So I’ve neglected the whole energy monitoring interest for a few months but spotted the new CurrentCost Individual Appliance Monitors (IAMs) are finally available (http://www.ebay.co.uk/itm/Current-Cost-IAM-Pack-1-UK-Version-Only-/170673700726?pt=UK_AudioElectronicsVideo_Video_TelevisionSetTopBoxes&hash=item27bcf1ff76) so ordered a few and started playing again.
In addition to monitoring overall household consumption I now have the fridge, servers and living room a/v equipment each giving their own power readings BUT these are not currently posted to the internet using my original CurrentCost bridge. After doing a little reading it appears a new bridge has been released now branded as the CurrentCost "NetSmart". You can send off your existing device to be upgraded (presumably a firmware flash): http://currentcost.com/netsmart-upgrade.html or buy new.
£5.99- NetSmart 12 (12 month subscription with up to 3 additional energy data channels)
£7.99- NetSmart 24 (24 month subscription with up to 3 additional energy data channels)
£11.99- NetSmart Pro 12 (12 month subscription with up to 9 additional energy data channels)
£14.99- NetSmart Pro 24 (24 month subscription with up to 9 additional energy data channels)
£34.49- NetSmart 12
£37.49- NetSmart 24
£39.94- NetSmart Pro 12
£45.94- NetSmart Pro 24
I opted for the NetSmart Pro 24. I’ve yet to receive the device but I’ve seen a sneak peak of what to expect on the forum:
The other addition to my existing system I’ve been wanting to see is the ability to monitor gas and hopefully even water consumption. Neither have officially been delivered BUT a new device is available which may help achieve one or both of the aforementioned: Introducting the CurrentCost OptiSmart- http://currentcost.com/product-optismart.html
The OptiSmart can be used as an alternative to the clamp/transmitter that originally shipped with the energy monitor(s) if (and only if) your electricity meter is compatible. The same device can in theory be used to read gas and water meters should they contain a pulsing LED to indicate consumption. Unfortunately, mine do not! However, whilst examine my gas meter (Slumberger R5) I found an RJ11 socket which after some research appears to provide direct connectivity to the pulses! With a bit of luck the lead on the OptiSmart can be modified to plug in to this RJ11 socket. I’ve sent an e-mail to CurrentCost to see if they can confirm this before I order one. If that fails I may try with the CurrentCost development board.
I mentioned in a post a while back that Google were retiring their Powermeter service so I’m still on the lookout for a replacement service (or building something myself).
After a bit of research I discovered CurrentCost are already feeding the energy consumption and temperature to pachube. There is a nice little pachube app which utilizes google’s charting ability:
You can find your feed_id in the http://my.currentcost.com dashboard (on the right side in the devices section):
Unfortunately only a month’s data is currently retained (this may be a limitation with the free pachube account being used to post the monitor data?) and I really want years of data so I can compare same time last year figures etc. The search continues…
I also stumbled across the Home Automation Hub: http://www.homeautomationhub.com/ which is an open source project which involves ref lashing a Livebox to interact with various devices (including the CurrentCost energy monitor). I really like the idea of this as there’s so much more potential for two-way communication and other applications (linking in nicely with some of my other long term goals) but at the moment I’m going to shy away from it on account of the language being new to me and the apparent lack of current community support.
Expect another update once the NetSmart device comes through and potentially after a start logging gas consumption!
