Quick Reference for WebIOPi

This is taken from Eric Trouch's page at http://webiopi.trouch.com/INSTALL.html

Installation

WebIOPi is developed and tested on Raspbian. You only need Python, either 2.7 or 3.2. Download, then extract and install WebIOPi. The setup script will automatically download and install required dependencies using apt-get. You may have to manually install GCC and Python development headers if you are not using Raspbian.

Upgrade note: Stop your existing WebIOPi service, then process with the setup. Your configuration will be kept but others files will be override.

See downloads page to get latest package, and adapt x.y.z with the version you download.

$ tar xvzf WebIOPi-x.y.z.tar.gz
$ cd WebIOPi-x.y.z
$ sudo ./setup.sh

Setup may take a moment.

Running WebIOPi

Finally, use webiopi command :

$ sudo webiopi [-h] [-c config] [-l log] [-s script] [-d] [port]

    Options:
      -h, --help           Display this help
      -c, --config  file   Load config from file
      -l, --log     file   Log to file
      -s, --script  file   Load script from file
      -d, --debug          Enable DEBUG

    Arguments:
      port                 Port to bind the HTTP Server

For instance, to start with verbose output and the default config file :

$ sudo webiopi -d -c /etc/webiopi/config

You’re done, and ready to enjoy WebIOPi ! But the server and GPIO state will be lost when you’ll stop the script (CTRL-C) or close the terminal.

Running WebIOPi (Daemon)

You can also start/stop the background service, the configuration will be loaded from /etc/webiopi/config.

$ sudo /etc/init.d/webiopi start
$ sudo /etc/init.d/webiopi stop

Auto start at boot

To setup your system to start webiopi at boot :

$ sudo update-rc.d webiopi defaults

To remove webiopi start from boot :

$ sudo update-rc.d webiopi remove

Access WebIOPi over local network

If your Raspberry Pi is connected to your network, you can open a browser to http://raspberrypi:8000/ with any device of your network. Replace raspberrypi by its IP.

Default user is “webiopi” and password is “raspberry”

By choosing the GPIO Header link on the main page, you will be able to control GPIO using a web UI which looks like the board header.

  • Click/Tap the OUT/IN button to change GPIO direction.
  • Click/Tap pins to change the GPIO output state.
