I think your 100% right. I think my meal time spikes are higher because Control IQ is withholding basal.
Use it at night for some protection, but go old school during the day.
To be honest I don’t think it all that great at preventing lows. If I’m going down fast, CIQ isn’t going to help much.
I do like CIQ, but there are limitations to what it can do.
My feelings and suspicions as well. I also think it is slow to cut the basal when the cgm is going down fast but still in the 120s/ 130s. It’s going to keep sending insulin.
My endo wants me to put the exercise mode on when I’m bike riding. Often I find it’s just safer to stop all insulin when I’m working out.
Hi @RachelMaraii,
I just thought of something you can do for this. I apologize for not thinking of this sooner.
Here is a possible workaround for you. I know it is not perfect, and requires you to interact and be aware of what is happening. But at least it fixes the pump’s IOB issue.
When you see the need for your pump to add some IOB for any increases to your basal, simply unplug your infusion, do a little bolus of whatever number of units make sense, and then reconnect your infusion site.
Don’t add carbs, just do a bolus of X units. And then the IOB will be increased without any other changes to the calculations of the pump.
Does that seem like a useful workaround? I have never used that pump, but is seems like it would work, right? 
That’s an interesting idea! I’ll have to think that through.
One of the other potential difficulties is that it doesn’t notify me when the basal is increased, except by happening to notice the “B” in the upper right corner is darker blue and clicking through to see what the current rate is. Downloading my pump data gives me a graph of how much it’s been changed and for how long… But that’s not super convenient on the fly.
I haven’t had any luck getting the Tandem app to work. Besides the phone bolus feature that would be nice, I haven’t missed it enough to really give it another go. Does anyone know if the app shows you the graph of adjusted basal rates?
One possible downside is that your total daily dose recorded by the pump would be inaccurate.
But maybe that does not matter too much to you. It does not matter to me. I don’t really pay attention to mine too much. I take what I need! I don’t care what the pump says it is.
It doesn’t really matter much to me either. On the rare occasions I do go through it, it can really vary day to day. I agree – take what you need!
It does. The marks above or below 1unit shows when it has increased or decreased basil.
The mobile app and mobile bolus is a great tandem feature. I was on the fence prior to getting it, but I really like it. Not perfect, but is nice not needing to dig my pump out of my pocket all the time.
Thank you! I’ll have to give it another shot after all!
I was using the app for a while and it was draining my pump battery. This was a known problem - has it been fixed?
I haven’t had that issue. I use the android app.
I use the iphone. They might have fixed it; I should try the app again. I thought it was pretty good except for that.
Fixed but you need to delete the app and download the new one. The glitch that got it to the app would drain my pump battery uber fast. That’s what I remember worked best. I updated to vers 2.8.2 and still had the issue. I deleted the app and reloaded from the Apple App Store and the battery charge life returned to normal.
