I recently started using n8n in my homelab, and I'm curious how others are making use of it.

So far, the only actually useful workflow I’ve built checks my Headscale server (hosted on a VPS) and verifies whether the Tailscale clients on my TrueNAS Scale box, OPNsense firewall, Flint 2 router, and a VM inside Proxmox are connected. If any of them are offline, it sends a Telegram message to my monitoring bot.

Would love to hear what kind of automations you’ve created!

UPDATE: I just built a new n8n workflow that fetches the top posts from r/selfhosted and uses OpenAI’s GPT-4o to extract any open-source tools or projects mentioned. It summarizes each with a one-sentence description and a link, formats it all in Markdown, and sends it straight to my Telegram bot!

I’ve scheduled it to run every 24 hours — though I’m not entirely sure what timeframe Reddit’s “top” posts actually cover. Is it based on the past 24 hours, or something else?

Result from today's top posts:
