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?
All my switches went offline today!
Your solution is only possible if you have acces to the router. If the installation is in an other building it is not possible.
I have carefully followed the instructions received from Studio Itead and have changed ISP, changed routers, turned off all other devices.....etc. I have the same problem with 4 devices out of the 8 I own. They all worked at one stage. Although the devices appear to pair correctly they revert to the 2s blink. Apart from sending them all back to Amazon under warranty, does anyone have a solution?
