You can already set up your photos to automatically save in Nextcloud? With Nextcloud sync client’s auto-upload feature? I have photos on phone and Nextcloud only.

I use this too. When SNMP is set up there are loads of things you can monitor with LibreNMS. Much less of a learning curve than Grafana + Prometheus, although the latter probably has some nice tweaks available that SNMP does not provide.

She uses Arch btw
