Hi all, I am having the same issue. I had the switch connected to a lounge room light, connected with the online android app, all was working fine, timers on and off also worked. Then after around 1 hour the switch was suddenly reported offline and the light was off, no indicator light either. I tried the manual button, but this appears to do nothing.
Finally I removed power from the switch and when I reconnected the power and the indicator light started flashing again and went through the cycle of reconnecting, the app on the phone still said the light was on, so to turn it back on I had to turn it off on the app and then turn it on again on the app.
The model is listed on the app as sonoff pro and the firmwarer version is 1.2.0 and it has "latest" on the far right of the screen next to the firmware version.
WIFI connection lost - After one day working well the WIFI has lost. This issue is repeating daily. Can you help?
Since the initial issue, I have had one instance again, it seems to be much more stable here now, so it does appear to be an issue with the connection to the servers from what I can see from my observations.
Will need to see if I can bring it in-house or at least to my local telehoused server... but that will be a job for later.
But other than the couple of hick up, a brilliant device that appears to work flawlessly.
