available in data protocol/documented in spec but not yet implemented[?]
unknown whether available in data protocol/documented in spec; not yet implemented*[ ]
TODO: needs implementation![ ]
unavailable in data protocol and/or not documented in spec and not yet implemented)
Required if Present
CBG
[x]
cbg values[ ]
units of cbg values (read from device, not hard-coded)[x]
out-of-range values (LO or HI)[x]
out-of-range value thresholds (e.g., often 40 for low and 400 for high on CGMs)
Device-specific? (Add any device-specific notes/additions here.)
- internal glucose unit is always mg/dL for this device, independent of display unit
- out-of-range thresholds are 41 mg/dL and 499 mg/dL
- out-of-range measurements are reported as values 40 or 500 respectively

No Tidepool data model (yet): volume and/or vibrate mode of all alerts (can/should go in payload
).

"Bootstrapping" to UTC
[x]
index[ ]
UTC timestamp (Hey, one can dream!) OR[x]
internal timestamp or persistent log index (across device communication sessions) to order all pump events (regardless of type), independent of device display time OR[ ]
ephemeral log index (does not persist across device communication sessions) to order all pump events (regardless of type), independent of device display time
[x]
date & time settings changes[x]
usecommon.checkDeviceTime(currentDeviceTime, timezone, cb)
to check against server time
Device-specific? (Add any device-specific notes/additions here.)
No Tidepool Data Model Yet
NB: You can and should add to this section if there are other data types documented in the device's data protocol specification but not part of Tidepool's data model (yet).
