Generate Notification from "True" "False"
I have bilge sensors cross my boat using sensesp. Amongst other things they return a "true" or "false" of the state of a float switch. I have these displayed on a KIP dashboard. However last weekend I had a bolt failure on my saildrive that resulted in a minor leak. I realised I would really like to know about this more quickly in future. I have played with various plugins that generate notifications such as "Zones" but these all work with numeric values and not boolean values.
Does anyone know of a plugin that can generate a notification from an existing path that is boolean please?
Thanks

Nothing I can think of will do that. You could use node-red, or send another path too that has a numeric value.
this what i do (similar setup with sensESP sensors)
NodeRED
to generate notifications in signalk use a “send notification node”
For remote alerting
ie to your phone or tablet when away from boat,
“pushover” plugin .. its very configurable allowing selected notifications or all .
hence, the nodered flow will monitor the path generated by sensESP, and react when it changes logic,
sending a notification into signalk; and the pushover plugin then does the external alerting.
if your not familiar with nodered, let me know i can paste a sample
subscribe node (to listen to the path created by sensESP)
switch node (to detect the path value .. in my case sensESP generates “0” or “1” .. where one is an alarm)
notification node (which sets the notification path into alarm or similar state)
..
then in pushover plugin … either allow it to send “all” notifications as alerts, or setup for specific notification paths
in your case, the switch node need to have true and false to trigger the respective outputs to the notifications nodes
(ie set the alarm and clear the alarm)
Thank you
