Sonoff - flash with ESPEasy - working with usb, but not mains

[fandew]

Hello,
I've got some issues with my sonoff.
I successfully flashed two of them with ESPEasy. (build 120)
I then configured them while connected to the USB TTL/FTDI.
WIFI to GPIO13 so that green led light to wifi activity.
gave them the mqtt broker address and all.
ping working correctly.

But when I disconnect usb and connect them to main ( without the USB of course), I don't know why it does not work.
after around 45s to 1min, the led light up, but it's not connected to my network.

I've this problem with all the sonoff i've configured.

I've looked everywhere but no one seems to have had this problem, so I dont know what I am doing wrong.

oh and if I connect them back to usb, it work again, and wifi is connected in around 5 to 10s.

Thank you.

ive never configured them via an ftdi so i can't speak for that. how about you narrow it down a little by reflashing one of them. then configure one in steps. for example
reflash
configure wifi so it connects and you can ping it
reboot wait a few min does it do it?
configure mqtt
reboot wait a min
configure led wait a few
and so on. just trying to eliminate all the variables. i am going to just take a guess and its something to do with the LED

I have up to 10 Sonoffs in use with no issue so far. We speak from this Sonoff...? Have you checked the voltage of 3.3V of the power supply?

We can not help you without any infos about your configuration. Are you on firmware 2.0.0? Have you studied the wiki? All we don't know. We are no prophets....

Like I posted also elsewhere here on this forum today:

In the Tasmota issues some reported something similar: https://github.com/arendst/Sonoff-Tasmo ... -342000029
There was suggested to add an extra 400V 1nF capacitor.

Does that photo match your Sonoff's?
