Wifi Wall Switch WITHOUT TOUCH (1,2 or 3 Gang)

[tyjtyj (Justin T.)]

The one i share dont work for EU?

[orange-assistant (the real one)]

Finally, they look like EU ones. They also name tuya app which makes the possibility quite high that a esp8266 is inside. Just the price is a bit high… but I need to tell I’m tempted…

The other possibility way to go nowaday is to keep the old/normal/present switches and just add a shelly or any other brand with a switch input behind the wall mounted switch.

But for new installations integrated is always good!

If someone could share findings with the device @tyjtyj linked - would be great!

@nickrout

I meant the light switch, but I cannot find the eu physical switches now.

I searched hard the other day and came to the conclusion that zemismart does not have physical wall mounted switches with eu type. Please proof me wrong with a link

[tyjtyj (Justin T.)]

This page say it can be flash to tasmota via tuya convert

DS-102 3 Gang Switch Template for Tasmota

Hope that give you some confident.

I think you are right, sorry for the noise.

[orange-assistant (the real one)]

Do you know (or someone else) by accident how this device looks from the inside? A the important pins available to flash custom firmware (as the bug tuya convert uses is fixed nowadays more and more… even with ota!)

Picture would be also fine for sure

EDIT - sorry, just realised that you were asking about another switch. Ignore this post

Yes, I posted some pics more than a year ago, when I installed a few of these. They are still working well.

What Wall Switch Options are there?

Hello @Bobby_Nobble I had another of the Chinese switches arrive yesterday, my third. Having gone through the bother of flashing and configuring it, it was only at the last stage of fitting it to the wall that I found that the screws fixing the board to the case had been omitted at manufacture stage. But at least this gives me the chance to post an image of the business side of the board for you. This is a 1-switch and - as you can see - has only one relay. It’s not obvious to me whether the o…

PS I flashed mine using SonOTA

@PianSom - Can you provide a link for the flash method you used? I just got a three gang version of the Zemismart and can’t discover the device when going thru the OTA flash process. I was following the Tuya convert process with no success.

[stevemann (Stephen Mann (YAML-challenged))]

What’s wrong with touch?

[PianSom]

@scp028

mirko/SonOTA

I’ll be interested to hear if this works on your hardware

[scp028 (scp)]

@PianSom - TY, going to try it tonight. Do you have a link to a tutorial on the soldering option if OTA doesn’t work by any chance

[PianSom]

@scp028 - well, I guess that rather depends on the hardware you are using!

FWIW I have found that I can usually get away without soldering just by holding pins in place for the short period that the first flash takes. Helps to have a friend handy to push keyboard buttons

[orange-assistant (the real one)]

Touch is not intuitive or blind usable. It lacks basic physical feedback and it’s a productivity killer. In my studies you will need an average of minimum double the time doing something with touch wall switch than you will need with a ordinary latching or non latching wall switch with haptic feedback.

So in general it’s just the opposite of smart.

[stevemann (Stephen Mann (YAML-challenged))]

Not to be insensitive, but why would a blind person need a light switch?
I can see why it would slow one down because, for example on one of my touch switches, I hesitate to determine if the switch did what I want. With a tactile switch I don’t have to slow down as I exit a room to know that I toggled the switch. But you gave me an idea. Since I made the switch using an ESP8266-01, I have one more GPIO that could go to a haptic buzzer, like in the cell phone.

@stevemann

Maybe it is a fan switch, or a heater switch, or a waste disposal switch.

[tribut (Felix Eckhofer)]

So I bought some DS102 switches (no touch, with physical buttons, EU) that @tyjtyj already mentioned above. Unfortunately, tuya-convert appears not to work, so I will have to try and flash them the old-fashioned-way. Here are some pictures:

As you can see, there is a small board on top with the ESP8266 (TYWE3S) on it. GND and 3.3V are easily accessible from the socket on the bottom. TX and RX are on the bottom-right of the chip on the pic above. No sockets, but should be easy enough to wire.

I will report back on my success (hopefully) when I find the time.

[orange-assistant (the real one)]

Tight! Thank’s a lot for sharing your findings!

Please provide more pictures when/while you flashed it!

[tribut (Felix Eckhofer)]

No surprises when flashing. Because I have no idea how to safely solder stuff directly on the chip, I just attached the 3V/GND on the back and held the TX/RX in place using my fingers. Worked without problems:

Here is another guide to flashing these, if you want to see more pictures: https://www.hackster.io/michael_zanetti/smartlife-tuya-wifi-light-switch-with-tasmota-and-nymea-09a7a6

Any finally, this is my esphome config for the 1-gang version: https://gist.github.com/tribut/24da88affbf0d57a6ad143edcf6b53d0

Have fun!

Smart solder free flashing! How did you enter the flash mode of the esp chip - by accident using the button in the middle?

[tribut (Felix Eckhofer)]

Ah sorry - I forgot. No, the button is connected to GPIO3. You have to connect GPIO0 manually to ground while plugging in (it’s the fifth pin from the right on the same side as RX/TX - for images see Sonoff Wiki or Hackster.io).

I used the same method: Just hold a jumper wire in place. You don’t need to keep it there, a few seconds during startup is enough.
