Contact the developer of Notify & Fitness for Mi Band https://play.google.com/store/apps/details?id=com.mc.miband1 to integrate SaA support. Notify & Fitness for Mi Band works as a standalone app with all firmwares of Mi Bands, it works very well, the developer is very responsive and it will be not as hard as trying to reach Xiaomi or reverse engineer the code. Please, Urbandroid, consider this opportunity for integration, users ask you for it for so long!

i talked to the developer of notify & fitness for miband. And he said he would very much like to support sleep as android and has tried to contact the devs. He said however that they did not reply. Please support this app as i feel it is better than the one currently supported and it has a free version.
