Sonoff TX smart wall switch 

Thanks. I think I need to do "what's new in eWelink" video.

Wait, the others are correct. You need a neutral wire for these switches to work. I have two wires only because I did not wire up the bulb to the output. So you definitely need 3 wires for a 1 gang switch: live coming from the switchboard, switched live going to the light, and neutral. But Sonoff actually has a single live wire version, which does not need the third neutral wire: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xckLtFYS77I.html. So you need that version, otherwise it will not work.

@@csongorvarga I have 2 wires for the 1 gang switch. Switched live going to the switch and a neutral, no 2nd live wire. Will this work?

Yes and no. This TX switch also needs mains power to operate. It needs to be connected to both the live and neutral wire. Older switch boxes usually have only the live wire in the wall box where your old switch is (only black or only brown wires - but varies by geography). So if you do not have a neutral wire, it will not work. In such cases that is still and option, because Sonoff also have a switch which looks like this, but it is called "Single Live Wire". That does not need that neutral wire.

I am pretty sure it does. Just need to wait until somebody publishes the details, like were the various connectors are.

@@csongorvarga I saw a video from Dr. Zzz that he flash it with Tasmota. My new question is if you could control self-locking and inching together, I think you cannot by using eWeLink, but do you know if it is possible by using Tasmota firmware through Node Red. I just ordered one switch yesterday to test it but it will take time for the arrival.

Flash it with esphome

Yes, it works the same way for me. It says on the bottom of the interlock screen that the inching will be disabled. It is not ideal. You can only rely on the limit switch in your curtain motor to switch itself off. The only option I can recommend is disable interlock, enable inching, and set up two scenes: scene #1: when gang 1 turns on, turn off gang 2. Scene #2: when gang 2 turns on, turn off gang 1. Since this is done by scene, there is a small delay and it only works if you internet is working.

Yeah, I am not aware of any way to change that. Unless you start modifying the board, but I would not know where to start.

Thanks. If the wifi is off, the button still works. That case it acts like a regular wall switch. Inching is an auto-off function. E.g. you can set to 15 minutes and the it will automatically turn off after 15 minutes.

@@csongorvarga. Okay got it thanks for replying me

Yes, in the settings there is an option called "Power on State" and there there is a "Last state" option. So it can return to the last state after a power outage.

The neutral is not switched, this is why there is no out. Only the live goes in and out. The neutral can go directly to the lamp and the switch.

Typically these devices consume around 1W each. But I have not measure consumption over a longer period.

Yes, you can install this, just power it to the mains. It will not switch anything, physically, but in the device settings you can group this device with the Sonoff mini. This way when you switch the TX, the mini will switch as well.

@@csongorvarga thanks man!!!

@@csongorvarga Does this work also with sonoff R2? (f.i. sonoff r2 + sonoff tx)?

@@andrejsersen59 I did not see if there is any device it would not work. But if the group is not available, you can also set up a scene to do the same. And that definitely works for all models.

In terms of functionality they are the same. So it is pretty much looks. T2 series have models which have optional RF switch. That could be useful.

I did not measure this, I measured other Sonoff devices and it was 1W. Probably below 1W but the device does not measure such low power. So it is less that even a small bulb, when you have a few dozen of these around the house, it adds up.

I have a separate video on that. Using scenes in eWeLink.

Yes, they are. This is why I am personally not a big fan of touch switches.

So at Night your screen is brighter and on sunny day you got it dimmer?

There is an indent on the bottom of the bezel. Put a flat screwdriver in there, twist and the bezel pops off.

Yes, there is a group function in the settings, and you can group multiple switches together for two way or three way switching.

@@csongorvarga thanks a lot

Szia, nem lehet állítani. Lehet valami rossz a forrasztásban ezért halványabb az egyik. Ha lepattintod az előlapot akkor láthatod a LEDeket. Esetleg ott megpróbálhatsz valami intézni vele. Mondjuk ami túl világos arra filctollal rászinezni egy kicsit.

not sure if anyone gives a damn but if you are bored like me during the covid times then you can watch pretty much all of the latest movies on Instaflixxer. I've been streaming with my girlfriend for the last weeks :)

@Harrison Westley Yup, I've been using Instaflixxer for months myself =)

The postman was here 10 mintues ago and delivered the review sample for me :) So a new video is coming.

@@csongorvarga Haha.

Not with the standard firmware. And I don't know if there is option to make it compatible with custom firmware.

No, but there are guides on the internet how you can flash the firmware on the device to Tasmota and than you can control it locally. You will loose the eWeLink access and there is no way going back.

@@csongorvarga Thanks a lot! I successfully flashed tasmota via raspberry

No, this only and on/off switch. Cool profile logo :)

Dam really wanted a Dimmer on it that would be cool to control a Dimmer on my phone

If you flash it to Tasmota.

What do you mean? There is a Scene button on the lower part of the screen and after that plus button on the top right. Or where did you get stuck?
