Node-Red GPS diff alarm

Hi folks,

Sailing in the Baltic has new challenges with GPS not always reliable.

Made a simple Node-Red flow that compares the different sources for navigation.position and creates a notification if diff is larger then X.

Seems to work but failing to create audio on the "server".

KIP picks up the alarm and sounds terrible ๐Ÿ™‚ first screenshot

Freeboard do not see the alarm, second screenshot

Trying with Notification player but same as Freeboard does not see the alarm, third screenshot.

The flow simply creates a Signalk Notification when diff between GPS sources are larger than X meters,

The notification is visible in data browser, fourth screenshot.

The best solution would be to connect the Raspberry to a speaker and have that sound the alarms.

Any guidance appreciated!!
