I have 10 S20 switches
I first purchase 5 and able to pair them
they all pair and work like a charm
I Purchase another 5, 2 month ago
I am not able to pair the devices
I have 2.4G network which i use to pair
I try to re-pair one of the old S20, and it fail as well
The S26 Pair immediately
The S20 is fail to pair
I try the followed trick
I name my phone hotspot to the same name of the home network
Shut down the home network
Then use another phone and i been able to pair the device
Thank i shut down the phone hotspot and turn on back the home wifi, and than i been able to work with that
But it is an hustle and i do not want to work like that
I am reminding again, the S26 which i purchased work like a charm
It fail on firmware version 1.6.0
It fail on firmware version 2.6.1
I have several Sonoff divices but last week I bought a S20 and for pairing I need push the botton and the led blink 3 times and stop and repeat. But when I try to push again in order to have the led blinking fast, the divece stops and no led is blink.
I tryed several times and several way but I cant.
And of course, in I cant see the led blinking fast is impossible pair it.
Thank you for you help.
