    At this point, I’ve found a carrier that does 10GB for $17 a SIM (and I could probably get away with less data for cheaper), and I’d be fine with that. I have several rPis that act as hubs taking in LoRa data from things like solar pumps, water bowls and bins, but backhauling to the central server over LoRa is a pain, and we don’t have LoS to all of them so using radio bridges is spotty. Some sites are 10km away over hills. And moving everything to MQTT would make my life easier than my custom BS programming that has devices talking to each other directly.

    We don’t generally have issues with phones and where I do, I can probably put up an antenna if the dongle has an external port, or I’m willing to spend extra $$ for an uplink with external. I currently have a Microhard LTE-CAT4 that I use on one remote site that seems to get good reception, but that unit is pretty pricy and I have to fart around with network cables and power when I could just be plugging in a USB dongle.

    I see a lot of cheap ones on Amazon, but I was hoping someone had a common Linux specific model they know works, because most of those look pretty janky.



















  • VMs under KVM are pretty much bare metal and Proxmox doesn’t use much for resources itself, it’s basically a headless Debian with a webserver interface to do all the KVM stuff.

    Proxmox, especially if you use ZFS for the VM datastore, makes a home lab so much easier to revert, backup and deploy/clone VMs and LXCs. I highly recommend it if you’re just starting out. Once you wrap your head around it, it gets out of the way and lets you just tinker with your projects, and not have to manually do everything in VirtManager or at the command line.

    Combined with Proxmox Backup Server, it’s a production ready hypervisor for anything you decide to keep. Also, the HA features work well enough that I had my main routing OPNsense VM jump between nodes when the primary node lost a drive, and I didn’t notice for a week, it was that seamless.
