Homelab Dashboard

Quick update on my personal homelab server.

I set up a dashboard using homepage to monitor and manage all my services in one place. Though it was a bit tedious to set up, it turned out well.

I also setup a Debian VM on my proxmox to host some of the applications on docker.

The applications I am hosting through docker are:

• FreshRSS - RSS Aggregator
• Memos - Self-hosted note-taking application for capturing and organizing thoughts
• Wallos - Open Source tool for tracking and managing personal subscriptions
• Mailcow - Full-featured email server solution with SMTP capabilities

Setting up Mailcow has been rewarding. As now, I am able to deliver some of the notifications from my applications directly to email.

Example of some of the notifications are:

Torrent download complete notification through qbittorrent.
