Precisely the same problem. Anyone?
Any solution? Or do I have to buy a new one? 

Me too, I can't reset or connect any thing

Sane problem with 2 re5v and 1 basic

There is NO RESPONSE from "ITEAD Customer Care Center"

I got responce from support:
Support:
It's in factory mode which means data loss.
What happened before the problem occurs?
Did you flash the firmware?
Me:
I did nothing. No flashing or something like that. All my sonoff devices work with original firmware.
...
Finally I bought a new one and all works again.

 

Mine is also with original firmware. It is used as a garage opener and has been in an IP66 (dust and water protected) box all the time.

Thanks - Andreas Brandl


Any suggestion to solve it ?

No.

Evan no idea what happened.

Serious: All our devices became broken at almost the same time...




I encountered the same problem as Tom Ansbro. The battery runs out. After changing the batteries, the light flashes 4 times, but the relay and inching mode still work.

Hello,

I have a problem similar to yours. Is there any information about why the problem is caused or the solution?

I have not found a solution yet. Sorry! So annoying....
I received my first one yesterday and got it to connect with the WiFi and app, but whatever I tried I could not get it to learn any RF Codes or the new door sensor which I got with it. After many hours I deleted the bridge from my tablet and tried to install it on my phone, at that point it went into factory mode and I have been unable to do anything with it since. I do not think that I have done anything unusual or wrong, therefore assume it's a faulty unit. Do I need to flash it from here to get it working again? If so what with to make it function as it should? Or how do I get it out of factory mode?
