Mr. Mauro Mowszowicz, How can I send the devices ID if I can NOT add these two new Sonoff POW to the EWeLink ? I can just right down the POW number which appear short moment during pairing. Do you want this number (e.g. ITEAD .........................)?

How do I cancel notifications for this topic?

Will see. Have been back online yesterday, but today again offline from morning. Not promising for now...

I bought 5 days ago Sonoff TH16. Still continuous no connection to sever.It look like lost money .... Probably I will try solve it upgrading other soft like: SUPLA, ESP Easy, AFE . This work is extra pay about 10$ with sending cost, but it looks that is no other way if I do not want put this device to trash. I found :http://allegro.pl/zmiana-firmware-w-sonoff-supla-esp-afe-i-inne-i6860182501.html
I'm another one with this problem. Can someone recommend me alternative to their Sonoff POW coz I don't have any more patience with them and their server problems.

 

Hi,Bjarne Hørbye:

Did you have check your router account and password is right? please see attachment.

Did you have connect too much device to your router?

Please refer to link at first: http://support.iteadstudio.com/support/discussions/topics/11000001238

It's amazing that they do not solve this problem.

I have another sonoff running for months correctly, now I have bought a new one, but, in the ewelink app, it always appears as "offline", while the other sonoff works correctly.

I can ping eu-disp.coolkit.cc without problems, I can connect to the new device sonoff from my phone's wifi, everything seems to be correct, but, the new device always appears as "offline" in my ewelink app and the device it is always with the double blinking that indicates that it does not connect to the server.

I have tried all, but its only 1 i Can connect, is it possible for you to reset my account? I had 2 up and running, but 1 failed after an upgrade. The one thats work is not upgraded. The last 3 dont connect.
Today I got email ansver from ITEAD: We have do some change on our server,can the device be online? please try. ----------- Now my Sonoff TH 17 is online and working perfectly !!!!!

Good morning,

I live in Brazil, this week I bought two devices (Sonoff 4CH). One of them is not connecting to the Server.

Both devices are getting IP address and connecting to the router.


I did the following troubleshooting :  

Another device works in the same conditions

Ping Servers Ok

Restarted device

Disabled Firewall 

Changed DNS

Turned off all devices in my network, except for Cellphone and  Sonoff.


Could you please help ?

Thanks in advanced.
