How to factory reset Sonoff touch?

I changed my router and kept my SSID and password same but Sonoff touch (3 gang ) is not connecting to the new WiFi . I am not able to enter quick pairing mode no matter how many times I try to press and hold the left most button. How can I factory reset this device, so that I can start a fresh.

Did you make sure you're only using 2.4Ghz and not using 5Ghz?
I've not seen a 'factory reset' for Sonoff devices, as I didn't think they needed one.
Does it fall back to AP mode on the second try in ewelink and find the Touch's access point?
Same here. SSID name is the same with a new wifi router. Some devices work, some others not. It would be nice to be able to perform a factory reset so there is really no problem...

Ok, problem solved. Here is how: 1. change the password of your wifi. You might have to change it to your cellphone too 2. pair again the devices not working to the same SSID but with the different new password (likely you will have to use the AP method, not the quick one). 3. Make sure they work and then delete the devices from ewe app 4. Change back the password to the original in your router 5. Pair again the devices with the old password Silly, but it worked for me.
Yes, very Silly. I've also changed the router and start the issues, finally I've tried something similar, I only put a wrong password when add the device in AP compatible method, after I delete from eWlink app and add the device again but with right wifi password and now it's working again.

Same Question ?

Is there a factory reset?

My switch blinks 4 times , than a short break and than again 4 times.

Factory reset is it a secret???!!!!

Hello, To date, I have not discovered any reset buttons in the Sonoffs, in my case what I usually do is erase the scenes, and the time settings related to the device, and delete it from the application. And I start a new connection to the Wifi. With this I have not had any problem in reusing the devices in other houses and different networks. I think that it does not do a deep reset, I have noticed that in the logs, records appear before the process described. I hope it helps you.

I have had similar problems moving a Sonoff double gang touch switch over to a new router and found how to put the device into compatible pairing mode... It was a bit odd but touching both touch zones continuously and wait past the single beep 'till the two beeps. Then release and repeat this time on second set of two beeps the wifi connection LED should then start to flash rapidly and continuously, at which point the built in AP should have  become active and one should be able to talk the ewelink app into pairing with the new wifi (assuming you are connected to the new wifi and have entered and saved the new wifi passphrase within the ewelink app). Hope it helps.

The latest firmware, v3.3.0 enables LAN mode but for me it was unreliable and frequently seemed to lockup. Only 433MHz or WAN mode seems reliable.

Guys, it's easy. Hold it for 5 secs and wait for the short-short-long blinking then again 5 secs and you get the constant blinking. Now you add the device via quick pairing mode. I guess this is it. 

Kamil While that method does permit connection to a different wifi access point, It is not a factory reset option though as the RF codes it's learned are not erased. This appears to be the closest we have to a factory reset function.

The SonOff devices do not just link via the SSID and the Passphrase but also the MAC address of the access point too which will be different if you change to a different piece of hardware to take on the role of the access point.

The most annoying user interface ever !

Still not getting my eWeLink to pair with my TX 2-gang switch. It was paired, then the network SSID changed (same router) and now I cannot for the life of me get it paired again.

My Phone (Apple) is connected to 2.4G WiFi, the switch WiFi LED is blinking 2-slow + 1-long flash.

I start the quick pairing mode on app, wait for about 2.5 minutes and get pairing failed.

If I connect using the ITEAD... SSID I get 'no internet connection' error.

The TX has a reset button on the side (using a pin to press the button) and that also does nothing, it basically just reboots the switch.

 I have done a 'factory reset' but nobody knows if it actually reset or not. 

At my wits end, do not know what to do to get this darn thing connected. 

Any Ideas ? Suggestions ?
