Conventional timers make it possible to change daily to specify repeating switching times. In some cases, certain days of the week are also specified. The switching times but are always static and changes require on-site access on the device.

Unlike ordinary timers, the switching times of the Web-IO Time Switch in electronic calendars similar to a Appointment management recorded. For each switching output, an independent calendar. The corresponding output switches with start of an entered appointment and at the end of the appointment again again.

In the simplest case, the Web-IO Time Switch can be configured as follows: that it automates the calendar files cyclically in an online calendar without the need for user intervention on the Web-IO.

The advantage of this technique is that changes in switching times conveniently and from anywhere – in the browser or directly on the mobile phone And that is what we are talking about.

Flexible design of switching times

Most online calendars keep the appointments in the standardized iCal format (*.ics). This ports almost all possibilities of the iCal appointment management on the management of the switching times of the Web-IO Time Switch. These include, but are not limited to:

• Automatic consideration of summer and winter time
• Setting up recurring appointments or recurring switching times, for example:
  • daily at the same time
  • only on certain days of the week
  • weekdays only
  • only on weekends
• Determine exceptions for recurring appointments, for example:
  • for holidays
  • special events
  • Holiday regulations
  • …
• Set an end date for recurring appointments (last run)

In addition, it can be determined in which cycle the switching times of the Web-IO with the online calendar.

If there is no online access, the Web-IO Time Switch switches to the – a permanent Internet access is therefore not necessary.

Manually upload calendar files

Another possibility to set the switching times for an output, consists of loading iCal files from the local hard disk into the Web-IO Time Switch.
