My Sonoff has the problem that it frequently looses the connection to "the server".
When I Power on the Sonoff it connect to "the server". After some seconds the green LED is constantly green, and the Sonoff can be switched on/off via the App.
Some time (sometimes a few minutes, sometime 15 minutes) later the the green starts blinking "fast", and the App reports the device disconnected. Waiting for a reconnection does not change tis, it stays unconnected.
I checked that the Wifi Router is working.
When I remove power from the Sonoff and power it up again, the Sonoff "boots" and after some seconds the led is constantly green again, and is accessible by the App.
In this way the Sonoff is not able, so what can I do? I guess the Sonoff should reconnect automatically, or this not implemented?
Many person have the same problem, i think the dns server sonoff temporary died.
Any solution for this problem dude?
We are very sorry for the problem.(Explanation On Service Disruption In EU: https://www.itead.cc/blog/explanation-on-service-disruption-on-eu-region/) We are fixing the problem, and the servers will be unstable in the next few days. We'll try our best to solve it. Thank you for your understanding.
I am having this problem also with no connection if I reboot the sonoff it will work for about 15 minutes then loses connection I have no problems with any other smart products only the sonoff I have tried 3 times deleting it and reconnecting to wifi. I only purchased it last week and its on latest firmware.
This seams to be a common issue with Sonoff. I found a solution which made this less painful. On your router please make sure that 5GHz WiFi is disabled.This will reduce issues where the device becomes off-line. It doesn't resolve the problem as I am still having this issue however it is happening not as often as it used to.
I look forward seeing new version with LAN connectivity :)
I think I've found an workaround to this problem. This might not be the same for those with sonoff switches losing contact after 15 minutes, but in my case sonoff loses contact after several days.
I have different switches:
Two weeks ago, I configured a scheduler for automatic restart once a day for the wifi router. As a result, none of the switches have lost my connection with the server.

For my Mikrotik wifi roter, the automatic restart option is configurable in the router's web interface. If your router does not have this option, you can use a timer that switches the power to the router once a day.
