@pganssle For very details statistics, you would have to find a device that all the sleep processing on itself. For example the Miband/Amazfit watches report total sleep time, but the other sleep types (light/deep sleep) data are not provided by the watch but somehow (we do not have the knowledge how) calculated in their app. For many, the current implementation in Gb is sufficient but you must judge for yourself...

@cnx @PINE64 Every time I saw one of those they seemed a bit janky, but it looks like they are only like $30? If it’s that cheap I might as well get one just to have it.

TBH @pganssle I’ve never got one (not a fan of wearing watches myself), but I’ve seen people claiming that it has decent build quality. Maybe @lupyuen can give you a better overview, he has worked on it quite extensively.

@cnx @lupyuen It was only $40 shipped so I just bought it. It doesn’t have everything on my wish list but worst case scenario I gave some money to a company that’s at least trying to do what I want 😛

AFAICT the big thing it doesn’t have that my Pebble has is sleep tracking, but the Pebble is just using the accelerometer (not even HR monitoring), so I suspect higher-quality sleep tracking is possible with just software upgrades. Though I don’t know that I’ll have time to actually implement that…

@cnx At the end of the day I might end up buying a FitBit or some other “high end” fitness tracker with way more sensors and just deal with the privacy / control issues.

I’m starting to re-consider whether my privacy and control focus is really worth it since opsec is really hard and I’m protecting against a long tail risk and mostly not a concrete harm anyway. 🤷
