Information for using plot.ly:

You have to install the plot.ly python package first. For instruction see https://plot.ly/api/.

Then, in the update_plotly.py file fill in your username and api key!

The plot.ly graph can also be embed in your website by using the following code (just replace the plot.ly link):

#PiTemp

A simple script that monitors your Raspberry Pi's temperature. Check out the Trello Board for this project

##Installation

Before you can start monitoring your Pis temperature in your webbrowser you need to install a webserver with PHP. I use a LAMP setup. Follow one of the many guides like this or this one to setup your Raspberry Pi as a webserver.

If you have git installed on your Raspberry you can easily clone the repo into the webroot of your webserver.

// Example is for apache only. 
// Replace /var/www/ with the webroot of your webserver
cd /var/www
git clone https://github.com/fechu/PiTemp

The next thing to do is to setup cron to execute the monitor.php script every 15 minutes to write down the temperature. You do this by modifing the file /etc/crontab like this:

sudo nano /etc/crontab

Add the following line to the end of the file.

*/15 *  * * *   root    /var/www/PiTemp/monitor.php

This tells cron to execute the script every 15 minutes of an hour. root is the user that executes the script. and /var/www/PiTemp/monitor.php is the script that is executed.

That's it! Now you need to wait for your script to collect the data.

As soon as you can't wait anymore, just open your browser (the computer has to be connected to the same network as the Raspberry Pi) and navigate to http://<Your Pi's IP>/PiTemp.

##Configuration

You can find all configuration options in the config.php file. Have a look at it. Everything is directly documented in the config.php file.

###Override Configuration In case you want to override the configuration but keep it easy to update PiTemp with a git pull, you can copy the config.php file and name it local.config.php. This file will then be ignored by git but merged with the config.php. This way you the config.php file stays untouched.

###Email Notification Since version 0.1.0 there's support for email notification. You can define a maximum temperature in the config.php (or local.config.php) file. If the temperature raises above this level, you receive an email notification to the configured address.

The configuration of email notification is not that hard once you've configured your Raspberry Pi to send emails. However, this can be a little bit tricky. Use one of the many tutorials out there in the world wide web. I used this one to set postfix up. You just have to make the PHP mail() function work.

###Pushover Notification Since version 0.2.0 there's support for Pushover notification. If you want to use this feature, make sure you have the cURL extension for PHP installed. You can do so by executing the following commands:

sudo apt-get install php5-curl

The next (and last) thing you have to do is insert your Pushover userkey in your config.php/local.config.php file.

###Pushbullet Notification Since version 0.3.0 there's support for Pushbullet. If you want to use this feature you just have to drop in your API Key and Device ID into the config/local.config.php file.

##Todo

  • Support F° & C° in notifications
  • Support multiple Raspberry Pi
  • Select timespan
  • Use Sqlite/Mysql database instead of textfile
  • Add possibility to test notifications
  • Add support for hostname/IPAddress in Pushover notification
