Each house has an single always-on VPN client (RPi) to the central server so I ssh in case something is up. Pretty much never happens, but it's good to know the option is there. Most issues are with a specific software and not the OS, so I need to have a visual to help resolve, e.g. "Where is my contact list in Viber?" or "Why do I see this page?".

Plus, I'm running Pi-Hole in docker and I ssh to upgrade it from time to time, (docker pull, docker-compose down/up, etc.). I haven't bothered automating this because some things change between releases and I still end up doing manual configuration changes.
