I still have a running VIA C3 (x86) server with 1G RAM, enough for low-traffic web hosting.

The only internet-connected 32-bit device I own is a PowerBook G4 running MorphOS. I have an OG raspberry pi that controls a model lighthouse that we have for decoration.
In my old house I had two pi zero W:s with IR-HATs that turned on the air conditioning when they saw my phone nearby over Bluetooth. I'd still run those if I lived there.
Which IR hat were you using? Guess I'm not aware of MorphOS.
I can't recall where I got them. Probably the cheapest stuff off of eBay or Amazon. Looks like adafruit has one, too.
The original remote for my Panasonic units sends all the settings over IrDA, so I only had to record and replay the commands to turn it on and off.
I've got a low-energy Intel Atom server. The CPU is technically 64 bit, but some of the other hardware is still 32bit, limiting you to that.
I've been running Debian on it (and several predecessors). I'm stuck on Debian12 because they're dropping 32bit support after that.
I don't really use it to "self-host" other than as a file server for backups and Pihole.
Not sure if that's your case as well, but I remember that there was an issue with Intel Bay Trail tablets where the BIOS/UEFI was 32bit but the CPU could support 64bit OS just fine. You just need to get a special bootloader that will boot 64bit Linux kernel from a 32bit UEFI (which is not normally supported)
Here's one reference https://github.com/dmotte/misc/blob/main/knowledge/linux-x64-grub-uefi-32bit/README.md - it should be possible for you to use a 64bit Debian, but you'll need to get your hands dirty.
I've got proxmox on a pair of atoms.
I’ve got a pi zero w doing shairport-sync https://github.com/mikebrady/shairport-sync , which makes the pi pretend to be an AirPlay receiver. I combine it with the cheapest DAC I can get (used to be Adafruit before they ditched theirs sadly, now it’s https://shop.pimoroni.com/products/audio-dac-shim-line-out ) and bam old speakers are airplay compatible. The Pi is on Trixie and everything.
It’s fantastic that it can do the airplay2 and everything without skipping a beat. Great coding from the dev of it (Mike Brady)!
Started playing with some riscv32 microcontrollers.
2011 MiniPC. I dont use it for anything but a testground
Also running some things in a pi zero w. It's starting to get a little processing limited so I might add a second and split some things off. Pihole, stats page I wrote to help me track stuff, those sorts of things
Did you consider doing the "mount a small monitor" style stats dashboard in your home?
This is more for like rating movies I've watched and books I've read, not calories or weight or anything. It's not updating often enough for a monitor and it's accessible from anywhere so I can pull it up on my phone at any time.

I occasionally spin up Octoprint, and Klipper, on a Pi Zero W.
