Application for the Web-IO Digital:

Monitor and control the Web-IO Digital directly from your browser

The browser is today the central display and operating tool in the PC world. A network and internet access is also virtually a standard today. Together with the Wiesemann & Theis Web-IO Digital boxes the browser can be used to remotely operate home and building technology.

Switching with the iPhone

Ad hoc access in the browser

All Web-IO models offer a simple Web page for an overview of the IO states.

web-io digital user

By going to http:<IP-Adresse>/user you can directly access the outputs and inputs.

The first time the user 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 user 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

The user page is based on JavaScript and AJAX technology 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.


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>/user
