eziopi is a set of scripts for webiopi which allows to create new applications easily.

• unique JSON configuration file
• integrated program scheduler: APScheduler
• multiple program types (cron-style, sensor's min/max, sunrise/sunset, custom)
• sensor monitoring (with RRDtool and javascriptRRD)
• unified interface

A script manage sensor monitoring and logging (status.py), while another manage the programs scheduling (command.py). A configuration file (cfg/cfg.json) defines sensors, graphs and applications. A status page shows all monitored data, and each application page generate buttons to program a GPIO's activation based on a common JS script (eziopi.js).

• webiopi

• APScheduler

  cd ~/eziopi/python
  tar -xvzf APScheduler-3.0.0.tar.gz
  cd APScheduler-3.0.0/
  sudo python3 setup.py install
  

• rrdtool

  • rrdtool dependencies:

    sudo apt-get install rrdtool libcairo2-dev libpango1.0-dev libglib2.0-dev libxml2-dev librrd-dev
    

  cd ~/eziopi/python
  tar -xvzf python-rrdtool-1.4.7.tar.gz
  cd python-rrdtool-1.4.7/
  sudo python3 setup.py install
  

• ephem

  cd ~/eziopi/python
  tar -xvzf ephem-3.7.5.1.tar.gz
  cd ephem-3.7.5.1/
  sudo python3 setup.py install
  

• additionnal python modules

  sudo apt-get install python3-requests python3-sqlalchemy
  

• webiopi config file

  cd ~/eziopi/
  sudo cp cfg/webiopi_config /etc/webiopi/config
  

• configuration file

  a JSON file including following parts:

  • location

    used to get weather conditions or compile sunrise/sunset times

  • graphs

    define graphs data sources and parameters

  • sensors

    list sensors type and id

  • app

    define applications program type and GPIO

  example: see cfg/cfg.json, creates a simple application to control 2 lights and monitor in & out temperature

• create new app folder

  for each app created webiopi needs a new folder (with eziopi it's simply a symbolic link to the default app)

  cd ~/eziopi/html/app/
  ln -s default-app/ NEW_APP_NAME
  

• generate RRD graphs

  a script generates graphs from configuration file

  cd ~/eziopi/utils/
  ./rrdcreate.py -d ../html/app/status/
