Are there one or two types of Sonoff Basic?

Ah right thats good about IFTTT.
No i meant NodeMcu flasher.
thats the software you use to flash the firmware onto the sonoff instead of the ESPeasy

Can I flash that previous sonoff devices again??

I tried it with previous Sonoff device but flashing not work by this flasher.

Yeah you can flash them as many times as you want are you following the guide on the community and using the right firmware.
Have a look on there it has all the settings you need

good …

I follow the steps in readme file which that link you are send.(What is mean “GPIO0 MUST LOW.”)


if you have a guide file or video will be better.

I used the firmware which in this link:

Try following this guide

I tried it and flashing completed but I cannot get the wifi of sonoff!!!

Hi @Steveuk23
I mean, I cannot detact sonof wifi

Did you follow that guide ?
Did the flash go ok?
If so power on the Sonoff and then hold the button for 20 seconds then the LEDs should flash.
Turn the power off then back on again and the WiFi should show up then.

Yeah
I follow that guide and that flashing is complete success as shown.
Also I power on the sonoff and then I hold the button, but the LED not flashing. :sob:

Do you have the wires going in the right way?
One side is input one side is output.
Also when looking for Wi-Fi search for only 2.4ghz not 5

@Steveuk23 The wires going right in input side
There is no any new wifi is shown

Thank you for your help @Steveuk23

Not sure what else you can try if you say it flashed correctly and it’s wired correctly and you’ve tried resetting it.

@Steveuk23 thank you for tring :slight_smile:

As That flasher said the flashing is finish success…

Can I restore it to the original firmware?? If yes, How?

I don’t think you can unless you can find the original firmware online somewhere but I don’t think they release it .
After you’ve flashed it and turned the power on do the LEDs light up ? And when you press the button on the top does that turn it on and off.
What GHz is your WiFi is not set to 5ghz is it as I think the Sonoffs only work on 2.4mhz so you wouldn’t see it.

YAAH :pensive:

After you’ve flashed it and turned the power on do the LEDs light up ?
No
The light is turn on with original firmware only after flashing it is not work

And when you press the button on the top does that turn it on and off.:::: Nothing happen

I have 2.4ghz wifi …

Sounds like it’s not flashed right.
Tell me the name of the file you are flashing onto it.
Try flashing it again maybe you’re not getting it into flash mode are you soldering the pins in our holding them in place

The file name is “Sonoff.ino.generic.bin”.

I flashing it by getting it into flash mode by hold that button with blugin USB cable.

Yeah that’s the right file.
Have you checked your connections to the switch are they soldered ok maybe you have the TX and RX connectors the wrong way.
And have you got it set to 3.3v not 5v?
Maybe you’ve fried the board with too much power.
