Mismatch of IOB after 2 boluses

[dompy]

Hi
I realised, that the IOB was mismatched after I've applied one bolus of 7.4 U at 1:05pm and 6.0 U at 1:17 pm. The IOB then first showed the insulin of the first bolus until it was down to 0 again, then suddenly the IOB of the second bolus appeared also. The pump showed the whole bolus amount on board, as usual.

Seems like it can't add them together?
I've updated to the dev branch. I don't understand much of that, could also be possible, that I've done something wrong there. Btw I also don't get any rawbg data, although activated in ENABLE variables.
Insulin duration is set to 3hrs in all devices.

My Gear

• Minimed 640G, Enlite Sensor
• Samsung Galaxy S4 Android 5.0.1, Carelink next link 2.4
• Uploader version 0.2.1

Greetings

Where we you checking the IOB? The Nightscout website? Are you uploading the pump events through the new 640G uploader or by hand?

RAW on Nightscout is currently limited to Dexcom only - we need to find a developer with Enlite / 640G willing to implement support on the site.

IOB on Nightscout website. I'm uploading by the new uploader app on my android. I was asked to put a issue here for repdroduction of this "failure".

Cool! Would you have the time to dig out the affected treatment entries from the treatments collection in mongolab? That might allow reproducing the issue.

I'll try....

This was bevore the first bolus of 7.4 U

{
"_id": {
"$oid": "57458222ab4ef69420ce27f3"
},
"uploaderBattery": 53,
"device": "medtronic-640g://6213-1015079",
"pump": {

},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T10:44:50.622Z"
}

This was after the first bolus of 7.4 U at 13:05

{
"_id": {
"$oid": "574586faab4ef69420ce27f4"
},
"uploaderBattery": 52,

},
"battery": {

}
},
"created_at": "2016-05-25T11:05:30.386Z"
}

And this

{
"_id": {
"$oid": "57458715ab4ef69420ce27f5"
},
"uploaderBattery": 52,
"device": "medtronic-640g://6213-1015079",
"pump": {

},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T11:05:57.712Z"
}

And this

{
"_id": {
"$oid": "57458843ab4ef69420ce27f6"
},
"uploaderBattery": 52,
"device": "medtronic-640g://6213-1015079",
"pump": {
"clock": "Wed May 25 13:15:24 MESZ 2016",
"reservoir": 189.375,
"iob": {

},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T11:10:59.012Z"
}

At 13:17 I deployed another bolus of 6U this is what comes next

{
"_id": {
"$oid": "5745896dab4ef69420ce27f7"
},
"uploaderBattery": 51,
"device": "medtronic-640g://6213-1015079",
"pump": {
"clock": "Wed May 25 13:20:23 MESZ 2016",
"reservoir": 183.3,
"iob": {
"timestamp": "Wed May 25 13:20:23 MESZ 2016",
"bolusiob": 0.093
},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T11:15:57.628Z"
}

{
"_id": {
"$oid": "57458a9aab4ef69420ce27f8"
},
"uploaderBattery": 51,
"device": "medtronic-640g://6213-1015079",
"pump": {
"clock": "Wed May 25 13:25:24 MESZ 2016",
"reservoir": 183.2,
"iob": {
"timestamp": "Wed May 25 13:25:24 MESZ 2016",
"bolusiob": 6.446
},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T11:20:58.126Z"
}

Then this

{
"_id": {
"$oid": "57458bc5ab4ef69420ce27f9"
},
"uploaderBattery": 50,
"device": "medtronic-640g://6213-1015079",
"pump": {
"clock": "Wed May 25 13:30:23 MESZ 2016",
"reservoir": 183.125,
"iob": {
"timestamp": "Wed May 25 13:30:23 MESZ 2016",
"bolusiob": 6.146
},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T11:25:57.261Z"
}

Then it goes on until this and the next entry where it changes again

{
"_id": {
"$oid": "57459b6fab4ef69420ce280b"
},
"uploaderBattery": 46,
"device": "medtronic-640g://6213-1015079",
"pump": {
"clock": "Wed May 25 14:32:09 MESZ 2016",
"reservoir": 182.1,
"iob": {
"timestamp": "Wed May 25 14:32:09 MESZ 2016",
"bolusiob": 0.146
},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T12:32:47.832Z"
}

an then this. no other boluses were applied until 16:14

{
"_id": {
"$oid": "57459c8cab4ef69420ce280c"
},
"uploaderBattery": 46,
"device": "medtronic-640g://6213-1015079",
"pump": {
"clock": "Wed May 25 14:41:58 MESZ 2016",
"reservoir": 181.95,
"iob": {
"timestamp": "Wed May 25 14:41:58 MESZ 2016",
"bolusiob": 5.8
},
"battery": {
"percent": 100
}
},
"created_at": "2016-05-25T12:37:32.953Z"
}

It might also relate to something in the new uploader. I've made a dupe at pazaan/600SeriesAndroidUploader#55. Feel free to close this one :)

[sulkaharo]

Right - those are devicestatus entries where the external system just tells Nightscout what the IOB is. The Nightscout IOB is based on the entries in the treatments collection - does the new uploader create entries there?
