Re: Opencpn alert buzzer
Might be a handy feature but certainly a lot easier to just get a cheap usb powered speaker.
Does Opencpn write a log entry when an AIS alarm goes off? Shouldn't be too involved to write a little node-red flow to watch for changes in the log file then switch a gpio pin high if a change matches what an alarm entry looks like(if it does get written in the log file).

The watchdog plugin can do it for many types of alarms, but so far this does not include ais.
