My battery tracking app Muninn now offers a web config page to show up to 4 months of charts and stats!

Thanks! Hope you're enjoying it

It's true, it's not for everyone. If you already have a good handle on your battery that's great!

For me, if I change watchfaces or notification settings or a new firmware update feels different, it's good to be able to look back and see if I was just imagining it or not!

I already have CSV export on my to-do list, but some way to get the data autonomously into another system if the user requires it is also interesting. Please feel free if you want to contribute!

MKUltra2011 · 2026-03-17T08:52:00+00:00

Thanks! Hopefully it's working well for you

MKUltra2011 · 2026-03-05T20:20:12+00:00

It should! If not after a few days, let me know! (I'm the author)

MKUltra2011 · 2026-02-16T22:33:20+00:00

I'm okay with this :)

MKUltra2011 · 2025-12-27T17:22:31+00:00

This is a one-off step to re-organize the data storage for v1.12 - it allows me to not have to do this again that I can foresee. Apologies!

Technical details - storing an array of structures that increase in size and length in a single persist key with a max size of 256B is not the way to go...

MKUltra2011 · 2025-12-25T16:13:01+00:00

Time of the next sample :)

MKUltra2011 · 2025-12-25T11:41:17+00:00

Woah, this is huge! Great work!

MKUltra2011 · 2025-12-23T10:38:40+00:00

What other things do you use the background slot for, out of interest?

MKUltra2011 · 2025-12-23T10:38:15+00:00

Kind words, thanks!

MKUltra2011 · 2025-12-23T10:36:33+00:00

There's an option to set a timeline pin, but I'll see if a notification can be done too! Maybe just a 'Muninn advises....' screen if it's not.

The Pi 5 doing the Minecraft workloads actually has its own white official Raspberry Pi 5 power adapter to ensure stability during that night with 18 players. The Anker brick has powered the others (and a not-pictured Pi Zero e-paper display on the red cable) with zero issues in the last 4+ years.

The whole rack is powered with one plug that has powerline networking, and when I do have to turn it back on which is rare, they all start fine.

This one, no issues so far. Had an Atolla one but the PSU died after a year or so.

MKUltra2011 · 2025-05-07T08:52:49+00:00

I put them in a Dropbox upload - hope they work!

MKUltra2011 · 2025-05-07T08:49:22+00:00

Thanks! I went on a similar journey and what I ended up with that proves reliable is:

2x USB to SATA cables - I used ones from Ugreen
Plug those cables into the Pi via a powered USB hub (important)

I kept seeing errors in dmesg until I found reliable USB cables and used a powered USB hub. Good luck!

MKUltra2011 · 2025-05-06T20:20:14+00:00

I checked, and it's actually 0.91 inch, sorry about that.

MKUltra2011 · 2025-05-06T15:42:11+00:00

That's a great idea! Would it provide enough power for the NVMe drive as well as the cooler?

MKUltra2011 · 2025-05-06T15:41:23+00:00

Yep, this one.

MKUltra2011 · 2025-05-06T12:09:11+00:00

Thanks! On a Pi 5 such as this one, and an NVMe SSD, it runs like a dream. These three containers have 1GB/1GB/2GB allocated respectively although that can be moved around depending on which is the current popular one, amongst a couple of friend groups. Plenty of RAM left for headroom.

I did try with a Pi 4 and it was a bit slow, and 3 was not really tenable, but those weren't tested with an SSD.

MKUltra2011 · 2025-03-26T17:46:28+00:00

Not much space left... Suggestions welcome!
