Controlling the Web-IO Digital with a mobile phone

Entry to the Smart Home, using the iPhone for remote control

Mobile phones are carried by nearly everyone today. In addition to the original idea of being able to phone from everywhere, cell phones are increasingly providing a means of connecting to the Internet. The iPhone in particular has acquired almost cult status. Together with the Wieseman & Theis Web-IO Digital boxes, internet-capable cell phones like the iPhone can be used as remote control for home and building technology.

Ad hoc access on the smart phone


All Web-IO models offer smart phone users a web page customized for the phone display size.

By going to http:<IP-Address/smart you can directly access the outputs and inputs.

The first time the smart page is opened it requires a password. The password can be stored on the smart phone so that the login procedure can be skipped.

The smart page offers the following functions:

  • Dynamic display of the inputs
  • Dynamic display of the outputs
  • Operation and display of the outputs
  • IO names configured in the Web-IO are copied over
  • Password protected access
  • No apps required

The smart page is based on JavaScript and AJAX and continually communicates with the Web-IO. When a change is detected on the inputs, outputs or counters, the web page is automatically updated. Of course you can always make minor changes to our pre-prepared web pages to meet your own needs.

A detailed manual for creating iPhone-optimized Web pages can be found here:

The solution shown is based on general Web standards and has the advantage that you don’t need to purchase any apps or IPA downloads from the App Store.

Communications channels

Mobile phones like the iPhone can open the connection to the Internet either over the public cell phone network (UMTS/GPRS) or via a WLAN connection or hotspot. Both the access speed and any fees vary considerably.

If you want the Web page to be opened on the iPhone for a longer period of time, bear in mind any resulting fees for accessing the cell network.

If there is WLAN access, the example shown functions on all iPod Touch models!


These steps are necessary in order to be able to remotely control the existing network:

Once these steps are completed the Web page can be displayed in the iPhone.

The page is opened as follows: http://<ip-adresse>/smart
