Re: lc technology ESP8266 realy x4 Problem
Can you give a schematic of the board?

Re: lc technology ESP8266 realy x4 Problem
I cannot see what chip is being used to control the relais.
They used an ESP-01 module, which only exposes a limited number of GPIO-pins.
So the SMD chip next to the green power socket must be doing something, but I don't see what chip it is.
This makes it really hard to tell what may be going on here.

Re: lc technology ESP8266 realy x4 Problem
I think it's a NUVOTON 8 bit 8051 compatible microcontroller
Re: lc technology ESP8266 realy x4 Problem
That's a microcontroller running its own program.
Without knowing what it is running, it is near impossible to tell you what's going on here without thorough investigation using a logic analyzer.

Suggestion ... start here:

Install APP "EspTouch_Demo" android version to configure wifi account and password for ESP-01 module on the first time of mode 2
30+ ESP units for production and test. Ranging from control of heating equipment, flow sensing, floor temp sensing, energy calculation, floor thermostat, water usage, to an interactive "fun box" for my grandson. Mainly Wemos D1.
Re: lc technology ESP8266 realy x4 Problem
It is a standard 4 channel Serial MCU controlled relay/switch, can be used with ESPEasy and P165 plugin. (If the NUVOTON has its standard program)

Re: lc technology ESP8266 realy x4 Problem
Hai hosam, have you fixed the problem, becase i have same thing here,
Im on mode 2 of relay modul, the board show the blue light, waiting wifi connection
But until now, i cant find hiw to fix it
I have pushed the switch mode and reset mode, but nothing

Re: lc technology ESP8266 realy x4 Problem
Check that switch is really working. In my case was the opposite. Never got the blue led, until I bypass the switch. Maybe yours is short circuit....

Re: lc technology ESP8266 realy x4 Problem
I think you need to reset it.
remove power
press the S2 button and keep pressed
add power to the module
and then do not press again the S1. I did this also accidentally once and hat the same pain as you
