You can find the software at: http://fluffyhome.googlecode.com/svn/trunk/arduino/PachubeClientWithDHCP.cpp

First you will need to install the DHCP library from: http://blog.jordanterrell.com/post/Arduino-DHCP-Library-Version-03.aspx

And then install the 1-wire library and Dallas Temperature Control library which are both found inside the the zip file at: http://milesburton.com/wiki/index.php?title=Dallas_Temperature_Control_Library#Download

At this point you need to have an account on Pachube and create a manual update feed. The first data stream will be used for the temperature. Next you need to go in to the PachubeClientWithDHCP.cpp file and edit the API KEY and feed ID to match yours. You don’t really need to change anything else. If you have other Arduino with fake MAC addresses, you might want to check this one does not conflict.

The 1-wire bus is connected to Digital IO pin 8 on the Arduino and pulled high to the 5v power with a 4K ohm resistor. Pin 1 of the DS18S20 is connected to ground, pin 2 to the 1-wire bus, and pin 3 to 5v power. (Yah, I know about parasitic power but I have power so I used it).

Compile and install the software, connect up the Ethernet, and start it. That’s about it.

I wrote a python program that you can find at http://fluffyhome.googlecode.com/svn/trunk/indigo/graphVars.py that goes through the Indigo database (you can see my preivios posts for how temperature data gets into this database), looks for all the changes to the mainTemp variable, and creates an HTML web page that calls googles charts to produce a graph.

An example graph is

I’m using a venstar T1900 thermostat (http://venstar.com) along with insteon module from SmartLabs (http://www.smartlabsinc.com) over to a INSTEON controller connected to the Indigo software from http://www.perceptiveautomation.com.The first step is to get the temperature from the thermostat into the database on the system running the Indigo software. I do that with using a “Time/Date Action” in the Indigo software that runs ever 10 minutes and has an action type of “Execute AppleScript”. I use the following embedded script

All the code following in this blog post is license under the simplified BSD license (see http://www.opensource.org/licenses/bsd-license.php) if you want to use it.

set myThermostatName to “MainThermo” # you can find the name to put here in the Device screen in Indigo

tell application “IndigoServer”

set mainThermoDev to device myThermostatName

set myTemp to temperatures of mainThermoDev

set value of variable “mainTemp” to myTemp

set myHumidity to humidities of mainThermoDev

set value of variable “mainHumidity” to myHumidity

end tell

This causes the variables to be updated with the values from the thermostat. Any time they change, they get written to the database.

Next I have a shell script program that reads values out of the databases and puts them in weird format that MRTG wants. This script looks like

#!/bin/csh

setenv VAL ` sqlite3 -csv /Library/Application\ Support/Perceptive\ Automation/Indigo\ 4/IndigoSqlClient/sqlite_db ” SELECT var_value FROM variable_history WHERE var_name=’$1’ ORDER BY ts DESC LIMIT 1 ; ” `

if ( $VAL == false ) then

echo 0

else if ( $VAL == true ) then

echo 100

else

echo $VAL

endif

echo 0

echo 0

echo $1

exit 0

I call this script from the MRTG. My MRTG configuration has an entry that looks like

Target[mHumidity]: `/Library/WebServer/mrtg/scripts/mrtgGetVar.sh mainHumidity`

Options[mHumidity]: nopercent,growright,nobanner,integer,gauge,noo

Title[mHumidity]: Main Humidity

PageTop[mHumidity]: <h1>Main Humidity</h1>

YLegend[mHumidity]: Percent

ShortLegend[mHumidity]: %

LegendI[mHumidity]: Humidity

LegendO[mHumidity]: Humidity Index

MaxBytes[mHumidity]: 100

And the end result is a graph like

I also have some triggers that happen when my office ligth goes on or off and set a variable called COfficeLight to true or false. The MRTG config looks like:

Target[cOffLight]: `/Library/WebServer/mrtg/scripts/mrtgGetVar.sh COfficeLights`

Options[cOffLight]: nopercent,growright,nobanner,integer,gauge,noo

Title[cOffLight]: C Office Lights

PageTop[cOffLight]: <h1>C Office Lights</h1>

YLegend[cOffLight]: TBD1

ShortLegend[cOffLight]: TBD2

LegendI[cOffLight]: TBD3

LegendO[cOffLight]: TBD4

MaxBytes[cOffLight]: 110

Produces a graph like

Finally I have a python program to get weather information. This program requires the wether API for python to be installed (see http://code.google.com/p/python-weather-api/ ). The python program looks like

#!/usr/bin/env python

import pywapi

import string

import optparse

import sys

def main():

global options

optionParser = optparse.OptionParser(version=”%prog 0.1”,

description=”Get weather in format approperate for MRTG”,

usage=”%prog [options] city”)

optionParser.add_option(‘—verbose’,’-v’,action=’store_true’)

optionParser.add_option(‘—metric’,’-m’,

action=’store_true’,

help=”use metric values. Default is imperial”)

optionParser.add_option(‘—humidity’,”,

action=’store_true’,

help=”Return relative humidity instead of temperature.”)

options, arguments = optionParser.parse_args()

if ( len(arguments) != 1 ):

optionParser.error(“Must provide one city name such as ‘Calgary,AB’ “)

if options.verbose:

print “City is ” + arguments[0]

result = pywapi.get_weather_from_google( arguments[0] )

if options.humidity:

humRes = result[‘current_conditions’][‘humidity’]

hum = “%s”%humRes

if options.verbose:

print “Raw humidity string is ” + hum

h = int( float( hum.lstrip(“Humidity: “).rstrip(“%”) ) )

if options.verbose:

print “Parsed humidity is %d”%h

print “%d”%h

print 0

print 0

print “OutsideHumidity”

else:

if options.metric:

print result[‘current_conditions’][‘temp_c’]

print 0

print 0

print “OutsideTempCelcius”

else:

print result[‘current_conditions’][‘temp_f’]

print 0

print 0

print “OutsideTempFahrenheit”

return 0

if __name__ == “__main__”:

sys.exit(main())

and I use a MRTG config like:

Target[outsideHumidity]: `/Library/WebServer/mrtg/scripts/mrtgGetWeather.py —humidity “Calgary,AB” `

Options[outsideHumidity]: nopercent,growright,nobanner,integer,gauge,noo

Title[outsideHumidity]: Outside Humidity

PageTop[outsideHumidity]: <h1>Outside Humidity</h1>

YLegend[outsideHumidity]: Percent

ShortLegend[outsideHumidity]: %

LegendI[outsideHumidity]: Humidity

LegendO[outsideHumidity]: Humidity Index

MaxBytes[outsideHumidity]: 100

I used a venstar T1900 thermostat (http://venstar.com) along with insteon module from SmartLabs (http://www.smartlabsinc.com) over to a INSTEON controller connected to the Indigo software from http://www.perceptiveautomation.com.

First you need to create an account on pachube.com and create a new feed with two data streams. The first stream is temperature and second is humidity. Make sure the “Feed Type” is set to manual when you created the feed. From the pachube site, you need to get your API key and the feed ID for the feed you created. In the Indigo software, I created a “Time/Date Action” that runs ever 10 minutes and has an action type of “Execute AppleScript”. I use the following embedded script

The following code is license under the simplified BSD license (see http://www.opensource.org/licenses/bsd-license.php) if you want to use it.

# to use this script, you need to edit the next three lines with your API key, and URL for for your feed, and device name in indigo software for your thermostat

set myPachubeAPIKey to “PUT YOUR KEY HERE”

set myPachubeFeed to “http://www.pachube.com/api/feeds/1234.csv” # change to your key

set myThermostatName to “MainThermo” # you can find the name to put here in the Device screen in Indigo

tell application “IndigoServer”

set mainThermoDev to device myThermostatName

set myTemp to temperatures of mainThermoDev

set value of variable “mainTemp” to myTemp

set myHumidity to humidities of mainThermoDev

set value of variable “mainHumidity” to myHumidity

end tell

try

set myRes to do shell script “curl –max-time 10 –silent –show-error –request PUT –header ‘X-PachubeApiKey:” & myPachubeAPIKey & “‘ –data ‘” & myTemp & “,” & myHumidity & “‘ ” & myPachubeFeed

if myRes is not equal to ” “ then

log “Problem with posting to pachube. curl result is:” & myRes

end if

on error

log “Error execting curl to post to pachube.com: Result was ” & myRes

end try

#log “ran the temp log script temp=” & myTemp & ” humidity=” & myHumidity

You can get a google gadget on a web page to graph your feed by embedding the following code after changing the feedID from 1234 to whatever your feed is.

<script src=”http://www.gmodules.com/ig/ifr?url=http://apps.pachube.com/google_gadget/p.xml&amp;up_feedID=1234&amp;synd=open&amp;w=400&amp;h=300&amp;title=House+Temp&amp;border=http%3A%2F%2Fwww.gmodules.com%2Fig%2Fimages%2F&amp;output=js”></script>

The end result should look something like:

Note in all the following photos, no one is ever wearing any protection on their head. There is a huge demographic range and none of them use head protection.

There are men and women,

And ones where I’m not sure

Thin and Not so Thin

There are old people

There are young people

There black, white, other, and multicolor

But nobody seems to care about the usual drivel about not wearing headphones

Not to mention the use of mobile phones

Or perhaps a little texting while riding

Some idiot with a Canon 5D taking a photo of himself while riding. No doubt not a local.
