Controlling the home from distance is made via a web access.
In this example, the server is harmonia.local
: evidently, this has to be replaced by your local server name.
Contents
Install a web server
Install the web server:
su apt-get update apt-get install lighttpd apt-get install php5-cgi lighttpd-enable-mod fastcgi fastcgi-php service lighttpd reload service lighttpd status
Configure the base directory and modify the line with server.document-root
:
WWW_ROOT=/mnt/storage/www/ nano /etc/lighttpd/lighttpd.conf service lighttpd reload cp /var/www/index.lighttpd.html $WWW_ROOT
Navigate to your server within a web browser. You should discover the default lighttpd placeholder page.
Install the webSocket libraries
jQuery
Download the latest compressed, production jQuery version.
wget http://code.jquery.com/jquery-2.1.4.min.js
XML::Simple
Check if the XML::Simple
is already installed:
perl -MFile::Find=find -MFile::Spec::Functions -Tlw -e 'find { wanted => sub { print canonpath $_ if /\.pm\z/ }, no_chdir => 1 }, @INC' 2> /dev/null | grep -i 'XML/Simple.pm'
Install the library:
perl -MCPAN -e "install 'XML::Simple'"
Alternatively, on Ubuntu:
apt-get install libxml-simple-perl
Net::WebSocket::Server
Check if the XML::Simple
is already installed:
perl -MFile::Find=find -MFile::Spec::Functions -Tlw -e 'find { wanted => sub { print canonpath $_ if /\.pm\z/ }, no_chdir => 1 }, @INC' 2> /dev/null | grep -i 'WebSocket/Server.pm'
Install the library:
perl -MCPAN -e "install 'Net::WebSocket::Server'"
Prepare a home control page
Create the home control directory:
WWW_CONTROL=$WWW_ROOT/homeControl mkdir -p $WWW_CONTROL chmod -R 775 $WWW_CONTROL chown -R control:users $WWW_CONTROL cd $WWW_CONTROL
In this directory, create a simple.html
control page:
<html> <head> <script src="//code.jquery.com/jquery-1.11.0.min.js"> </script> </head> <body> <!-- Light controls .................................................... --> <br /> <table align="center" border='0px' cellpadding='12px' cellspacing='0px' bgcolor="#CCCCCC"> <tr> <th width="240px">ceiling</th> <th width="240px">stand</th> </tr> <tr> <td align="center"><input id="ceiling" type="checkbox" /></td> <td align="center"><input id="stand" type="checkbox" /></td> </tr> </table> <!-- Websocket java script ............................................. --> <script> $().ready(function() { var ws = new WebSocket('ws://harmonia.local:8080/'); ws.onopen = function() { console.log("Web socket started"); } // outgoing messages $('#ceiling').on('change', function() { ws.send('ceiling ' + $(this).is(':checked')); }); $('#stand').on('change', function() { ws.send('stand ' + $(this).is(':checked')); }); // polling message window.setInterval( function() { ws.send('poll request'); } , 100 ); // incoming messages ws.onmessage = function(message) { console.log(message.data); var words = message.data.split(' '); if (words[0] === 'ceiling') { $('#ceiling').prop('checked', words[1] == 'true'); } if (words[0] === 'stand') { $('#stand').prop('checked', words[1] == 'true'); } } }); </script> </body> </html>
Navigate to the control page: http://harmonia.local/homeControl/simple.html
