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

Hardware
41

You also have a esphome sketch for the 3-gang version by accident?

I wonder how they managed to add 3 relays, 3 buttons and 3 leds (in all it would need 9 gpios in my world)? Is there any limitation regarding the leds (forced binded to a relay for example?). My plans is to have leds independent from the relays but rather show the state from a other device from home assistant (and also to control it with the push button…). Any thoughts on this?

The 1-gang version (I can see in your sketch) has one gpio for each relay, button and led :+1:

For 2-gang I can see here (SmartLife/Tuya WiFi light switch with Tasmota and nymea - Hackster.io) that relays, buttons and leds are also separated:

GPIO0  -> None (0)
GPIO1  -> Led2i (57)
GPIO2  -> None (0)
GPIO3  -> Button1 (17)
GPIO4  -> Relay2 (22)
GPIO5  -> Button2 (18)
GPIO12 -> None(0)
GPIO13 -> Relay1 (21)
GPIO14 -> Led1i (56)
GPIO15 -> None (0)
GPIO16 -> None (0)

Just need conformation that it’s the same for 3-gang @tribut maybe? :blush:

Sure, here is an ESPHome config for the 3-Gang-Version: https://gist.github.com/tribut/ddde2ef1e2fa3919c50c4ab9c03e7056

I actually use some buttons on these for triggering devices not connected to any of the three relays (which are disabled in ESPHome) and update the LEDs accordingly from HA. When declaring the LEDs using the monochromatic platform, ESPHome by default even adds a nice fade effect, which works really well.

I think this is the device I waited for. Bundled with esphome this is a powerful thing! :rocket:

Actually a shelly or sonoff mini get’s really dumb beside this one (no led’s, no easy way for triggering multiple actions with the button like to keep it pressed for 3 seconds…)

Beside that it can be programmed fail-safe (still works locally when no network available for example).

Also with the 3 leds there is nice things to do. If connection to home assistant is not present the leds could ‘walk’ from left to right or so to have a visible feedback :stuck_out_tongue_closed_eyes:

It’s actually 4 LEDs - 3 blue LEDs and an additional red LED (in the middle). If you look at my esphome config, the red LED is currently used as status LED, so the device will blink red on connectivity problems.

I really like these switches. Sure, the buttons feel like mouse buttons, not what you are expecting from “normal” wall mount switches at first. And installation was a bit fiddly for me - when you have barely enough room in the wall you can’t just tighten the screws - the case gets bent the tiniest bit and buttons start to malfunction. But once properly installed they seem to be reliable (for the few weeks I owned them anyway) and having actual buttons instead of touch surfaces means children can operate them easily and you can find them at night without problems.

For those still looking. I found zemismart eu/uk version work with tuya convert.
#Aliexpress 40%OFF | Zemismart WiFi Wall Push Switch Alexa Google Home Tuya Light switches Three Gangs Two Gangs One Gang Physical Button

Install and flashed tasmota. Works for few week now.

Nice! thnx for the tip, instantly ordered a couple.

47

Use this template when you got it…

I like zemismart cause it got white light instead of green for other similar product.

48

I found another option here, anyone bought one to flash ? I tired of trying new things

MOES WiFi Smart Wall Light Switch RF433 Push Button

Please post if these work with tuya-convert.

50

Yes I can confirm these work with tuya convert. Did a successful flash last week.

51

Great ! No touch, tasmota + rf433. Ideal. I will order some.

52

Not sure how these work together with rf433 to be honest.

53

@francisp Oke, I totally misread the thread, I thought you were referring to the Zemismart switches.

@tyjtyj were you able to control the leds on the zemismart switches? I see that the blue leds are connected tot the relays and white is always on.

54

Only able to control wifi led. You can check zemismart templates. Those led are linked.

55

Let us know if u order Moe’s. I chat with vendor they mention it is EU but others are selling as UK too.
Let us know the switch depth and if tuya convert works.

Similar to the Zemismarts there seems to be a version from Lerlink (sometimes sold as Losonho):

I now have several of these switches working here and you get a big range of models, i.e. 1-, 2- and 3-gang and since a while ago there is also a version that requires no neutral line.

On Aliexpress i got them from here:
http://s.click.aliexpress.com/e/olUdOPzI

And yes, they worked with Tuya-Convert flawless (can’t remember the version, one of the newer ones i think). After initially flashing Tasmota for testing the gpios i switched to ESPHome, which by the way has a way better reaction time with the buttons and switching the relays. Maybe that was a configuration problem in Tasmota, just used it out of the box. But with Tasmota i had a very noticable delay (maybe 0.3-0.5s), ESPHome switches intantly.

57

To removed the delay, setoption13 1 on tasmota.

Losonho model, have you tried model without neutral? Does it flash able with tasmota?

I like zemismart white light, none of other brand have it.

58

Thx for the info =)

And no, i have the ones with neutral since i have neutral wires in my flat. I couldn’t understand your second question. The Losonho models can be flashed with Tuya-Convert. And then it’s up to you, what to flash. I flashed Tasmota initially, because with Tasmota it is very comfortable to find out the gpio pinout. And once i knew the pinout i changed to ESPHome.

The color of the light was not my first concern. In every switch the normal background lights (the green ones) are deactivated. Sadly the red leds are tied to the relays and can’t be controlled seperately.

59

Some no neutral switch used different chip thus cannot be flash tasmota.

Really thanks for the info sharing… now I have more choice.

60

Thnx for Sharing, good to see There are more EU friendly switches coming on the market. Could you share the esphome setup for the switches?

To add to the list of possible switches: I found these zigbee switches which are also Made by lerlink. The thing i liked about these switches is that they only use the leds to show status of the relay, I feel like the “always on” leds are a bit to bright During night time.
