Cannot pair wifi smart switch

I just bought six Sonoff wifi switches but I can't get them to work. When I try and pair with the Sonoff I get the "incorrect password" message. I am using 12345678. Or it accepts the password and connects to the Sonoff itead wifi for a few seconds and then disconnects.

I have tried with two of the switches and get the same problem. I have looked at the itead guide and FAQs. I have raised a help ticket but am not getting a response. Can anyone help or give me advice?

Sandro, come hai risolto? io ho un sonoff basic che era stato abbinato su altra rete, ora ho provato in tutti i modi ma non c'è verso che arrivi infondo alla procedura. In pratica se premo per 5 sec invece che fare 3 lampi e stop, fa un lampeggio continuo, ho provato la procedura Compatible Pairing Model (AP) ma arriva al 50% poi si blocca e non da segno di vita... 

Gal Boaz, Thanks - changing to flight mode solved the problem. After I did that, I could add the device. But there were other problems like sonoff going offline after a single operation (switch on). But upgrading the firmware solved that as well. Now my sonoff works like breeze! Thanks a lot!!
Solved! 1. Disabled your mobile data first! 2. Hold button until light are blinking fast. 3. Then search the switch. 4. Your phone wil connect with the switch by wifi do nothing and wait until he throws you back to your own wifi. 5. He wil say at last: registering....

I had trouble pairing & finally  put the phone & TH16 within a few feet of the router & it finally paired.

Hi all,

I have a similar problem. Eventually I managed to get "found second generation device", found "Itedad00007xxxx", "registering device" and than  "device not exist". I have tried hotspot network from different phone, airplane mode solution, nothing helps. Always ends with "device not exist". Any advice would be helpful

Check this out, it worked for me

Just had a new model and i guess this is running new firmware so i think this is the reason why this was difficult to pair.  

Bold pair button for 7 secs and then take finger off 

Button hold for a further 7 seconds.

Then set Iphone to airplane mode. then turn off airplane mode

then connect to itead hotspot using password 12345678

can pair using ewelink apmode right at the bottom of the screen next

add your wifi password

then this will take about 2mins to pair.  older firmware seems to pair much quicker!

took me about 10 attempts before this worked and i have about 10 of these connected to my wifi already so no the process off by heart.

good luck
