Crazy BG levels for the past 24 hours (See picture). Things have been working relatively well beforehand but appears basal and temp basal don't seem to be as effective although boluses seem to be working well. Odd, we had a pretty smooth overnight but chaos again after waking and breakfast and the rest of the day has just been chasing highs and lows. Son changed site 22 hours ago so thinking the new site may not be infusing as effectively and subsequently, the smaller basal amounts are not being absorbed as well. Whereas a higher % of the larger bolus amounts are infusing. Any thoughts on potential OpenAPS system issues before we change out sites?

I am trouble shooting bt set up: have a android oneplus 1, dexcom g5, xdrip+, OpenAPS. my rig use to be working fine with BT and BT tethering but now wont work when I leave my house (WIFI) its not commecting to BT. I cant figure out what steps I need to do to get the BT up and running again? "cant get device info: no such device" is what it says away from the house and WIFI, at home it connects fine....
when I am not at the house

right now at home it finds both my phone and the rig

@Kdisimone Thank you. Very interesting to see how you and other families manage all these variables with their teens. Luckily for us, my teenage son doesn't have the sensitivity to protein--as he is trying to put on some additional muscle for his sport teams and he is eating a lot more protein. On the other hand, he is very sensitive to fat once it goes above 40g of fat. The magic formula for us was just setting a 150% temp basal for 8 hours post meal and that kept him in range. We, thankfully, never had to deal with carb equivalencies for fat or protein (just eyeballing total fat g's) Selling my son and wife on taking on counting and calculation of entirely new group of nutrients will most definitely not go well :worried: Anyhow, I am hoping we can simply add these extra carbs for the fat at the beginning of his high fat meals and let the AMA go to work and effectively simulate our 150% manual temp basal.

bolus snooze.... I am using a DIA of 5 hours, and the divisor of 3.5, and now 2.5 but openAPS is still low temping eventhough we haven't even gotten a - value yet
I don't understand. I know it is a huge breakfast bolus...but why is it still acting when I changed the dia divisor by 2.5?
I thought it is supposed to wait in this case (2 hours) before taking action
or am i wrong?

This kind of stuff can't be solved by reasoning in generalities. We need to look at the specifics of individual decisions and see what factors are contributing.
What I can say is that a higher divisor will result in a shorter bolus snooze. You probably want to leave that at 2 and look at your ratios etc. to see why it's predicting a low.

I should leave it at 2 Scott, even if the DIA is set to 5?

@scottleibrand I'm having some issues with monitor-xdrip.sh not copying new glucose from the xdrip folder despite all the checks for newness and timeliness passing. If I remove the $directory variable from this line it seems to work. I confess I don't know what $directory does, and Google hasn't been much help. I assume it is supposed to get us back to root or something. Any ideas what could be going wrong?

In the "antenna tuning" section of our docs (https://openaps.readthedocs.io/en/latest/docs/Gear%20Up/edison.html#explorer-board-antenna-tuning-optional) there is a picture of an Explorer Board with external antenna attached. Do we know who's rig this is? Interested in their "real world" experience with range extension.

someone reported on fbk earlier this week that they were getting 20ft instead of 10ft, others have reported less range improvements w/ the antenna, others get none at all - so it's not a 100% silver bullet

Yeah, I've read on FB, too. My first rig with built in antenna gets approx 15 feet. Still building my second rig after exchanging the Explorer Board. Understood about the silver bullet.

@thebookins looks like $directory was copied from another script that actually sets it. since none of the other lines use it, a PR to remove it would probably be in order if that makes it work better.

I can't give up my home and office rigs with the TI sticks because of the range. I tried the antenna on the explorer board and I agree with the ~20ft

I've been trying to correct problems with alternating extreme highs and lows since the school year started (T1D is my 6 year old daughter). I've managed to blunt the extremes, but we're still getting a yo-yo effect. Does anyone have any ideas about the next step to try based on the data from today below? Breakfast eating soon was 45 minutes prior to meal and prebolus of about 10 minutes prior. BG rose after breakfast, peaked above range about 1.5 hours after breakfast, and then started to drop too fast. School snack is at 9:30 am. I programmed eating soon to start at 8:45 am, but had to abort because bg was dropping too fast. This snack resulted in another high, peaking about 1 hour after snack, and then a drop that started to accelerate by lunch time at 11:45 am. I did let a 45 minutes eating soon run prior to lunch and prebolus was 15 minutes prior to eating. This resulted in a fairly flat, in-range, post-lunch bg beginning 1 hour after lunch bolus and lasting for about 1 hour. This was followed by a precipitous drop in bg (starting about 2 hours post-bolus). I have a couple of theories about what's going on: (1) could be mostly a timing issue (e.g., need to do eating soon earlier to prevent high and then subsequent crash); (2) could be a combination of timing and too low CR (e.g., need to do eating soon earlier and also make CR higher); (3) could be a DIA issue (e.g., current DIA of 3 should be set to 4 or higher to account for longer insulin action). Or maybe it's something else entirely (probably this!) Any ideas?

hopefully others have some more ideas and suggestions, but sounds like you're on the right track on both timing and low CR. once we release 0.5.3 and merge 0.6.0-dev to the dev branch, there are some new exponential insulin curves you'll be able to try to help with possible DIA issues, and some updates to autotune that more directly estimate CR. the latter is not quite ready for widespread testing, but will be soonish.

Thanks @scottleibrand . I'll try to tweak time and CR to see what happens.

@bdr1177 how long are your eating soon IFTTT's set to? I know when I was first using them I set them to longer than 60 min so that they covered the post meal a bit. I realize that this may not be the exact design behind the eating soon but it did seem to help me (granted I'm an adult, larger amounts of insulin etc...) the other thing worth considering is about the actual food. I know on some foods I'm just so much better and regardless of how good the looping and settings are, I get some yoyo-ing like your daughter is finding. I can't imagine dealing with the issues of T1 that a parent must got thru (I know I'm overwhelmed personally.. ) The best thing I've found is that consistency really does help to learn what works and what doesn't. I wish you and your daughter the best...

Have there been any changes to the radio functions recently? Since a few days rigs take hours at times to start looping and return lots of different radio errors. Once they start looping, they do so with a good range and without any problems. Mmtune results are constantly great. That somehow smells like a software problem. Any ideas?

@cameronrenwick Thanks for your suggestions and kind words. I think you're definitely right that the actual food has something to do with it. My daughter is fairly picky and also has celiac disease, so her diet is difficult to manage. We should try to do better about adding protein and some fat to her meals, but its not always easy.

I've had exceptionally good results using coconut and almond flour. Don't know if either of those would fit with her needs (or school - nut rules) but they've been a huge addition to my diet. I could not live without my homemade coconut flour bagels

@cameronrenwick Do you use those as an alternative to cooking with regular flour? We don't do much baking.
cameronrenwick
@cameronrenwick
Sep 07 2017 20:19
I do. I've got 2 "go to" recipes (1 is for bagels using coconut flour, the other using the almond flour for muffins). Both are filling, tasty and I can honestly eat one of the bagels doing absolutely nothing to my pump/rig - UAM take care of it. Granted the bagel is only about 6 gm of carbs and the muffin is maybe the same when you account for a tablespoon of blueberries. If you'd like the recipe, shoot me a PM and I'll sent them off to you.

Heh: my main rig has been dying in 7-8 hours. Finally switched a different battery on to test, and I'm now still at 58% 8 hours in (about the same size battery as before). Tldr if you have a rig that starts fading in # of hours, might be worth testing some other batteries.

@bdr1177 Hey Brian, this is exactly the issue I had with my son over the past 24hours and it turned out to be a failing infusion site (which was inserted 22 hours earlier). A few hours after changing the site, viola, everything stabilized. If there is one thing i learned from working with Gary Scheiner, its that proper basal management is the foundation of good BG control. If your BGs are wildly see sawing, it can usually be attributed to either basal rates being off by x % or a failed site. The nice thing about using the OpenAPS, is that it is managing the basals so that makes the wild see sawing a bit easier to troubleshoot in this case....almost certainly a failed site, IMHO.
Brian Rabinovitz
@bdr1177
Sep 07 2017 23:49
@cbrenner Thanks for your suggestions. We had a really variable day yesterday and I do think that a bad site may have contributed to that. But I changed it last night and today was more controlled so I'm not inclined to attribute today's swings to a bad infusion site. With that said, could be the site. And that's what makes diabetes troubleshooting so ... uh ... interesting?
Craig Brenner
@cbrenner
Sep 07 2017 23:56
@bdr1177 I would have used other choice words for diabetes troubleshooting :fire: :smile: BTW, my son will vehemently protest that he "guarantees it is not the site...." I can't tell you how many times he says that to me and it ends up being a bad site. Urggh, 16 y/o boys...
