Sonoff Touch Assembly & Installation: Troubleshoot Connection, Flickering Light Issues

Hello all.
I am asking for a hint / help in connecting the Sonoff Touch switch.

Unfortunately, I do not know the scheme of your installation.

I am submitting a photo as I have a regular switch connected. As I dismantled the switch, the current was in the black lead.

After connecting Sonoff Touch (black L in, blue N in) I found the switch in their application without any problem. The problem is that if the switch is turned off, the lamp lights up, but let's say it's 40%. When I turn on the light with this switch, it is brighter. In addition, there is a problem with the flickering of light (irregularly lighter-darker).

Is there a chance to connect Sonoff Touch seamlessly with me?

Probably there is no neutral switch in the box so you will not connect sonoff
Sonoff Touch requires an uninterrupted L, N and a vein for the light source.
So, for example, a twilight switch or motion sensor.
If your installation (skip the fact of the color used - there was a thousand on this topic) to the switch goes from the junction box it is not at the neutral switch, and it is necessary for this switch to work. You have connected it in a row with a source of light and that's why you have such problems.
The only advice:
Get to the junction box and bring it neutral to the switch.
Once you've done it, make sure the veins are in the right color. So neutral blue, phase - any except blue and yellow-green. Yellow-green alone can not be an active conductor.

Good morning, I refresh the topic. I am a total layman in electricity, but I do not have a leitter in which I trust;
I would like to connect Sonoff Touch T2.
In my box, the blue (N) cables are all fastened in a plastic connector. Green-yellow cables (ground) are also stapled together in plastic.
Brown cables go to the switch.
Brown cables I know how to connect to Sonoff. The question is about the blue cable. Do I disconnect from the main blue (going from below to the can) and connect it to Sonoff? ALe then the other blue ones will not touch it.
Should an additional blue join the plastic fitting and pull it directly to the sonoff?
I know, I know that people who have no idea of the current should not do such things.
Thank you in advance for constructive responses.

Yes. Brown that goes to the bulb at the sonof output

I do not think we understand each other. Brown are to enter the L outlet.
I am asking about BLUE, which I do not have loose and I have to either remove it from the connector or add an additional blue to the connector and pull it up to Sonoff.

Before joining the blue one, check first if it really is N
And do not disconnect others, just add an extra to sonoff. It's best to measure the meter whether you have a full 230V voltage between this blue and phase.

After all, I wrote that you're good at combining.

Yes. But the one on which there is always the phase at the entrance, and the one who goes to the light bulb to leave.

Hello
I have an identical problem with flashing light and there is no way to turn off the light

in the can I have only 2 cables (current and zero) or to connect the sonoff I can connect the missing cable from the socket that is next to it (there is also 2 cables in the socket) ??
I can not connect directly to the box because the main can is on the ceiling so forging in the ceiling does not enter into the game


The first time I have contact with this type of switch

I do not know if I understand correctly but additionally there must be only massage ??
