Hi,
there are projects who listen on the CAN bus / NMEA 2000 and will trigger on selected alarm messages and change the state of a pin.
Since SignalK now digest and display NMEA data I'm missing a module, plugin, application that will trigger on these alarm messages
and alter a pin on the RPi via a DC solid state relay sound a nice loud alam horn/buzzer, light etc.
I have looked for this with limited success, I might have overlooked it, but nevertheless I would like to have this functions present with the RPi.
Building yet another device to connect is possible, but far better to use the already present computer.
It should be a doable job to intercept these alarm messages and use GPIO to convey the alarm to a pin.
