Pine64 pinetime supports custom OSs but I don’t know of any with sleep tracking. It is only like 30 bucks though.

Edit: GitHub repo for a wasp-os sleep tracker for pinetime: https://github.com/thiswillbeyourgithub/sleep_tracker_pinetime_wasp-os

After going with Xiaomi devices for some years (with Gadgetbridge) I revived my trusty Pebble Time Steel only yesterday. This thing is 8 years old and doesn't do heartrate but it still tracks my sleep more precise than any of Xiaomi's devices ever did. Maybe you can find a device in good condition on eBay? Be sure to ask sellers for daylight pictures of the screen with settings menu or a bright watchface. If the battery is dying the screen looks like nacre cause it's being lifted by the battery.

The best way I know of is finding a device that's supported by gadgetbridge: https://codeberg.org/Freeyourgadget/Gadgetbridge#supported-devices (be sure to check the warnings, some devices require you to pair with the OEM app first or possibly even keep the OEM app around)

Though, I used this with an Amazfit Bip and didn't find the data particularity insightful. It often was just straight up wrong about whether I was sleeping or not. So, I too am curious to see what other answers come in.
