Gilbern, great lightweight fibreglass bodied "sports" cars from Wales...

I started with a Dell Wyze 5070 from eBay. I put a 1Tb M2 sata in it, and 32Gb of RAM. Be warned it's really picky about RAM type. After a while I added 2 more, for testing and to spread the load a bit. I also added a proxmox backup server. I like the little boxes as they run at about 15W each.

If I was doing it again, I'd try and find a lowish power box that wasn't so picky on RAM, and also look at something with a 10GbE port so I could run ceph for some shared storage - but that pushed the price up...

HTH

I have a rainwater tank, and I use an esp32 (nodemcu) flashed with Tasmota, and a waterproof ultrasonic sensor to measure water level.

Yes

True, but I really appreciate that someone is doing it. (It’s far beyond my capabilities…)

Or use this…

I’m just running them independently. Although the proxmox helper scripts automate the creation of a load of bits that I use. https://community-scripts.github.io/ProxmoxVE/

I don’t run much, just a Debian-vm, Unifi docker, Jellyfin and Jellyseer (and some *arr) apps.

I grabbed a cheap Dell Wyze from eBay, then stuck proxmox on it, then Home Assistant in a VM. Works beautifully, plus I can run other VMs and containers. Plus snapshots etc. It runs at 5w idle and 15w under load.

Hate to say it, but unless you go for air-con, just a standard pedestal fan works way better than the evaporative coolers.

Just wish there was an iOS app…
