Smart home setup

Look into Home Assistant — integrates with most devices, runs well in Docker.

Media server

Jellyfin (free/open source) or Plex. Jellyfin fits the self-hosted ethos better.

Bitcoin / crypto node

Bitcoin full node (bitcoind) or Lightning node (LND). Also look into Monero mining — CPU mineable, may be viable on home hardware.

Remote SSH access

CGNAT blocks port forwarding. Plan: Cloudflare Tunnel SSH (cloudflared ProxyCommand) for work laptop. Tailscale for phone if ever needed.

Fix email spoofing

Add SPF (v=spf1 -all) and DMARC (v=DMARC1; p=reject; sp=reject;) TXT records in Cloudflare DNS for clemates.nz.
