+You can check current version in ewelink app. Sadly there's no way to overcome this, for now. We don't know if we need firmware >=3.1 AND ewelink registration OR firmware >=3.1 only. We haven't found a single sonoff mini with stock firmware >=3.1.

 ## current limitations
 As of today, this is a very basic script. It has never been tested with two sonoff-mini at the same time, for example (and I'm very confident that this condition is not working). Maybe this works with Sonoff Basic R3 or Sonoff RF R3, it has never been tested.
 This tool is designed to work without internet connection so it hasn't got access to different firmwares other than the 6.7.1 that is loaded onboard.
