Home Automation Progress

An update since last week.

I decided I’d like to keep my CurrentCost netsmart pro posting electricity consumption data to pachube so spliced into the cable to see if I could pickup on the serial data using my home automation hub without disrupting communication between the enviR (CC128) and the bridge.

Taking the leftmost pin of the two connectors with the notch/clip facing downwards the pins are joined as so:

RJ45 -> RJ11
1 -> 1 (Yellow)
4 -> 2 (White)
7 -> 3 (Blue)
8 -> (White)

Rather annoying that they used white for 2 of the cores! On my USB serial cable for the enviR the pinout was as so:

RJ45
4 (Red) -> Spliced into White (pin2)
7 (Green) -> Spliced into Blue
8 (Yellow) -> Spliced into White (pin8)

After hooking the bridge, enviR and usb up to the laptop I could see data coming in over through the serial port- voila!

I punched the CurrentCost details into the hah web interface:

Then configured the extra data streams to pachube:

Just waiting for a few hours for some data but it appears to be flowing in nicely:

I took delivery of the two water meters today- just waiting for a friend to help me fit them and my additional jeenodes to arrives so I can get the data into the hah!

The crazy looking squid thing is the cheapest usb hub I could find to allow me to plug both the jeelink and currentcost enviR into the hah at the same time- hideous but does the job :)

Further to my post earlier today i’ve found that Current Cost will shortly be offering IAMs (Individual Appliance Monitors) which look to start at around £15.00 (or in packs of 3, starting at £30) – http://www.electricity-monitor.com/wireless-energy-monitors-current-cost-c-37_57.html – with a maximum of 9 attached to a single EnviR. I really like the idea of trying to hook one of these up in each room then maybe have a dedicated one for the A/V cabinet, server rack, and maybe a few of the kitchen appliances?

I eagerly await delivery of the Current Cost Bridge so I can find out if it will indeed feed Google Powermeter and then see if it will pass details of the inidividual appliances or only the total.

I came across a few other sites that i’ll be doing quite a bit of reading on over the coming days:
http://www.smarthome.com/ – US store but hopefully i’ll find some products on there which are available over here or at least get me on the right track
