Alot of us who have a Raspberry Pi 3 or 4 might upgrade to the Raspberry Pi 5.
Doing so would leave us with 2 Pi’s. What are some great use cases for the older Pi, that would no longer be the main machine?
Sell them used and reduce the cost of entry to other people
Here is a controversial thought; do you need to replace the 4?
I can’t speak for the OP, but in my case… It was very much a resounding YES!!! If your using Pis as general home servers, like I was, you can very quickly run into resource constraints. I wound up replacing 5 Pi 4’s with a pair of 4th gen Intel boxes and I’m still hit resource limitations from time to time. Though now it is more io related then ram or cpu.
You probably don’t need pis then you need a real server
- Octoprint if you have a 3D printer
- Volumio (or similar) if want a device you can cast music to
- for astronomy can install astroberry for remote control of your scope and camera
- run home assistant for home automation
- pihole for use as a DNS server that blocks ads
- plug a camera in and use it as a webcam/ security camera
Thanks man!
I will try Volumio for sure! I also want to try home automation some time, but I don’t think I have enough hardware to run with it yet.
I started my home assistant journey with 4 smart globes, a Google home speaker with a pi 4. I learned how to use it and started integrating things I don’t need hardware for, such as shopping/Todo lists, weather, Spotify, last.fm, calendars, basically anything I can learn without hardware. Right now I’m working on getting a shopping list sent to me when I enter the shops zone.
Then I bought a bunch of NFC tags (they’re cheap) for medication reminders, kitty litter reminders/tracking. I have a music poster in my house I’ve stuck an NFC tag to and it opens up the album on Spotify, turns on Bluetooth and connects to my speaker.
I’ve slowly been adding more devices as I go along due to cost constraints. Not that smart home stuff is expensive, I just can’t afford to do it all at once. Which also gives me time to consider/research smart devices before I buy.
100% recommend. It’s addicting actually.
Oh and you can put Adguard on home assistant too as an add on.
I hear rpi5 doesn’t come with hardware decoding, so that is something rpi4 is better at.
Good call if true
Actually need to know this. I haven’t heard about it myself, but maybe I missed it?
Apparently it only has 4k60 HEVC decode and no encoders
I’d add a 2nd Pi-hole (sounds like you have one already?) for redundancy.
I have 2 pi 4. One of them runs Vaultwarden as my self-hosted password manager. The other runs TPLink Omada SDN management software to manage my switch and WiFi APs.
