Repurpose a Raspberry Pi4 to What?

Channels DVR Server
#1

I used a Raspberry Pi 4 (4GB) as my Channels DVR server from 2021 until last week. It worked very well for this job but as it is no longer supported I migrated to a N95 mini PC last week. The N95 is working well for channels but I now have a unused Raspberry Pi 4 in my office.

Ideas for what I should use the Pi4 for in 2025? Previously it ran the custom channels image off a USB HDD but I think I have it booting Raspbian off a micro SD. It's obviously low performance but also super low power draw.

I still use multiple RaspberryPis, and find them quite useful.

I use them for:

2x Pi-hole servers

1x PiKVM (DIY v2) with 2x PiKVM switches (console access to everything in my rack)

3x arm64 and armv7 targets for multi-arch Docker container builds (much faster than using emulation)

6x UPS controllers for my UPS orchestration system, as described here:
