In the vein of hydro homies, I have dubbed this project "Agua Amiga". I've got 6 features planned:
- Track and display water intake towards a daily goal
- Track and display streaks (so many days hit goal, maybe just drank water at all)
- Save water data to a file somewhere in an easy to analyze format
- Preferences dialog to set goal and units that should be used
- Collect sip data from Hidrate Spark 3 water bottles
- Allow adding water drank from non smart containers
Note about units: the UI will allow using either mL or oz. The program will always use mL in the data. It will convert to oz when needed to display information.
Goals: a list of daily goals. Most recent row is current goal. End time of goal is implied by start time of next goal.
- volume (always uses mL)
- time started
Drinks: a list of water intakes.
- volume (always uses mL)
- time (time of entry for manual water entry, time of drink for smart water bottles)

We talk to bluez bluetooth devices over dbus. The dbus_next library is integrated with the Glib MainLoop. The understanding so far, is that as devices are discovered, the events will be triggered inside of the MainLoop and will get processed, including reading sip data and storing it in the sips_stream deque property on the bluetooth scanner. Then there will be an idle callback that will pull all the queued sip data and update the UI and write to the database.
Documentation of the Hidrate bottle communication protocol https://github.com/choonkiatlee/wban-python/blob/master/Hidrate.py Copied the sip notifcation parsing code.
The BtleDevice class is inspired by https://github.com/ukBaz/BLE_GATT and implements a kind of asynchronous version of its API.
