The buzz
There’s a bit of a buzz going on at work at the moment – a bunch of us from “the Hursley crowd” have started playing with Current Cost meters. These devices are intended to enable consumers to see exactly what their energy usage is and, hopefully, modify behaviour to save electricity accordingly. The idea, simply, is that it provides real-time information about energy consumption.
Rich, James, Nick and Ian have all written about their Current Cost meters already, amid much twittering and the support of @andysc.
The product
The device itself comes in two parts. The unit that goes inside the house is a wireless LCD display which shows the current usage in watts, the current estimated cost per day assuming that usage is maintained, a bar chart with yesterday’s usage, overall KWH in the past day and month, and the time and temperature. The other half of the device is a somewhat larger and heavier transmitter (shown at the top of the picture, the top of the two black boxes inside our cupboard) which sits next to the electricity meter, with a clip that gently attaches around the cable (you can see that hanging off the cable at the bottom of the picture). The product is completely non-invasive and it’s incredibly easy for anyone to install: there’s no rewiring, just a clip. I was extremely impressed. It “just worked”.
Update: I should point out, given some comments, that we’re using an early batch of the meters and I’m not certain when they will be generally available.
Update: Roo points out that Eco Gadget Shop have them for sale to consumers, minus data cable.
The impact
One of the other features of the device is that it can be plugged in to a computer, and the data can then be captured and analysed over time. We are using some homebrew software to do this, pulling the data from the serial port (most of the meters use 9600 baud, it turns out that mine is set to 2400 for some reason).
It’s kind of scary to see some of the spikes in the graph, and just watching this has certainly made me adjust my behaviour in terms of switching things off and unplugging chargers and so on when they are not in use. We’ve all got our meters hooked up via a Microbroker, and this has been my first opportunity to really play around with MQTT technology… I’ve obviously been aware of it for a very long time, but it’s nice to have something tangible to hack around with. It has also led me into a bunch of interesting discussions about home automation, tweetjects and low-power servers. Fascinating stuff.
The ideas
I have a bunch of thoughts about this. I have it hooked up to an old Linux box, but I’ve also successfully attached it to my Macbook Pro and a Windows Thinkpad. Currently the software is sending the MQTT data to a Microbroker and a Java app is drawing the graph shown above, but it would be fairly straightforward, for example, to squirrel the data locally and do some interesting analytics using Project Zero (aka WebSphere sMash) and some AJAX-y Google Chart goodness. I can also capture ambient temperature over time. It’s all just a matter of finding the hacking opportunity!

in reply to Snoopy • • •Making them private is absolute idiotic. People participating in a discussion forum are willing to engage in a public conversation, if you are not willing to respond in public, then don't respond at all. And if you think that the original comment is in bad faith or harmful to the community, report it and move on.
"Votes" are not real votes. It's just a terrible misnomer for "Liking" and "Disliking". I think we should get rid of votes altogether and use the real vocabulary.
I'd also would like a system where users could define their own scoring algorithm, and I would like to assign different weights depending on the person and the topic/community. I for one think that downvotes (dislikes) should only be counted if you are a member of the community and if you have made a positive contribution to the discussion.
I'd like to be able to follow people just to see what they are liking/commenting on. Also, given that this is a discussion forum, I wonder whether we could build a wiki-like system where people could annotate parts of a comment/post and challenge/elaborate/investigate specific parts of an statement. This could be used either for a "Change My View" style of discussion or even full-on adversarial collaboration projects.

in reply to Snoopy • • •Public. Lots of downvotes is information that could indicate that the commenter is lying, or just saying something unpopular. But either way, it's information. Before youtube started hiding downvotes, it was easy to tell that a video was full of it based on downvotes. Now clickbait dominates the platform.
No. I agree that the slashdot method with more than just upvote/downvote is better. In a perfect world I imagine we could have every emoji be a reaction option, and then you could sort by putting an emoji in a bar at the top. In reality I imagine this would be a challenge from a backend perspective, but maybe like the top 5 or 10 emoji reactions could be an option for selection.
I'll do the opposite and say - please do not remove downvotes like Twitter/Bluesky/mastodon etc. Downvotes are super important. People need to be able to boo, the only place people aren't allowed to boo are in church or at cult rallies. And that's why those platforms are especially bad for misinformation, hyperbole, and overall depravity.
Remove all as a forced/default option on the main page. Back in the day before reddit had r/all, communities were much more diverse and niche, and this helped separate communities flourish in their own way. When r/all was added, the content started to resemble twitter, if not just becoming screenshots of twitter, on just about every sub. This actually improves discoverability because it would force users to branch out and look at subs instead of just looking at what's on all.
