Greetings, I have several Sonoff devices that work fine. Today tried to add two more of Sonoff Basic, and got into the following: when I try to pair, my smartphone YES finds the unit, I can change the name of the unit, but then LED never turns permanently green, it keeps flashing, and smartphone may not communicate with the unit. I tried this several times; all with the same effect.
What can be the problem? I would suspect my network, but other units work, and the system does find new units. Looks like there is some problem with registration.
