Starting to build out the full electronics. I picked up a terminal strip for my 5V/5A DC power supply. This will power the TeensyPi and the 8 device relay board. I also bought an additional Arduino shield (think it was for a Mega) to wire the switch and temp probe circuits. Right now I just...

If I wanted to test out using the Arduino PID library in place of the actions, would I need to modify void softSerialProcess() and void updateChipStatus(int x)?

The feed id is just a numerical value, make sure you don't have quotes around it in the code.

Do you have the correct API Key? Check on cosm your keys. You may need to create a new one that will allow you to reade/update/create/delete all your feeds.

try this code on the update $pachube->_debugStatus($pachube->updateDatastream("csv", $feed, $cosmid, $temp)); instead of $pachube->updateDatastream("csv", $feed, $cosmid, $temp); This will run a debug on the cosm update.

Ah, found the problem... on the updateNames.php this line if(substr($chipAddress,0,4)=='0x28') { $query2 = "SELECT * FROM cosm where address = '" . $chipAddress . "'"; Should be: if(substr($chipAddress,0,4)=='0x28') { $query2 = "SELECT * FROM...

Is it inserting them the first time, then if you update the names it will insert the same record again? Same address in the ChipID column in the cosm table? Were the cosm feeds created when you updated the names? If so, does anything post to cosm if you access cosm.php directly from your web...

Yes, that could be done as well. We wouldn't want the 0x28 filter for the MySQL table/cosm feed creation. We could then send a 0 or 1 to cosm to track if the switch is on. I will look into adding that later tonight.

Added the Connecting the TeensyPi to Cosm.com to log data guide to TeensyPi.com here: http://www.teensypi.com/cosm/

To create the cronjob to update the cosm feed, we need to update crontab with the timing to run the job, the location of PHP, and the location of our cosm.php file we want to run. For me PHP was located at /usr/bin/php. You can verify yours by typing find php from the command line. To...

Ahh, could have been because I was trying to connect via FTP instead of directly mounting the TeensyPi. I use Transmit on OS X Mountain Lion.

You will also have to modify updateNames.php. This will add the ability to create COSM datafeeds when a new chip is named. I set it up to tie the chip address to the feed as opposed to the chip ID since they will move around IDs, but the address will stay the same. First add references to the...

Next download the COSM (formally known as Pachube) PHP library from here: https://github.com/MunGell/PachubeAPI. Then upload the PachubeAPI.php file to your /var/www/htdocs directory. This will create functions that make it easy to get/post data from/to COSM. Next create a new PHP file in...

I added a table to the MySQL database called cosm. Log into phpmyadmin at http://teensypi.local/phpmyadmin/. Go to the TeensyPi database. Click on the SQL link and paste the following code: CREATE TABLE IF NOT EXISTS `cosm` ( `id` int(6) NOT NULL AUTO_INCREMENT, `chipid` varchar(50) NOT...

This is where I diverged from the Adafruit tutorial, as I know PHP so this was easier for me... You will need the PHP-Curl library installed to post/get from COSM. You may have to install this if it is not already on the Raspberry Pi. To check to see if it is installed, create a new PHP file...

Next was to create an account on COSM which will log the data. I followed this guide from adafruit for the most part. Once you have an account, click the blue button to set up a feed: Select Arduino, and name it, tag it, etc. You will need the API Key from the code generated and...

One of the changes I did was install VSFTPD so I could FTP into the TeensyPi. This allowed me to access the htdocs easier. I did this as [email protected], as that is the owner ove the /var/www folder. I got the instructions from here. Type in "sudo apt-get install vsftpd" and hit...

Relay came today, I hooked it up to 2 of my switches which were in an action. Everything worked great, when the switch activated, it activated the relay. Also got COSM working with a PHP cronjob. Waiting on my heat tape and solenoids, then going to test out the actions to see how they dial...

That sounds like the easiest way to implement, I am going to create a cron job that will run a similar query to updateStatus.php that will post the results to COSM.

Had a similar issue this morning as I did previously where my sensors stopped updating. Happened after having it unplugged for a day. The LED on the Teensy board was pretty dull, I am wondering if it was trying to process too much after reboot? I am reloading everything again, I don't think...
