Temp-Targets
What are Temp-Targets and where can I set and configure them?
A Temp-Target (or short TT) is an AAPS feature that allows the user to alter their BG target range for planned activities. This is achieved by AAPS manipulating the user’s insulin usage.
A glucose target, particularly if it is only short-term (less than 4 hours in duration), does not need to be the actual value you expect or want your glucose level to get to, rather, it is a good way to tell AAPS to be more or less aggressive, while still keeping your glucose levels in range.
Temporary targets can be defined within those boundaries :

AAPS provides for three Temp-Target options suitable for exercise (Temp-Target- Activity), meals (Temp-Target- Eating soon) and predicted hypoglycemia (Temp-Target-Hypo). Temp-Targets are located under the Actions tab.
Users should have realistic expectations on the results that can be achieved when selecting a Temp-Target in AAPS. The success of attaining a desired BG target will vary depending on a multiple factors ranging from: the reliability of the user’s AAPS settings, overall BG control, IOB, insulin sensitivity, insulin resistance, level of exertion undertaken during the exercise and so forth.
A Temp-Target can take approximately 30 minutes or longer in order to attain a desired BG target. It is impossible for AAPS to achieve a BG target with immediate effect and users should be mindful of this when selecting a Temp-Target.
The table below summarizes the features of Temp-Target- Activity, Temp-Target- Eating soon, and Temp-Target-Hypo.
TT - Activity
BG Target (depending on users« settings)
AAPS will aim to reach 8mmol/l or 144mg/dl for 40 minutes
Other considerations users may wish to factor in when selecting:
Depending on BG level, AAPS will ”decrease“ insulin usage in order to reach BG target. If BG target is not within range (i.e. above the users Profile’s selected BG target), then AAPS may keep the basal on.
In closed loop mode, SMB:
may be deactivated (discussed further below); and/or
basal may be activated if AAPS is in negative IOB or <0.
Users may also wish to consider:
selecting this TT 1-2 hours before the planned exercise to ensure reduced IOB (the correct timing for this TT will vary peerson to person); and
selecting a temporary Profile (decrease) for the duration of the planned activity to ensure reduced IOB;
ensuring TT is timed to be deactivated shortly before the exercise as reduced IOB as some users experience a rapid rise in **BG **post exercise.
TT - Eating soon
BG Target (depending on users« settings)
AAPS will aim to reach 5mmol/l or 90mg/dl for 30 minutes
Other considerations users may wish to factor in when selecting:
In closed loop mode, SMB:
will remain activated; and/or
basal may be also activated depending on the user’s Profile’s settings.
Depending on BG level, AAPS will ”increase“ insulin usage within the user’s AAPS setting parameters in order to achieve the desired BG target.
TT - Hypo
BG Target (depending on users« settings)
AAPS will aim to reach 7mmol/l or 126mg/dl for 30 minutes
Other considerations users may wish to factor in when selecting:
In closed loop mode, SMB:
may be deactivated (discussed further below); and/or
basal may be activated if AAPS is in negative IOB or <0.
Where can I select a Temp-Target?
In the Actions tab in AAPS.
select Temporary Target button; and then
select desired Temp-Target
Or clicking on the ”BG Target“ located in the top right corner of AAPS.
Press long on your target in the top right corner on the home screen or use the shortcuts in the orange “Carbs” button at the bottom.
Where can I change the default Temp-Target and override with my own preferences?
To reconfigure the ‘BG target range’ and ‘duration’ allocated to the user’s default Temp-Target settings, go to the menu in AAPS on the top right hand corner and
select Preferences
scroll down to »Overview’
select ‘Default Temp-Targets’
step 4 indicates (below) where to change TT- Eating soon time period
step 5 indicates (below) where to change TT - Eating soon BG target range (and the same steps can be repeated for TT -Activity and TT - Hypo.
How do I cancel a Temp-Target?
To cancel a Temp-Target running:
Select the “Cancel” button in Temporary Target under the Actions tab as shown below.
Or short-click on the ‘BG Target’ in the yellow/green box located in the top right corner of AAPS, and select ‘cancel’ as shown below:
How do I select a “Default-Temp-Targets”
In the Actions tab in AAPS.
select Temporary Target button; and then
select desired Temp-Target
Or clicking on the ”BG Target“ located in the top right corner of AAPS.
Or in the Carbs button
selecting the desired Temp-Target in the shortcuts
Hypo Temp-Target
Temp-Target Hypo enables AAPS to prevent the user from experiencing low blood sugar by reducing insulin intake. If the user predicts their BG will go low: usually, AAPS should handle it, but much will depend on the stability of the user’s AAPS« settings. A Temp-Target Hypo enables the user to get ahead of the predicted low and update AAPS to reduce insulin.
Sometimes when hypo-treated carbs are eaten, the user’s BG can rapidly rise, and AAPS will correct against the fast rising BG by enabling SMBs.
Some users wish to avoid SMBs being given during Temp-Target Hypo. This is achieved by deactivating »Enable SMB with high Temp-Target« in Preferences (see further below):
In (Advanced, objective 9): the user can enable “High Temp-Targets raises sensitivity” for Temp-Targets of 100mg/dl or 5.5mmol/l or higher in OpenAPS SMB, AAPS will be more sensitive.
In (Advanced, objective 9): the user can deactivate “SMB with high temp target”, so that even if AAPS has COB > 0, “SMB with Temp-Target” or “SMB always” enabled and OpenAPS SMB active, AAPS will not give SMBs while high temp targets are active.
Note: if the user enters carbs with the carb button and your blood glucose is less than 72mg/dl or 4mmol/l, Temp-Target Hypo is automatically enabled by AAPS.
Activity Temp-Target
Before and during exercise, the user may require a higher target to prevent hypoglycemia during the activity.
To simplify Temp-Target Activity, the user can configure a default Temp-Target - Activity to raise BG levels by reducing insulin usage in order to slow down BG fall and avoid hypoglycemia.
New users to AAPS may need to experiment and personalise their Temp-Target Activity default settings in order to optimise this feature to work best for them. Everyone is different when it comes to attaining stable BG control during exercise. See also the sports section in FAQ. in FAQ.
Some users also prefer to activate a Profile switch (being a Profile decrease < 100% to reduced insulin delivery by AAPS) before and while Temp-Target Activity is on.
Advanced, objective 9: users can enable »High Temp-Targets raises sensitivity« for Temp-Targets higher or equal 100mg/dl or 5.5mmol/L in OpenAPS SMB. Then AAPS is more sensitive.
Additionally, if »SMB with high Temp-Target« is deactivated, AAPS will not deliver SMBs, even with COB > 0, »SMB with Temp-Target- or »SMB always« enabled and OpenAPS SMB active.
Eating soon Temp-Target
Temp-Target -Eating soon can help accomplish a gentle drive down of BG and ensure there is ample IOB before eating.
This can be an important tool for those users who do not pre bolus, however the efficacy of Temp-Target -Eating soon will depend on a number of factors including: the user’s settings, if they eat a low carb diet and whether they are using a fast acting insulin (like Fiasp or Lyjumjev) in order to eliminate the need to pre bolus. Ordinarily, until users are experienced in AAPS they should expect to pre bolus when using Temp-Target -Eating soon and this is particularly so, if eating a high carb diet.
You can read more about the “Eating soon mode” in the article »How to do “eating soon” mode« or here.
Advanced, objective 9: If you use OpenAPS SMB and have »Low temp target lowers sensitivity«, AAPS works a little bit more aggressively. For this option there is a requirement for Temp-Target to be less than 100mg/dl or 5.5mmol/l.
How do I turn off SMB during Temp-Targets?
To action this select in Preferences > and deactivate »Enable SMB with high Temp-Target«.
This will ensure AAPS will not give SMBs, even with COB > 0, »SMB with Temp-Target« or »SMB always« enabled and OpenAPS SMB active.
