I wrote myself a smol tool for analyzing daily energy usage patterns (electricity/gas). Basically I'm reading out my (non-smart) meters every night and recording the absolute values in a table, annotating them with tags (think "vacuumcleaner" or "coldday" e.g.) so I can in hindsight make sense of notable patterns when they emerge. I decided to expand it just a little to make it usable for others (will be ready end of november I estimate), here's what to expect: Client-side browser tool (a tiny webpage, all computation happens on your device). Edit mode which is basically a spreadsheet for entering all values. Export json so you can keep your data on your machine (you'll have to actually :)) - and so you can add data points offline in your texteditor (I might add a csv-ish format too). Import json so you can import your records back into the tool to visualize/analyze them. If you want you can then also download the tool to your computer and run it 100% from there. And that's it. Screenshots from work in progress attached. :unwanted_ok:


My thinking here btw.: By adding a small, dedicated spreadsheet editor in the tool, the technical barrier to using the tool gets lowered to having to know 1) how to use a website 2) how to download a file from a website 3) how to find and re-upload that file to that website (note that the "JSON" stuff still needs less cryptic labeling then of course to be accessible!), I think this might actually be a reasonable offering also for non-tech folks while still upholding a no-maintenance, no-nonsense lotech approach? (let's see, and let me know if you have any thoughts on that! :))
