So... ODroid N2+ is hosting a Home Assistant. Nothing to add.
I have an old Intel Nuc nuc5cpyh that is currently hosting my WordPress blog at https://some-techy-tinkering.com/. Made it self-hosted a month ago and can't be happier.
The last machine is Intel Nuc nuc7i7bnh with 2 TBs of internal and 4.5 TBs of external drives. This is my main server with:
- Nginx Proxy Manager
- Nextcloud
- Various *arr services
- qBittorrent
- Plex
Umami analytics looks exactly like what I was looking for. Thanks! ntfy looks very useful as well.
