Funktionsanforderung LGS

Open andiww opened this issue 5 months ago • 13 comments

Hallo, ich wünsche mir eine wahlweise zeitliche Begrenzung für LGS denn nicht nur ich habe es mehrfach vergessen in den Closed Loop zurück zu setzen ein Anstieg nach dem Essen ist deshalb besser zu kontrollieren

Viele Grüße Andi

Happy to repeat in English. LGS stands for Low Glucose Suspend in AAPS. I would like this function to have an optional time limit so that it switches back to the closed loop after a certain time period.

Best regards, Andi

Ich brauche das eher spät Abends und vermisse da auch eine Option, dass LGS zeitlich zu begrenzen, damit der Loop nachts wieder aktiviert wird.

Can you please explain more what are the requirements, and please write in english, as most of developers are not from german-speaking countries, so we lack the knowledge of your language...

What is LGS? I could translate most of what you said, but got stuck with this? If you describe it more in detail we could offer some suggestion how to work with current system...

But it would be better if you ask your question either of Facebook (lot more people, and there is also german speaking AAPS group there) or on discord, because you can get answer much faster than writing here... You should have open ticket here only after you talked everywhere else and got more information.

Hallo ich habe meine Funktionsanforderung zusätzlich in Englisch editiert Beste Grüße Andi Hello, I've also edited my feature request in English. Best regards, Andi

What is LGS?

I don't understand German either but generally, LGS = Low Glucose Suspend

Yes, that would be a great feature. I often use the LOW GLUCOSE SUSPEND function and I miss the option, to set a time period for that during the activation process, see the added picture. Kind regards.

What do you use LGS for ? Loop does LGS automatically, no need to set it up. Choosing LGS only hinders the loop.

robertrub avatar Aug 02 '25 21:08 robertrub

Choosing LGS only hinders the loop. Yes, that‘s what we need it for. Options: 1.) Loop: Basal, SMB, LGS protection 2.) LGS: Basal, LGS protection 3.) Suspend Loop: only Basal, no LGS protection 4.) Disconnect pump: no insulin delivery

In some usecases the SMBs (Loop) are not desired. But we need the LGS protection (against low glucose). The LGS option then is a good choice for a few hours, but only for a few hours. All other options don‘t give us the needed LGS protection and deliver insulin without the aggressive SMBs.

There are easier ways to stop SMB. You set No SMB with high TT and when you don't want SMBs, you just set a high TT for x hours. High TT can be as low as 101mg/dl...

This said, if you need to stop SMBs (except when exercises), then your profile needs tweaking.

I don’t know this function and I believe it‘s not easier than my and Andi‘s way via LGS. Sometimes there are TT solutions with odd and even temp targets to stop or enable SMB. I believe the TT target way is not a save way and for me it‘s more than a workaround than a clear solution.

And yes, there are always a lot of ways to reach the same solution. But this way is my and other peoples way. I hope you are so kind, to accept this and to help us to introduce a variable time limit for this LGS feature.

Kind regards

I'm just a user and beta tester. I don't decide anything. Just saying that running LGS is not common.

robertrub avatar Aug 03 '25 18:08 robertrub

Actually, I do prefer Low Glucose Suspend on some nights while I want to maintain my target of 90mg/dl: when the sensor doesn't sit in a perfect place, and I expect compression lows when the sensor becomes jumpy, but still works perfectly during the day for a few more days And yes, I often forget to turn it off in the morning and get back to SMB.
So, I would love to have a time limit there, just as there already is in various other places. But I have no idea whether that would be easy to implement.

I very often have LGS on, especially before and during sport. I've never missed a time limit, I switch it off after sport. However, the unlimited runtime should definitely be retained, there are definitely users (childrens) who have LGS on all the time! This is different from disconnect pump or suspend loop.

In some usecases the SMBs (Loop) are not desired.

Don't understand why you'd enable LGS. Loop is able to handle this, so if manually intervention by setting LGS is required often your profile settings (IC/ISF/Basal) are wrong. Start with disabling SMB or setting SMB less aggressive (through max basal minutes).

Optionally you can disable SMB on the SMB tab. Or choose to only use SMB when with carbs only. Next release will have options in automation to enable/disable SMB.

For special cases, try setting a temp target or profile percentage?
