Well, I have the same issue. And I think I've seen a couple of others, too... A few weeks ago, I ordered and received my first two Sonoff's... Flashing and configuring ESPEASY was a breeze, so I ordered 3 more from a different seller @ aliexpress....These 3 seem to do something whith stock firmware, but after flashing, they're all dead.
I'm beginning to suspect that I 've received a 'cheap chinese knockoff' of an already cheap chinese product:
- Housing of the first batch is matte grey-ish, and feels rough. 2nd batch is just shiny white.
- Cablecovers of the first batch fit nicely. 2nd, not so much.
- Lettering on top is just... Different. Slightly different font, slightly thicker.
- Even the WiFi symbol is a bit bigger. Strange, isn't it?
- Warranty sticker: Looks the same, but if you look closer, it's not. Working ones say 2017 5 1, and the dead ones say 2017 5 15, by the way.
- PCB, same differences, silkscreen texts rougher and bigger, Soldering (especially on the high voltage tracks) just ugly.
Still, if anyone has a real clue on why these things won't work after flashing, i'd like to know too....
