Hiya!

I have a Raspberry Pi 4B set up as a print server, so it has to run 24/7. But it irks me that it’s mostly idling.

I’d move my website to it, but I don’t want to deal with it being open to the internet. The same goes for an e-mail server.

I was also thinking of running a Minecraft server on it. (Being able to play on the same world from different devices is kinda cool.) Alas, my RPi only has 4 GiBs of RAM. I worry that such a load would interfere with the print server.

Any ideas what I could run on it?

    Yeah, I’m running home assistant with 43 Zigbee devices, 20 Wifi connected devices including about 150 channels of medium-high (once a minute) data logging (temperature, humidity, signal strength, sensor positions, radar occupancy info, etc.), and a Music Assistant instance, and while it’s streaming net-radio I’ve only got 98% idle on my Pi’s CPU, feeling the squeeze already /s.

    Your Zigbee hub will run out of capacity long before the Pi. Solution: run multiple Zigbee hubs when you get to that point.

      I have around 100 ZigBee devices, roughly 40 WiFi devices, three dozen integrations, Music Assistant, etc. And yeah I was feeling the squeeze. 🤷 Let alone security cameras…

        Security cameras will do it, and the Pi5 doesn’t have hardware decode for h.264 the way the Pi4 does, so that becomes a big drain, particularly if you don’t drop the frame rates. I run a separate Pi (5, unfortunately) with a HAILO 8 hat (fortunately) for 5 video streams on Frigate - it needs some airflow to stay cool, but is only running about 30% CPU utilization for my streams.
