Wowza! Incandescent lights use ALL the electrons. This is five sets of twenty-five C9 lights, totaling one-hundred, twenty-five C9 bulbs. The power floats around 850 watts when the sets are all on.

I realized I had an unused PyPortal around, so yesterday evening I quickly hacked together a (solar, battery, house) power display. Pushing the data to it using MQTT.

Obviously want to make it prettier and include some more values on it, but quite functional as a first test.

The circuitpython doc is still as hard to search as before, it could use a browsable list of libraries

Picture of a bare LCD on a PCB showing 4 horizontal bars
Line 1 has a 71% fill of red (a bug, should be green) and 71% to the left of it, it is the battery charge state.
Line 2 is actually 2 bars next to each other, the left for discharge and the right for charge, which is currently showing some green fill.
Line 3 is a partial green bar indicating solar production.
Line 4 is a partial red bar showing house power consumption.

Since putting some #PowerMonitoring in I'm quite surprised by how much power the dishwasher and/or washing machine use...

measure power consumption on desktop/server machines
Install the excellent scaphandre github.com/hubblo-org/scaphand

On Fedora 42
- install rust/cargo via rustup
- install openssl-devel package
- run "cargo --disable-default-features" to avoid an issue with the riemann client
Note: if you need support for prometheus or json enable it again with '--features "json prometheus"'

I'm trying to integrate #powermonitoring into my #homeassistant instance. I'm building an #homessistantglow : https://glow-energy.io/docs/resources/schematics/
Now, my meter has two LEDS: one is called Ra and the other Rr. The meter's manual don't explain the difference between the two. Anyone knows which one should I use for the reading?

I have strategically placed energy monitoring that is now integrated into Home Assistant. Mostly it's to determine things I can run from the car in an emergency, and be able to monitor it.

Also, interestingly, it's prompted me to finally look at retiring/replacing an old home server that might be a tad power hungry.

Migrating is going to be a...process...

Live Energy Monitor Helps Plan Power-Hungry Appliance Use

There are a lot of good reasons to have a better understanding of one's household power use, and that is especially true for those that do their own solar power collection. For example, [Frederick] determined that it would be more efficient to use large appliances (like a dishwasher or washing machine) when there was excess solar power available, but the challenge was in accessing the right data in a convenient way. His Raspberry Pi-based live energy monitor was the solution, because it uses an LED matrix to display live energy data that can be consulted at a glance.

Interestingly, this project isn 't about hacking the power meter. What this project is really about is conveniently accessing that data when and where it is best needed. [Frederick] has a digital power and gas meter with the ability to accept a small wireless dongle. That dongle allows a mobile phone app to monitor power usage, including whether power is being taken from or exported to the grid.

Since [Frederick] didn't want to have to constantly consult his mobile phone, a Raspberry Pi using a Pimoroni Unicorn HAT HD acts as a glanceable display. His Python script polls the power meter directly over WiFi, then creates a live display of power usage: one LED for every 250 W of power, with the top half of the display being power used, and the bottom half representing power exported to the grid. Now the decision of when to turn on which appliances for maximum efficiency is much easier, not by automating the appliances themselves, but simply by displaying data where it needs to be seen. (This kind of thing, incidentally, is exactly the idea behind the Rethink Displays challenge of the 2021 Hackaday Prize.)

As for those of us without a digital power meter that makes it easy for residents to access power data? It turns out there is no reason a power meter's wireless service interface can't be sniffed with RTL-SDR.
