@olivierlambert, To start I would like to get my backup notification sent to HomeAssistant.

I recently found the notification platform apprise and I wonder if it would be a good notification system for XOA to support. The API seems very straight forward. Would this be a good use of plugins? Ultimately I am looking for a HomeAssistant or a HACS integration but notifications being routed through apprise to HASS would be a good first step and seems like a lower barrier to entry.
