The datasheet for the RTC used within the Controllino states that it has support for alarms.

Datasheet here: https://www.mouser.co.uk/datasheet/2/530/RV_2123_C2-2308134.pdf

My goal is that an interrupt would be recieved, at which point I close a relay and start a 30 second timer on the RTC, and when the timer is finished I’ll open the relay.

The pinout table provides the pin number on which the interrupt would be received, but there doesn’t seem to be any library support for the alarm functions. Is this currently possible or will I need to develop this myself? If I have to develop this myself i’ll open a PR in hopes that the functions are made available to all.

Is this possible?

Thanks in advance.
