In reply to Rui Santos. I just ran tasmoto tasmotiser and it has the option to save the original binary to your pc for use later if you choose.

Has anyone used a Sonoff Touch US Power Ver 1.0?

It uses a iTead PSF-A processor which is a ESP8285 processor.

Not sure what Arduino version I might use?

Hi Keith.
Basically, after you flash the SONOFF with a custom firmware, (as described in the blog post) I don’t think you can reverse those changes.
Unfortunately, SONOFF doesn’t provide the original firmware.
If you need to change the SSID and password from one of our examples, you just need to modify the sketch and flash the SONOFF with that sketch.
Regards,
Sara

I’ve changed my router and now my sonoff switch won’t reprogram to my new router?

Is there a way to reset the switch to factory defaults ?

In reply to Leo Diaconu. Which LED blink code are you talking about? Did you select the DOUT option during the upload in your Arduino IDE?

Hi.
Yes. That FTDI module works, but you might have to install some drivers in your computer.
Note that there’s a jumper wire to set the operating voltage to 3.3V. You need to place the jumper wire in 3.3V rails, otherwise you may fry your ESP.

Hi,

Will any 3.3 V FTDI module, like the one at the next link, work?

Thanks in advance for your answer,
