I blogged previously about replacing one of my switches with something a little smaller, quieter, lighter and greener: https://tickett.wordpress.com/2011/12/29/a-few-small-updates/ this was all part of a pretty big rewiring of the network and relocation of the A/V equipment.
All of the devices were in a cabinet in the corner of the living room:
But now I wanted to add the new switch and relocate into the utility room adjacent:
And re-run the wires a little differently (I’d previously used existing holes to get upstairs):
I’ve already pulled most of the equipment out of the cabinet and the cables just keep on coming:
The previous excess cable "neatly" spooled behind the cabinet:
Some hours later- a little progress:
Now upstairs. You can see the grey "conduit" I ran alongside the copper pipes with the existing cables:
Here’s the new hole in the ceiling:
And in the floor to allow cables to be pulled without lifting the floor:
Now the carpet’s back down and the cupboards are back in place:
First few lengths of Cat5e pulled through for 2 connections in the master bedroom:
Back downstairs, lots of velcro to tidy things up:
The comms cab starting to take shape (still a mess but I’ve still got a lot to do):
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:
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 :)
I’ve been crimping my own patch leads for an eternity but never bothered introducing a patch panel. Now’s the time… (forgive the slightly poor quality pictures taken with the phone).
The back of the patch panel:
The 4 port RJ45 wall box and 4 cat5e cables. This is the first time I’ve used those velco tie-wraps and they work a treat (although I guess for inside the house depending on how well I hide the cabling, white would be preferable to black):
The excess / slack nicely spooled:
The patch panel patched into the switch:
This is in the garage (aka server room) where I’m just going to have 4 ports for the workbench. I’ve got a small cabinet in the house and a POE switch I’ve yet to hook up…
A comms cabinet, patch panel and some patch leads:
Some cable management and wall sockets:
More cable management, UPS, new router, fibre, and cisco ip phones:
You may’ve also noticed the currentcost IAMs so I will be able to break down my energy consumption at a lower level (currently I can only see overall consumption).
*EDIT* This project has been abandoned in favour of a much larger project home automation hub: https://tickett.wordpress.com/2011/12/05/more-jeenodes-my-home-automation-hub/ which is now successfully logging data to pachube but still a long way to go!
I’ve been trying to find a Weather Station (only really interested in the temperature, wind speed, humidity, rainfall etc would all be bonuses but not necessities) which connects to the LAN so i can access the sensor information from my laptop/pc or office via the internet. My search didn’t come back with much:
-some reasonably priced USB devices but i don’t want to leave a computer connected to it 24/7
-some extortionatly priced network devices which look like they belong on a NASA space station
So i thought i’d take a look at what my options are on building something myself (how hard can it be?! :)
My first thought was- I need a networkable device with a web server that i can “customise” and a device which can bridge between the software and hardware. The devices i found which met these criteria:
-Router (w/ USB): Already runs a customisable o/s (sounds like DD-WRT or Open-WRT are ideal)
-USB Bit Whacker: Adds digital and analogue input/outputs to a computer via a standard USB port (and already proved to be connectable with DD/Open-WRT http://forum.sparkfun.com/viewtopic.php?p=44501 and http://forum.sparkfun.com/viewtopic.php?p=44501)
But after further research i stumbled across PIC WEB Server (http://www.coolcomponents.co.uk/catalog/product_info.php?products_id=41) which appears to be a PIC board with an ethernet (rj45) connection and built-in tcp/ip stack and web-server.
Anyway- i still have a lot of research to do before i know exactly what i need to start building my device but i’ve ordered a PICKit3, some breadboards, PIC chips and various other components to start learning!
