Just read the Raspberry Pi thread - looking really good.

In the post this morning I got my CISECO EVE http://www.kickstarter.com/projects/ciseco/eve-alpha-raspberry-pi-wireless-development-hardwa which plugs onto the Raspi to give you wireless options a-plenty. I havn't tried it yet but perhaps over the coming hols. Dealing with Linux might take some getting used to but all good fun learning.

At the moment I'm using SolderCore which is a real treat and so much more robust than my previous Arduino based get up: http://www.airsensor.co.uk/component/zoo/item/soldercore-co2-shield-to-cosm-sd-card.html

The code it written in BASIC and is sweetly short/easy to read :-).... all good fun.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9926&Focus=163646#Comment_163646 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=9926&Focus=163646#Comment_163646 Thu, 20 Dec 2012 14:45:39 +0000 SteamyTea Posted By: RoburDealing with Linux might take some getting used to but all good fun learning.Or incredibly frustrating
I may look at Bluetooth as a way to get a keyboard and mouse and transfer files to it.
Though go t it running on the wireless at them moment, can't get it to connect via the Ethernet though. Can ping the router, can use TightVNC across my network (but have no idea how to make it start at bootup) but just can't get it to talk to 'outside'.

Are you trying to connect via a hardwired network, or a wireless network ?

There's a guide to using a hardwired network here http://www.raspberryshake.com/raspberry-pistatic-ip-address/
Getting wireless to work usually involves installing a driver for which-ever dongle you choose. I went for the TP-Link TL-WN725N.

With wireless, I had write an additional script to start the network running because the Pi stops its wireless network connection when the router is switched off. The script runs every hour-or-so to restart the wireless services in the hope that the router has been switched back on.

Let me know if you need any specific advice on getting the Pi to talk to the network.

Friend of mine got the USB WiFi devices for me, would have to check what they are. They work right out the box though.
Over on my RPi thread someone mentioned about a bit of software that can check on scripts running and restart them when they stop. Not had time to play with it yet but will get around to it soon.

Hopefully within the next week. I'm going for a hard wired solution over twisted pair cat5e as the components are cheap.

If u do consider wireless go look at enoceanpi I've specified their products through work and their very good.

Hmm, still over £70 for a switch

This is my bash script which is called from crontab once an hour. It checks for the presence of the wireless network and attempts to start the service only if it has stopped.

#!/bin/bash
#
# If the network is down, try to restart it
#

packets=`ping 192.168.0.1 -c 1 | grep -ic "1 received"`
#echo "${packets} packet(s) recevied from pinging 192.168.0.1"

if [ "${packets}" == "0" ]; then

# network is or was down
#echo "Attempting to restart the network"

cd /etc/init.d
sudo ./networking stop >>/dev/null
sleep 5
sudo ./networking start >>/dev/null

fi

The serial cable came from Amazon "Pi RS232 cable Raspberry Pi Pi Console cable", but it needed a "gender changer" to plug into the Dylos.

If you start the reading script as a daemon, it will monitor that as well.

All the logging is done locally on the Pi. The only thing I use the WiFi for is a weekly ftp session to transfer the log files to a PC.

What I need now is an easy way to convert csv files from the Dylos, into daily graphs.

Sprocket - I did look at GNUplot and it almost does the job, but the axis labels graph becomes quite messy with a whole day's worth of data from the Dylos (one reading every minute). I couldn't figure out how to reduce the number of labels on an axis. Even averaging the readings into 15 minute intervals didn't reduce the clutter.

I have OpenOffice installed at home, and Excel at work. I did plot a graph with these, but it took quite a bit of manual labour. I'd like to be able to automate the production of the graphs.

I'm open to other suggestions - or even some expertise with GNUplot :-)

The GNUplot config file I was using as a template is...
set terminal png
set datafile separator ','
set key autotitle columnhead
set output "DayFiles\Hours_040613.png"
set xlabel "Time"
set ylabel "Particle Count per cubic foot"
set title "6th April 2013"
set xtics nomirror rotate by -90
plot "DayFiles\\Hours_040613.csv" using 1:2 with lines, "" using 1:3 with lines, "" using 1:xticlabels(1)
