saving data readings to send later

Hi,
I want to put a AirGradient in a associative childcare facility. There, the rule for wifi is to have as little wifi devices as possible.
I was wondering if it was possible to save data readings in the memory of the AirGradient and to send it by night ? Or at least once an hour ? I don’t know what kind of memory there is in it.

It does not do this today, but the network activity it does have is very minimal
