Selfhosted

I have a pi zero running as a doorbell camera, alongside a couple more CCTV cameras, and a pi4 running in kiosk mode connected to my motioneye server displaying said camera streams on a crappy old TV in my home office.

I run AdGuard Home (mostly for malware domain blocking and DNS caching) on my home server, and the Pi acts as a secondary DNS server. I use AdGuardHome-Sync to keep the config in sync across the two.

I have been for about a year with one 8gb Pi 4 with a 500gb ssd. I bought it as a way to dip my toes into self hosting. Started with Home Assistant OS, but now I have a bunch of containers set up, such as Home Assistant, Plex, Sonarr, Radarr, Prowlarr, qbittorrent, and a few others. I will eventually get something a little beefier to host my media, but will absolutely keep the Pi running.

I've got several for random little tasks that crop up, but main use is for the conbee II I have running the zigbee network for all the smart lights. I've got a UPS hat using some old 26650 cells for battery backup, mostly so that if power cuts off I don't run into any issues with the setup and the rare cases where I have to take the power off the server rack for whatever reason. RPi has actually been rock solid for couple years now so no issues with that side, wife approval factor has likewise been high

Also got a Turing Pi but haven't had a change to play with it too much yet. For most everything else I'm running a docker and VMs in TrueNAS, but would probably change that setup at some point..

I have a water container I need to take care of in my house. An ultrasonic sensor hooked to my raspberry 3b uploads the collected data to my vps that later serves an html through Flask to show the water level. It has a few alarms so that I can take action at the appropriate time. The ultrasonic sensors HC-SR04 suck and I have to replace them quite frequently. Other then that it works really well.

One for home assistant, one for very basic network services (dns, auth, dhcp) that I want up all the time even if I have to shut down the router+firewall. If I have to upgrade the firewall box I don't want to be unable to print, or use smart home stuff.

Home Assistant setup, along with media hosting for a hard drive full of all my music and movies.

One for pihole

I used one in the past for Unify Controller but it broke

Another one is a USB wifi hub to control my telescope equipment remotely.

I use a pi 3 to host backups from my main server via restic. I also have a pi 4 that I use as a VPN server

I've got one as a Pi Hole, one as a Kodi box, and a few others I keep around as basically electronic multitools.

Yes, a Pi 4 with 2GB RAM. It is running Navidrome (music server) with my music collection on a 2TB SSD connected to it. Works great.

The energy consumption at around 3-4 W, pretty neat!

use it for home assistant. I'm astonished because my test install from years ago on a pi that's around 7 years old is going with no intervention aside from updates. it's crazy robust.

for a while my laptop was slow and I needed a test local environment rebuilding with webpack so I set up a newer pi that ran the Dev servers so my laptop didn't choke. I've got a better laptop now.

A second one sitting in a box meant to be the first of a cluster, until they disapeared

I currently have Pi-hole and Unbound running on my pi4

I used a pi 3 to host a Foundry server (TTRPG software).

I use Docker to simplify things, since I run two instances of it. Simple port forwarding setup within the docker container. the main reason I used a pi instead of my computer is so my players could access their dnd stuff all the time.

I stopped because I switched ISPs and they won't let me port-forward. My vpn supports it but the latency isn't ideal. I host the same thing through a cheap server now.

I have a 2 running teamspeak for gaming with my wife (separate rooms and don't want to yell) and pihole. And a 3 hooked to a 3d printer running octoprint.

One runs Home Assistant (Pi4), and an older one runs RetroPi (Pi3) for my arcade cabinet.

I have another Pi3 that I used to use as a Steam Streaming device to put my PC games on the projector.

I use it for WOL on my PC

I have a couple of Pis, but currently only using the Pi 4 which is my Kodi box (LibreELEC). I planned to use my older Pi 3B as a web server, but I also have Proxmox on a NUC running as my main home server, so I don't know if there's any advantage to using the Pi at this point.

I have Home Assistant on one and Kodi (Libreelec) on another

I used to have a self-built, locally-hosted power strip with individual outlet control that served it's own interface. It was powered by a Model B+. I've since moved to home-assistant and zigbee plugs since my self-built solution was pretty bulky, but it was by far my longest lived Pi project.

K3's cluster, Gitlab, Ghost, Nextcloud, Elastic stack, and some other stuff.

I use my pi for 3dprinting management.

Testing ideas with kubernetes before moving to the POC stage
