I have a Turing pi V2, currently with only one CM4 module in it, running some *arrs, paperless, smb and some monitoring.

I used to use them for all my setups. Then the shortages stopped that. Nowadays I just use one big server.

One Pi Zero 2W runs NodeRed to control a few lights in the house. Another used to run Octoprint until it recently stopped responding. I haven't gotten around to troubleshooting it yet.

I have a Raspberry pi 1b that runs adguard home and a VPN server

The only one I have running atm is for Klipper/Moonraker/Mainsail for my 3D printers.

Otherwise I find them so slow to work with that I don't really like using them, just something like an apt upgrade can take several minutes or more.

I'm using a pi4 8gb as my server, with a pi4 2gb as backup in case the first one dies. It's a very classic server, running postfix/courier-imap for mails, lighttpd for web, bind9 for dns, ergo for irc, sqlite3 for databases. I also use fail2ban for IDS and cron to run tons of various task. All of that is hosted on a Gentoo linux OS.

The one thing I don't want to use is docker. I love docker for development or for deploying the main app at work, but it makes managing updates a nightmare for handling multiple services on my server (most your containers probably contain vulnerable software due to lack of system updates), and it eats resources needlessly. Then again, it's made possible because I avoid the big webapps that usually need it.

A Raspberry Pi 3 Model B

It's connected to my 3d printer and runs octoprint allowing me to upload print jobs. and control the printer from my home network.
It serves up the Pi camera video stream.
It can also switch the printers light on and off.

No cluster setup.

I run a Pi Zero W over wifi as my backup pi-hole so that clients can still connect if my main system is updating or down. Planning to get a more powerful one for OctoPrint.

I use a RPi3 for pihole and a RPi4 with debian + docker to host a bunch of stuff (in no spécific order): goaccess-for-nginxproxymanager

I run OpenSprinkler Pi on my raspberry Pi 3 and HomeAssistant on my Pi 4. Works incredibly well for both.

Got a bunch of RPIs, some of them retired.

One of the active ones runs a MediaWiki engine (if it detects my home wifi on startup, it acts as a mirror slave to the master installation on the server, if not, it opens a wifi with my home wifi's credentials and offers the wiki as read-only).

Another one runs a DB that controls a number of ESP8266 clients controlling lights, motors, and sensors.

The first one is a Kodi player.

The second one was originally intended for RetroPi, but now it's a mp3 player running MPD, and connected to my sleep headphones.

I use RPI4 with the YunoHost platform and I think it's positive. However YunoHost does not install Lemmy on the Raspberry.

I run a Pi4B 8GB as a home server for Plex, Nextcloud, and Torrenting. Works fine for up to 1080p x264 stuff but I might grab a Pi5 or alternative when it launches because I'd like to start storing x265 stuff too. I even opened it up to a few family members outside the household too and we barely notice the extra load

I have 3.

1. Dakboard above the fridge shows calendar and shared photo album. It also runs bluetooth and serves as a relay for Homeassitant and a few kitchen devices (ie: igrill mini probe for meat).

2. pikvm for a desktop

3. pikvm+ kvm for lab rack esxi servers.

the latter two also run tailscale and allow me to SSH proxy if needed as a back VPN/remote access utility.

There is also a 4th. It runs NUT/UPS tools for their network gear and a mail relay for alerting and also tailscale so I can proxy if necessary.

Since its tailscale etc. Only key based auth is allowed on these boxes.

Raspberry Pi 3 B+ with Pihole. Its hard to look at websites without Pihole. Oh! I have another running Octopi for my 3D printer.

pi3 once died on me so i tried pine64 sbc and they never die...so no, i wont buy pis anymore.

Ones dedicated to being an openvpn host for my phone to be permanently connected to (pi4), and a second runs pihole + nginx as a reverse proxy into the rest of my http(s) services (pi3b+). The vpn keeps my phone behind pihole when mobile + gives access to lan only services.

The proxy being separate lets me take any of the other machines offline and the proxy will serve a 'service unavailable'/'maintenance' page instead of just timing out the connection. It serves 2-3 8mbps video streams regularly without issue.

I've got an original Pi running PiHole, I've got a Pi4 running my Plex + Servarr Suite, and a Pi2 B running a LAMPP stack and dev environment.

I bought a pi0 when I first started hosting things. It ran a pihole and piVPN instance for about 3-4 years before it died.

I would love to have another one, they are great pieces of hardware.. but are just scalped to hell. I'll keep buying old desktops and laptops with higher specs for cheaper until the costs go down.

I have one 3B running adguard and a wireguard vpn server. Another 4B doing the same, plus kitchenowl and home assistant.

Only use it as a backup pihole now. Used to have an *arr stack on it, but needed a beefier pc
