Almost

Now I get "Feed ID or some other parameter does not exist." I updated the Feed ID in both files for the new key pair so I'll see if I missed something else

EDIT: I am seeing feeds in the COSM API Debugger. The Response Body contains "I'm sorry we are unable to find the feed you are looking for."

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

I think I need to learn more about how this COSM works....

I had my own issues with cosm on an earlier project, I'm going to look at using GNUPLOT with local data.

This takes nothing away from the good work redbenn has done, it's solid. I just prefer keeping things in-house.

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)?

Depends on how complicated you want to make it. Looking at the Relay Output Example, it seems to me that you could put the code in the loop() into a function that's called in the Teensy 3.0 loop() replacing the

Code:

Input = analogRead(0);

with

Code:

Input = (double) chip[x].status;

and

Code:

if(Output > now - windowStartTime) digitalWrite(RelayPin,HIGH);
  else digitalWrite(RelayPin,LOW);

with

Code:

if(Output > now - windowStartTime) setSwitchState(x,ds2406PIOAoff);
  else setSwitchState(x,ds2406PIOAon);

Just as a test you could hard code the values for the thermometer and switch, put all of the setup in the setup() and let it rip.

While redbenn's version of graphing software using COSM works just fine, I prefer to keep my info in-house.

To that end, I created a database table to track enabled actions and display the output on a local web page.

First I created a new table in phpmyadmin for the teensypi database:

Code:

CREATE TABLE IF NOT EXISTS `actionGraph` (
  `id` int(11) NOT NULL,
  `time` bigint(20) NOT NULL,
  `temp` int(11) NOT NULL,
  `tcTemp` int(11) NOT NULL,
  `tcSwitch` enum('ON','OFF','NONE') NOT NULL,
  `thTemp` int(11) NOT NULL,
  `thSwitch` enum('ON','OFF','NONE') NOT NULL,
  KEY `id` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

and installed GnuPlot

Code:

sudo apt-get install gnuplot

Then I created the files:
graphActions.php
plotData.php

updated:
updateActionStatusWithMySQL.php

and downloaded:
PHP_GnuPlot.php

All of the code is available at my github directory

I then added a cron entry:

Code:

* * * * * /usr/bin/php /var/www/htdocs/graphActions.php

To update the action status to the MySQL table once a minute.

Now when I go to my Action Status page:

You will see a "GRAPH" button. Clicking on that will greate a graph:

That will show you the temperature and setpoints. If you change your trigger points, the graph will reflect that. I plan to add some viewing granularity, but I think that's enough for today.
