Smart Home - Integrating weather data


Controlling building functions with LOGO! 8 depending on the weather.

The functions of your building (light, shutters, and heating) are to be influenced based on the current weather. In this application example, a LOGO! 8 station with weather sensors (wind, rain, temperature, and sunshine) and a Touch Panel is to be connected to an existing home automation solution. Depending on the weather data, various home functions are controlled automatically and weather warnings are being generated. This application example is an expansion of existing application examples (links at the end of this document). 

Efficient, flexible and time-saving

Your benefits when you use this application example.

Save energy through weather-dependent lighting, shading, and ventilation.

Possible uses

You can use this application example for all aspects of building automation.

Some examples for the possible uses:

  • Public buildings
  • Private and vacation homes
  • Hotels and hospitality industry
  • Sports arenas
  • Commercial buildings

How does it work?

You expand your existing building automation to include the latest weather data with an additional LOGO! station. The weather data is transmitted to your home controller via Ethernet and can also be displayed on an HMI device. The weather data for temperature, rain, light, and twilight is collected as analog values (0-10 V DC). The wind speed by means of a pulse counter.
