BACnet Gateway for weather information


The eBACgw-Meteo is a BACnet gateway to the weather report services that collect data in different specified locations. These services are free and accessible through the Internet.

Functionality

  • automatic service subscription
  • measurement of 9 meteorological quantities
  • observation of 7 atmospheric phenomena
  • updating interval user selectable
  • alarm and event notification
  • BBMD support
  • WEB configurator

Application

The eBACgw-Meteo gateway is suited for building automation plants where is needed to integrate the weather information collected in a specific location into the BACnet network. Gateway data are updated time after time when a new weather report comes out, usually every 30-60 minutes. Device set-up is very simple: it’s sufficient to set the measurement geographical location (according to ICAO standard) and select the service sampling time. Service access is possible through HTTP inquiries and usually doesn’t need special settings in corporate router/firewall.
Alarm and notification events can be set-up on the basis of user defined limits or change of state of every managed object. In the “description” field of every object there is the time of the weather report containing the current data.
