Swegon Ventilation Binding

This binding is used to get live data from Swegon ventilation systems into items in openHAB. It should be compatible with at least Swegon CASA models.

Prerequisites

swegongw is an application that reads packets from a serial port (an RS-485 adapter is needed) and relays them to openHAB via UDP. The Swegon Ventilation binding listens on the UDP port and extracts control data from UDP packets.

C code is available here.

Build:

gcc -std=gnu99 -o swegongw swegongw.c

Run:

swegongw -h 
swegongw -v -d /dev/ttyUSB0 -a 192.168.1.10

Binding Configuration

This binding can be configured in the file services/swegonventilation.cfg.

Property	Default	Required	Description
udpPort	9998	No	UDP port on which the binding will listen

Item Configuration

Format:

    swegonventilation="<data>"

Where <data> identifies a datum to retrieve:
