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
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
!
