  • Got myself some energy monitoring Zigbee plugs and made an interesting discovery

  • No idea. I would imagine it does, but that's something I'll need to check.

  • Very cool! However, my house is a rental, so any monitoring equipment has to be somewhat non-invasive.

    Edit: it helps if I actually look at the product before spouting nonsense... Looks promising.

  • No idea, honestly, it's just the default settings. I haven't really had any time to tinker and optimize it to my liking for a while.

  • The PC was drawing ~90W. All solid state, no spinning rust. Lots of fans though, since it's air-cooled. Not entirely sure what was causing the draw, but it's definitely something I want to investigate at some point.

  • Yeah... I know. 🙃

  • Yeah, anything Zigbee needs a hub of some sort that interfaces with the server. Zigbee is a mesh-like network of its own - it doesn't use wifi or Bluetooth or anything.

    I bought Nabu Casa's Connect ZBT-1 dongle; it's like $35 and plugs directly into the HA server. Super simple to configure as well, since HAOS detects it automatically. Plus, the smart plugs act as routers, so as long as there is a path of router-enabled devices that can see each other all the way to the dongle on the server, you shouldn't need anything else.

  • Yep, it's awesome. We got it for $300 from Costco to supplement the smaller chest freezer, and it's been an absolute godsend.

  • One is a smaller chest freezer, about 3 feet tall, probably 6 or 7 cubic feet if I had to guess. The other is a Hamilton Beach upright freezer from Costco. Both are full, so that helps with keeping them cold.

  • I know they're gonna be a power suck lol. Three mini PCs, a SFF PC, 4-bay hard drive docking station, 8-port switch, and a RPi0w... Hoping for a max of 200W, but I suppose we'll see what happens 🫤

  • The PC itself was drawing ~90 watts. The current draw right now - dual 1080p monitors, HA server, a 5-port switch, and a couple other small things - is about 12 watts. Desk power measurement is the yellow line, freezers are the blue line.

  • Right now I just run dual 1080p. I plan on upgrading to a 120Hz+ 1440p ultrawide at some point, but priorities... My entire desk setup is currently consuming 12 watts with the PC shut off. That's ~90W just from the PC.

  • Perfect, I don't need to run the fans anymore!

    Seriously though - we have 5 kids, and feeding the little shits is expensive, so we freeze a lot of things for storage. I thought for certain the freezers would be power hogs compared to an idling PC, but I was very surprised to be proven wrong.

    Next up... Measuring my server cluster 😬

    Hard drive recommendations

  • I have a couple 7 year-old EFRX WD Reds. Bought them new, before the whole SMR vs CMR issue came about. No issues. Solid drives.

  • How reliable/realistic is to use a laptop as a remote file backup server?

    Jump

  • Good point, those are nice to have. Most of my cluster has vPro capabilities, so I can just log in remotely regardless of the OS's condition.

  • That's actually a thing some people do, usually with IFTTT or Home Assistant.

  • Quickly transferring files between PC and phone

    Jump

  • FX File Explorer has a local web-access feature. Start it on your phone and access via local IP, then just turn it off when you're done.

    Don't use on public wifi, it's http-only.

  • LiPo batteries should be stored at 3.7V/cell. That's basically ~50% capacity (fully charged is ~4.2V/cell). I have several LiPo cells for my RC stuff, some nearing 10 years old, that are still perfectly usable because of this storage method.

  • tlp has more features available for Thinkpads, specifically, so there's that. I'm thinking more of a laptop form factor but built as a portable server, with the battery specifically designed to be a secondary power source (like a UPS) instead of the primary power source.

    Of course something like that would be incredibly niche, so it makes sense that it's not really a thing.
