I’m using a Shelly Plus Plug S smart plug to measure the power usage of my homelab. I added it as a device in Home Assistant — and the power readings began! Kind of…

Within a few days; I noticed something strange with the graph history — there were long periods of time where the graph was completely flat. Logging into the Shelly web interface, I could see the watt reading changing — without this being reflected in Home Assistant.

Two years ago we dug and laid three conduits from the house to the garage, and from the garage to the shed. Primarily to get more power to the garage — and any power to the shed.

I used the opportunity to put in an additional conduit for fiber, and lots of conduits from the main switch board down into the basement.

I recently got a new laptop, (well — not new, but new to me), a HP ZBook 15 G5. After installing Arch Linux and the i3 wm I spend some time setting up power management, suspend on idle, and figuring out the state of the battery.

With the electricity prices we’ve seen in Europe lately — I wanted to see if we could reduce our energy consumption. I’m specifically looking at “wasted” energy, meaning usage we can reduce without even noticing it.

I’ve already written about my PDU suddenly dying — and in that post I explained that I was going to do some changes to the homelab power layout. It’s time to do those changes 🙂
