Just a quick update, since the last time I mentioned our system the
dashboard was still rather rough. Since then I have added a better UI,
exposed the live data more, added little JQuery graphs along with
history and CSV export. All that in 1 week worth of evenings - isn't
Please check out the dashboard and drop me an email if your company
wants to cut its power bill by 10 - 20% through monitoring its power usage:
Could someone add me to the projects page? You could use the above link
and the following text
Gridspy - Live power monitoring and analysis
The Nexus costs $685 USD, monitors 3 different circuits and uplinks
collected data to the site via ethernet. We also have a wireless device
called the Gridspy that costs $495 USD, monitors 6 circuits (or a
variety of other things) and talks to the Nexus wirelessly to upload data.
More info on the devices here:
Any comments, questions or suggestions are welcome.
> My previous email:
> Hi Everyone
> I would like to introduce my project for the
> http://twistedmatrix.com/trac/wiki/ProjectsUsingTwisted page. We use
> twisted as the central server that talks to many power measurement
> sensors in the field.
> Gridspy provides you with an interactive view of resource usage in
> your building. It gives you hard data on your consumption patterns and
> helps you to make informed decisions.
> The Gridspy allows you to access and monitor your consumption patterns
> in real-time using a standard web browser on your PC, laptop or mobile
> phone. The data is presented in high resolution and updated each
> second as you watch. The moment a light is turned on in your house,
> you can see the change on your Gridspy dashboard from across the room
> or across the planet.
> Our homepage is here http://www.gridspy.co.nz/
> a running demo is here http://your.gridspy.co.nz/powertech
> And you can read more about the role of our twisted backend here:
> ... The nexus then collects those sensor samples from the nearby
> Gridspies, bundles it up with its own data and uploads it to our
> central servers. To collect the data we use a custom application
> written using the excellent Twisted framework
> <http://twistedmatrix.com/>. Every single reading gets instant
> attention: it is evaluated for real-time events, queued to be stored
> in the database and finally forwarded to watching dashboard users.
> Processing the data stream live on the server opens up many exciting
> possible features that I look forward to discussing in future blog
> posts. By the time that the sample reaches the server, it is about 0.2
> seconds old. ...
> It has been a great framework to work with. My sincere thanks goes to
> everyone who has ever contributed to this project. Job very well done!
