Hello, I'm having a problem with a Basic sonoff. When I try to pair in common mode the app can not find the device. When I try to pair with the second mode (AP compatible) it identifies the device, but the device appears as offline.
check if you have connected input live and neutral wires properly. then if you have the firmware to 1.6.0 then use compatible AP mode by pressing the sonoff button for 5 secs and again for 5secs until you get fast bkinking green light. then update the device then dete it and add it again in simple touch mode... that will do the job :)
