The genius Zdenek Horak (Tools & Mi Band) did it again. After introducing the Mi Band 2 earlier Zdenek used his BT hacking superpowers again to make even Mi Band 1.0 (Color) and Mi Band 1A (White) talk with Sleep as Android. Any firmware should be supported on those devices.
So now the only stubborn Mi Band which refuses to work is Mi Band 1S. Hopefully, we will see that integrated too one day. Let’s see.
