What should I use my RPi4

Submitted ⁨⁨9⁩ ⁨months⁩ ago⁩ by ⁨taaz@biglemmowski.win⁩ to ⁨selfhosted@lemmy.world⁩

I have a unused RPi4 (the 8Gig one) running DietPi. I did use as a playground but ever since I am reting a Hetzner machine for (playground) stuff 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I am currently running (outdated) Home Assistant on it but there isn’t much I can connect it with (yet, getting the flashable/compatible ikea smart lightning zigbee?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 my other infra.

Thanks a lot!

  Thanks for sharing! The only thing I’m surprised to see in your list is paperless - how long does OCR take on a pi?

    About a minute, 1:30 maybe. I use an app to upload jpegs though, I don’t have a normal scanner at the moment. The higher quality scan and smaller file size may make some steps of the process quicker (no need for alignment and color correction fox example)
    
    It doesn’t matter though. When I get home and see I got a letter I scan it and by the time I drank something, put away my clothes and stuff i had with me, the pi is done and I can edit the metadata in the web ui.

Most people seem to just want to use RPIs as a very slow Linux server for some reason…

Use it to play around with hardware integration with the GPIO pins. Get a sensor HAT and start recording temperatures, write some code that turns on/off an LED, build a robot controller, etc. There are lots of kits and documentation on the various things you can do!

  I’ve been wanting to use multiple raspberry pi zero w with sensory hats to feed data to a central home monitoring system. Would be a fun project.

  - atzanteol@sh.itjust.works ⁨9⁩ ⁨months⁩ ago
    It is! Especially if you want to write the code yourself. It’s an interesting design problem if you start to consider cases where the PI may be offline (mobile on a battery in my case). Do you lose that data? Store and forward? In memory or to a local data store? It’s a fun rainy-weekend project.
    
    Word of caution - HATs can be a rather inaccurate in their temperature monitoring. The Pi gets warm. I had done my work using a PTC thermistor that was distanced from the Pi itself. I’ve got a friend using a HAT and it’s been very off (up to 10C above ambient!). A Pi Zero may not give off as much heat as, say a Pi4 though. YMMV.

  Unluckily last time I wanted to do sensor stuff the ~20 euro air quality multi-sensor (co2, pm1-10, humidity, voc?) got lost in transit and I didn’t bother since :( The original plan was use it with my esp32 dev board (wroom32, so wifi) to have a portable sensor, this RPi was supposed to be the collection server (mqtt, influx, grafana).
  
  I should revisit this idea soon, thanks for reminding me!

  SBCs like the RPi are kind of awkwardly in-between a microcontroller like an Arduino or ESP32 that you can actually trust with handling GPIO and data logging, and a real Linux system that can actually do meaningful computational work.
  
  Pretty much the only task I’ve found them reliably appropriate for is running OctoPrint, really really light computer vision tasks for robotics, or hooking up an RTL-SDR to use as a police/HAM scanner. Outside of those, it’s so much easier to use either a cheaper and more reliable MCU or a much more powerful old laptop or desktop.

  - atzanteol@sh.itjust.works ⁨9⁩ ⁨months⁩ ago
    That’s one of the nice things about them.
    
    You can write code that has access to more resources. I had a RPI once that showed code build status on an led strip (red failed, green passed). It was a Java program that connected to AWS SQS for build event notifications. A micro controller would be much harder to do that on.

- taaz@biglemmowski.win ⁨9⁩ ⁨months⁩ ago
  I did this for a hot second (already have RTL-SDR set here) but the current location of the RPi is just bad for reception and moving it closer to some window would mean connecting through wifi (can’t lay ethernet cables, renting) and that’s bad for other services where low response times are preffered/needed (pihole) :(

    Instead of connecting it to WiFi, have a look into power line adapters. They route your internet through the copper wiring in your house.
    
    I have a router in my subterranean ground floor linked to a power line adapter, a wired router in my front room a floor up so my PC, TV, Playstation, etc are connected via LAN, and another power line 2 floors above that plugged into another WiFi router running in bridge mode, which supplies WiFi to the top two floors, and another playstation wired in to that router
    
    Basically it means that my ground floor router is hooked to the internet and everything else in the house that needs wiring in is wired in because of the power line, and the WiFi is coming from 2 routers, one on the top floor and one on the ground.
    
    My ISP thought a WiFi router on the ground floor of a 4 storey house was a great idea, but they’re stupid. WiFi should be in the highest point of your house.
    
    With a few Power line adapters you can sort your internet out for £25

  Vaultwarden is super, but I’d be hesitant to run it on a Raspberry Pi unless I had good backups in place. I’ve always run stuff off MicroSD cards with Pi’s, but I’m sure there’s a way to use real drives which would make me feel better.

    You don’t need permanent backups of it. Vaultwarden is more like a secure “syncthing”. I crashed a system with vaultwarden had to rebuild everything but after connecting it to my devices I got the passwords from them back again and nothing was lost.

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.

Immich! It’s an amazing self hosted Google Photos replacement.

Zigbee definitely fun with HomeAssistant. I have an SLZB-06M adapter which has PoE (important for me) and is a fairly “open” product (don’t need to jump through hoops to flash firmware). I read somewhere that it may offer Thread support at some point but wouldn’t count on that.

I ran HA on mine for a while before I moved it to a VM. Right now I’m using my Pi as a secondary wireguard VPN in case my primary is down for some reason.

Also, quick tip, I found that ikea zigbee bulbs work really well but have really bad coil whine when off, don’t use them for bedside lighting.

    Ah; then host the OpenVPN server from hetzner, the pi as a client, then configure the server to route traffic out through the pi client into your LAN.

First, you should something decent, not DietPi. You’ve Armbian for a ready to go experience or official Debian.

Once you get into something Debian 12, you can run LXD/LXC as a containerization / virtualization solution and use the same Pi to run the official HA VM image and whatever else you would like.

source
- taaz@biglemmowski.win ⁨9⁩ ⁨months⁩ ago
  Why is dietpi a worse choice? it’s still basically debian (11).
  I’ve chosen DietPi because of their sane defaults that I would have to setup myself like vm swappiness, fs noatime, tmp journal, and some more I am not even aware of.
  
  source
  - TCB13@lemmy.world ⁨9⁩ ⁨months⁩ ago
    Armbian has sane defaults for SBCs as well (yes log2ram so you won’t burn SD cards) and it is way more stable and polished than DietPi.
    
    About bare Debian, you’ve the images I linked to and you’ll find that they include 99% of the “sane defaults” you need to run on a SBC.

You can setup a tunnel from your Hetzner VPS to your home with say Netbird and then run stuff that would be a bit to expensive to run on rented hardware. Like say Nextcloud, Matrix or game servers, on your RPi while still having them web accessible thanks to the tunnel.

  I have a dedicated machine so the HW I have is the limit - I pay the same rate every month, no matter the usage, so with the bit outdated but still performant Ryzen 5 3600 and 64GB of RAM I was very happy to throw minecraft/zomboid/vallheim servers at it and few more services, aye aye;)

    Cool, but I’m guessing that ain’t especially cheap right? I pay $60 a year for 4 cores and 8 GB RAM (400 gb storage). Which I consider a pretty OK price. $5 a month.
