Hello sifus, I would like to check if EVA or reTouch brand smart switches are ok? Specifically the no neutral/no capacitor kind.

Salesperson tells me that no neutral or capacitor is required, which is counter to my knowledge of smart systems in general (need neutral/capacitor to ensure steady small current in switch or circuit).

Can anyone verify whether that is possible?

I have super newbie questions 🙇‍♂️ would like to ask:

1) Are smart switches able to wire for 2 way, specifically smart switch for water heater? One of the smart switch vendors I spoke to suggested that I use app scene/automation function to mimic 2 way switch function instead, I'm not sure if this is recommended...

2) From my understanding, most smart switches are not compatible with DC fans. Would like to ask anyone's experience, do IR/RF blasters work well with remote controlled KDK fans?

Thank you, this was the clarification I needed 🙇‍♂️ maybe because I'm not very fluent in Chinese so the smart home vendor I spoke to didn't seem to understand my concerns about 2-way switch.

Yes, just on off for the fan, I already have existing basic system of smart bulbs and considering add RF/IR blaster (built into ZigBee hub) but I was finally considering doing proper renovation to add smart switches for further control over house fixtures. Just that my fans and lights are currently sharing gang switch and I don't want to hack another hole just to have a dedicated fan on/off point

Yes, I've seen some two way smart light switches, wondering if there are any 20A rated smart switches can also be wired the same.

Oh I didn't think of this, thank you!

Although I think what I remember from research in past is that such relays are for low ampere (10A), are there models meant for high-power appliances like air conditioner and water heater?
