Switch between "complete closed loop" and a "closed loop with only Switch-off at low values"

[simonsis1002]

I am using the Android APS with a freestyle libre 2 sensor. Unfortunately, I've already seen the sensor deviate in both directions. If the sensor deviates to higher values compared to the real blood glucose value during night, the loop regulates to the target value and the real blood glucose is going to be lower than the target value. (Some of my friends stopped looping with freestyle libre 2, because they were afraid of hypos during night.

This is not critical during day, because I will realize the real blood glucose value. But I am not trusting the sensor during night. Hence, I want to use the loop witrh all features during day, and a loop 'with Switch off at low values' during night.

My actual solution to this problem is, to manually set the max IOB value during night to 0. This is very cumbersome and somtimes I already forgot to switch the max IOB value.

It would be nice if the max IOB value could be set within different time blocks. or if the automatization could set this value.

fyi: option to Open/Close loop via automation was requested at #2220

Hello rustymonkey,

Thx for the reply. But i am not looking for a automatiom between open and closed loop. I am looking for closed loop with variable max IOB. During night i want to use max IOB 0, like in objectives level 6 and during day i want to use closed loop with full options.
