Working out Sleep Phaser and Xiaomi Mi Band data together


I understand the problems of being connected to two different BLE devices at the same time, not really sure about Android or hardware limitations though, Anyway, using the Notify & Fitness Tool integration intents you could receive events for starting to sleep and waking-up and gather the data later, not in real time, so that we could integrate and have complimentary data on heartbeats. It seems that the Sleep Phaser ends up with a similar but slightly different detected deep sleep intervals and wonder if none of them (Xiaomi Mi and Sleep Phaser) are really accurate but if mixing and processing both data together we could have a really precise interval and better data overall.
