99% of this work was borrowed from http://my.homedash.org/ . The difference is, I didn't want to rely on jstorage for the parameters and wanted to store these files directly on my SSP-3's (and to make the instructions Dad-proof).

Edit src/index.html and substitute the variables MY-IP-1 and DEVICENAME-1 with your correct settings. Repeat for every device in your location. Don't forget to increment the switch-N value in the id attribute of the li tag.

For example:

<ul id="switches">
  <li id="switch-1" data-ip="192.168.15.230"><span title="192.168.15.230"><i class="fa fa-power-off"></i>Bookshelf Lights</span></li>
  <li id="switch-2" data-ip="192.168.15.231"><span title="192.168.15.231"><i class="fa fa-power-off"></i>Diningroom</span></li>
  <li id="switch-3" data-ip="192.168.15.232"><span title="192.168.15.232"><i class="fa fa-power-off"></i>Kitchen Widget</span></li>
  <li id="switch-4" data-ip="192.168.15.233"><span title="192.168.15.233"><i class="fa fa-power-off"></i>Livingroom Lamp</span></li>
</ul>

scp the contents of src/ to your device (default password is p9z34c):

scp -rp src/* root@MY-IP-1:/www/

Repeat this step as many times as you have devices.

Open your browser and type in: http://MY-IP-1. The web page's JavaScript will ping /cgi-bin/json.cgi script on every device for status, so it is mandatory to copy at least src/www/cgi-bin/json.cgi to every device (destination path: /www/cgi-bin/json.cgi).

Open the URL on your mobile device (e.g. Safari), click on the Share button, then tap the Add to Home Screen icon. Profit.
