I am sure I saw this as a thing, but either forgot to take a note of the name, or had a dream about self hosting this (because I'm just that sort of exciting guy ;-) )
Is there a “messaging/notifications gateway” service, which I can run as a docker container, open a web page to configure different destinations (eg slack, discord, signal, whatsapp, mqtt, etc), then post messages to that and some logic (tags, client key)sends the message to my endpoint(s)?
@shollyethan That's not the UI I have in my head*, but the fact that it supports APRS and DAPNET amongst all the things, means I don't need to look any further, thank you.
*I suspect I probably saw Apprise at the same time I was looking at something else, and merged the two in my memory.
