Hey gang, recently rebuilt my home server using docker and portainer and I've been having a blast curating the different things on it. Homehub has the spouse absolutely stoked and she asked if I could get it to send notifications. I honestly have no Idea so I thought I'd ask here.

Is there a reliable way to send notifications from a home server to smart phones? I'm already set up for remote access, but I'm still new enough that I don't even know how to look for that.
