What should I use my RPi4 for? (biglemmowski.win)

I have a unused RPi4 (the 8Gig one) running DietPi. I did use it as a playground but ever since I am renting a Hetzner machine for (playground) stuff that I want web accessible, I don't have particular use for the Pi.

I am currently running (outdated) Home Assistant on it but there isn't much I can connect it with (yet, getting the flashable/compatible ikea smart lightning zigbee? bridge thingy is on my bucket list). Obviously I do have a pihole there.

Shoot me any other ideas I could run there. Some kind of monitoring of my rented infra would be cool (I already have uptime kuma on the dedi hetzner box). One idea I had was if there are some OSS security scanning "daemons" I could use on to monitor my other infra.

Thanks a lot!

RPi4 + USB Storage works as a network connected backup space for home PCs. With dyndns and a split vpn tunnel I imagine you could have your Hetzner machine place backups there too.
Seems both nagios and zabbix work on RPi:

Already got ssd as a nfs share in my openwrt-based router before that I did have it set up on the rpi. I did want to do offsite backup into that disk originally but I've got "only" ~100Mb/s up/down speed here so I didn't want to risk slow-downs etc (but now that you remind me, borgbackup should be rather light on traffic!).

NEMS being a whole OS is a pitty, I like the possibility to have multiple different services there.But you are absolutely right I could have a offsite resource monitoring for my Hetzner setup with these, thanks!

You can also install Nagios the traditional way with apache instead https://www.howtoraspberry.com/2021/05/how-to-install-nagios-on-a-raspberry-pi/

The port 9090 nems UI is based on Cockpit and just an apt install away https://cockpit-project.org
