Hypo Protect

[CSlycord1]

Is your feature request related to a problem? Please describe.

To prevent rebound lows during treatment; AAPS has this feature with a built in automation when BG is registered below a defined number and carbs are logged, a high temp-target is applied. This prevents the algorithm from seeing a BG spike and administering insulin which can result in a rebound low.

Describe the solution you'd like

AAPS excerpt: 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.

Describe alternatives you've considered

Manually creating a high temp-target; 140mg/do for 40 minutes. This is a current workaround that I, as one of the primary caregivers, am utilizing. We are trying to get our child to be more involved with diabetes management and this step is regularly missed. Would be nice to have the option to enable this feature or not.

Additional context

I have brough this up in the FB Trio group for discussion. Recent dialog with Dan H. Moody

Technical Details

Unfortunately I am not competent in pulling the code from AAPS to see how/ if it can be useful in translating into code that could be implemented in Trio

User Impact

Having this as an available feature (switch on/ off, off be default?) would help further "automate" or alleviate diabetes management- this feature will help prevent rebound lows when a fast acting carb treatment is administered and Trio recognizes a fast BG rise against the current target BG.
