Could a closed-loop system deal with my use case?

Does the closed loop suspend all basal if necessary? Our problems are night time lows if we don’t suspend it altogether for 5 or 6 hours per night.

It would depend on the algorithm, but, in general, a closed loop algorithm would deliver little or no insulin when it predicts a low in the near future (or when you are low of course).
