Mindless Fluffiness

I wanted to publish some sensor data from my house up to pachube.

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:
