Possibility to sync blood sugar data as well?

[JasonJShuler]

Hello! Thanks for this tool, its pretty awesome!

I was just wondering - Is it possible to also sync the blood sugar data, and calibrations?

I enter my calibrations on the pump, and they don't seem to show up in the Dexcom data - only t:connect.

If the data is available, could you point me in the right direction and I could try to do it myself?

Thanks!

Adding this functionality to be synchronized would definitely be possible, as BG data (CGM and manually-entered) is exposed via the API!

The tconnectws2 therapytimeline2csv endpoint returns blood sugar reading data from t:connect. The existing WS2Api#therapy_timeline_csv() method returns a readingData key which should contain a list of Python dicts containing the available BG data: https://github.com/jwoglom/tconnectsync/blob/master/tconnectsync/api/ws2.py#L63

IIRC, there is a field inside there that denotes whether the reading is from a manually entered BG (from the bolus screen) or CGM. If you're referring to G5/G6 calibrations I'm unsure where those go exactly, I suspect they'd be included here however (I have a G6 and don't need to calibrate).

We should add whether to upload BG data to Nightscout behind a flag, since many folks (myself included) already use xDrip to sync CGM data into Nightscout and/or already input manual BG/calibration data in xDrip or nightscout directly.

Thanks for following up!

I also have G6, but I got a box of bad sensors - two in a row from the same box (in very different sites) have been providing dangerously terrible data to the pump, and the pump has been trying to kill me as a result LOL. Since I just got a replacement two days ago, I suspect they will want more proof this time... so removed xDrip, installed the Dexcom app thinking they could look in clarity, but as I mentioned, Dexcom only sees calibrations entered in their app.

So yes my use case is very atypical ATM 😝 I agree about the flag - most people already have the sugar from other sources. Whenever Tandem fixes the constant t:connect logout issue on android... if this ran every minute (or 30 seconds if you wanted to go all Nyquist on it LOL) theoretically it could be a single source for all the data... sure seems cleaner in my mind!

That is, t:Connect -> Nightscout -> xDrip et al... I know Nightscout is designed to aggregate sources and everything, but something about a single stream is very appealing to me 😁

Thanks again, hopefully I can find some time to have a look

This is so irritating. And you can't even downgrade to an older version of the app to try and resolve it since login is broken on version < 1.5 🙃

Not sure how much hope I should put into their upcoming phone bolus implementation being good if they can't even get login sessions right...

@JasonJShuler Please take a look at in-progress: support BOLUS_BG and CGM features which provides an initial implementation for this feature, specifically via two "synchronization features" (BOLUS_BG and CGM). More details are in the commit description.

You can try this out by setting ENABLE_TESTING_MODES=true and running tconnectsync with e.g. --features BASAL BOLUS IOB BOLUS_BG CGM. Just be warned, there are likely bugs.
