow UK or stick to old wiring. It reduces cost. If require N wire at switch box then, you need additional wire pulled to the switch. Therefore, you would have 4 wires at the switch connection since you would be looping the N wire at the switch level instead on ceiling.

I don't think this is correct. The bypass capacitor purpose is to leak more current from L wire across load to deliver to the switch. You can never do that with bypass capacitor in the switch itself because the load is up there on the ceiling.

I guess those claiming no need to have bypass capacitor is just because they believe the small average current leak by load itself is enough to drive their circuitry in the switch.

The frequency used by the radar in this case is 3.181GHz. Will not interfere with WiFi.

Both IR and radar detect presence of human by movement. Most IR sensor detect heat grid change in sensor to trigger, not just heat alone. So, if no movement, it will also shut down like radar. Same operation but just different methods.

I get confused here. Why N has anything to do with zigbee being a router or repeater in first place. The connection is wireless. Having N connection or not only related to how the zigbee device is powered.

Maybe they are playing with words. The 3 month is just the power retained in battery in OFF condition

Yes. 20A double pole switch sure got N. However, if your house 3 phase wiring, N can be separated too for each phase, Pairing L to different phase may trip main RCD if your house use one.

You meant unlock using phone? Why make it difficult? Thumbprint is difficult?

I saw grill and main door use small QR Code like like 20x20cm "sticker". Well it is more like that magnet sticker you put on fridge but much thinner. I guess this can be put in wallet and become like RFID or TnG to open the door.

What air-con has only two pins?

Hold on. I get confused here. All wall sockets in Malaysia have 3 holes. You meant all your air-con has no Earth connection. Are you in Malaysia?

Yes it is hidden in this case. Looks like you have faux wall.

Oh I forgot to tell that the higher power air-con may have wire connected directly to starter, but it looks to me yours is no more that 2hp

I think Tuya is just provide smart platform that provide solution for house automation mostly. Many brand is using Tuya platform. It can be any brand. So, I wouldn't say rebadged.

Should be possible but you need to have electronics knowledge I suppose.

Can use any bi-polar capacitor like poly polypropylene or mica

The picture you've shown has value 5.6nF which is too small. Not enough current passes through thus still blinking. I cannot recall but actually depends on the switch itself.

More accurately, WiFi, Zigbee, Z-Wave, BT are are just communication mediums

I'd suggest just replace the whole thing. You can easily find the the exact hole size. If you just use an LED bulb and use he existing fixture, the light is really has narrow beam straight down. The complete LED version is not only lighter but the LEDs are mounted close to surface making it light beam even wider. You get mote brightness than with that old type fixture, unless that is not what you prefer.
