Today I’m releasing a first version of the open source JeeMon home monitoring application, along with a demo dataset. Warning: this is an early alpha version – all features and bugs are still likely to change, a lot!
There are builds for Windows (x86), Mac OS X (x86 and ppc), and Linux (x86 + x86_64 + some embedded systems, such as the JeeHub’s MMnet1001 module).
It takes 3 steps to run this demo – there is no installation:
- Get a runtime for your computer from this area
- On Unix-like systems, run this: chmod +x JeeMon-*
- Launch JeeMon
Here is the debug output this generates on my laptop:
And here’s a Windows screenshot with similar output:
Now point your browser to http://localhost:8888/ to see what JeeMon has to offer.
When started for the first time, JeeMon downloads a few extra files from the internet: “Jee-demodata”, “Jee-library”, and “Jee-library.update” (under 2 Mb total). These files are obtained from public servers at Dropbox, I do not track downloads or statistics.
On every subsequent startup, JeeMon looks for updates and refreshes the “Jee-library” file if there is a new version, so by simply starting JeeMon again a few days later you can track its development progress. To disable automatic updates, delete the “Jee-library.update” file.
I’m releasing this code to give you an early glimpse into the Jee Labs kitchen – and to gauge the interest and figure out how to improve JeeMon. If the demo works for you, great. If it doesn’t, you can either try to figure out what the problem is, or delete all the Jee-* files and try again at a later date. The new mailing list announced yesterday is open to anyone wishing to comment and make suggestions.
Let me reiterate that this JeeMon alpha release is for infinitely curious and technically interested people, not for those looking for a finished home energy monitoring solution. Running this JeeMon demo is bound to raise more questions than I can deal with – but it’s all open source, so feel free to explore this as much as you like.
Whatever. Enjoy …
Update – the demo dataset now contains data since 2009-01-01, i.e. a total of over 3 months of readings.
