I'm trying to pair two Sonoff B1, but once the lamps are in pairing mode the SSID for the WiFi doesn't even show up or disappears very fast. I tried it with 3 different devices (Android Smartphone, Raspberry Pi and a laptop). I checked the FAQ at http://support.iteadstudio.com/support/discussions/topics/11000001799 but it wasn't helpful. My lamps are breathing after toggle them 3x. For the AP pairing mode it says "then turn on and off for another 3 times". Should I see any difference? Should the breathing be faster/slower? Do I have to turn it on and off 6 times or 3 times and wait for a number of seconds? Also the breathing stops after a while and stays blue. Both lamps have the same behavior. Can someone tell me if I'm doing something wrong or did I get two broken lamps?
