Weather Display Live Clone for PiFace Control and Display (pifacecad). Written in Python.

pifacecad-wdlive is a simple weather display console.

pifacecad-wdlive can be configured on the command line to read and display data from any WD Live clientraw.txt file available on the web via http. It polls the specified file once a minute updating the pifacecad's display with the new data.

pifacecad-wdlive supports the display of many different weather items and measurement units.

It can optionally work with an IR remote control via LIRC.
