As long as you get the non neutral version

I know this sound stupid, I need to use insulating tape to insulate the neutral wire, right?

That's what I did for my ac's at home since they're all older models with no wifi support, never thought about hooking up the ir receiver to the ac pcb buntil i saw that video.
No need to power the esp from another plug or ac status not in sync because someone using the remote

I do have like a really old alarm system, but I abandon it anyway since I've already installed all the aqara sensors when i started.

Better to be safe,
Btw, did you do a renovation to pull all the neutral wires or has it always come with the house?

I wasn't sure. But I think those neutral wires came together when renovation 10 years ago.

Wow... 10 years ago already pull neutral wire? You sure it is not looping wire which is no longer in use?

Good question. Don't think it's wire that no longer in use because still connected to current switch.

There’s the extra black cable but you said it’s connected to the switch? Connected to where? The Live portion?

Or is this for the 20A switches?

looking to convert my new house to use smart home system. can advise where can i start with ? What brands are recommended interm of value for money and support if needed ?

It look like this, that's why I thought it is neutral wire.

This is a 2 gang switch? Yellow and red goes to light/fan?
Live is blue? Then yellow is it loop to another switch?

What type of switch is that? Got more angles?

Tuya, they’ve got their hands on pretty much any smart device out there and inexpensive

I got no idea, I shall take more photos from different angle and ask again.

It's a 2 gang wall switch.

For me the least headache is going all with Aqara stuff.

Yes, I’m using Aqara since Dec’22. So far so good, only got one switch not sure why it randomly kept flashing red. Had to reset and pair again.

i am planning to use the Aqara system

question now is for the 20A switch Tuya, can that one be connected to Aqara Hub or i need to add another zigbee hub ?

Presently no, at least until tuya add thread/matter support (probably another year or so)

For the 20a
Use any aqara switch + contactor -> ac/water heater

Like Max does

There's no Neutral on that switch box.
in common wiring (local here/Malaysia) practice, coloured cable is Live usually. Neutral will be black.

all the 'looping' in one terminal is Live source from supply DB or from another looping in another switch nearby.

Thank you for clarification. Can I loop with Aqara Smart switch?
