py-webrelais

What it does

py-webrelais offers a REST-API to control the [1] K8IO Relais-Card from Pollin, connected to the parallel port. Its developed explicitly for Linux, but should run on Windows, too (not tested)

Basic Usage

• GET / Shows a page to control the relais card

• POST /ports/[0-7]? Set a relais

• GET /ports/[0-7]? Get the state of a specific relais

• DELETE /ports/[0-7]? Set relais to off

If no number is given, it will return/set/reset all relais

Dependencies

• flask
• pyparallel

Installation

sudo apt-get install python-parallel python-flask

You need to do this to get the parallel library to work:

sudo rmmod lp
sudo modprobe ppdev

Add your user to the lp group or change the permissions on /dev/parport0

Now everything should work fine
