Struggling to find the usecase for apprise, I think I'm missing something major :D

Can you run apprise centrally and have it receive on multiple channels (smtp, webhooks, maybe syslog etc)?

I.e. can you have it independently hosted and apps/services send messages to it which are then forwared by apprise via the preconfiged channel (email, discord, signal etc.)

My scenario is (simplified):

I have homeassistant automations running which send smtp messges to a local smtp relay which forwards the emails via gmail to me.

I now have a requirement of another server that sends notifications via a webhook (that is the only supported method).

How can I receive messages on multiple different channels (smtp, webhooks, maybe syslog etc) and send via smtp (or something else I choose in the future). Is apprise going to help here?

TIA!

Just from 2 days ago: https://www.reddit.com/r/selfhosted/comments/17ffx39/eli5_apprise/

I would use n8n for that, you can feed almost anything as input to it, and output it as almost anything. Similar tools are automatisch and activepieces.

Thanks, I did look into n8n, but I couldn't find an SMTP trigger? At least it doesn't look to ship with one built in. And I did like the fact that it has Google Tasks as a node, send like that might be the way for me

It may be me, or Reddit could be flaking out, but it appears that everyone except you and I have deleted their comments. I also cannot reply to your comment about N8N, so I am commenting again. Weird...

I recommended Pushover in my previous comment. To address your initial question, I'm running Docker containers for Mailrise, which provides an SMTP gateway that embeds Apprise code, and also Apprise standalone. I use Mailrise for services that support only SMTP notifications (e.g. Proxmox). Mailrise translates an email message and, using Apprise code, submits it to Pushover. I use Apprise standalone for receiving notifications from Healthchecks, which monitors cron jobs. Healthchecks supports a number of notification services, but standalone Apprise was the best fit for me.

As I understand, Apprise has its own light-weight HTML API for creating and configuring notification endpoints. It can create a webhook endpoint, but I don't believe it receives messages as webhooks.

Like me, you probably will need multiple services. I tossed up an N8N container out of curiosity. It can accept a webhook and then act on it. It also supports Pushover. So, it looks like a webhook to N8N can be translated to a Pushover notification. Using Mailrise (for SMTP messages) along with N8N (for webhook and other messages) should provide the extensibility you're looking for.

Again, I highly recommend Pushover. Receiving notifications from many different sources, that are organized into "applications" with their own icons, in one mobile app is a tremendous benefit... to me anyway.
