Swegon Ventilation Binding

Vlad Ivanov edited this page Jun 21, 2015 · 2 revisions

Introduction

Swegon ventilation binding is used to get live data from Swegon ventilation systems. Binding should be compatible with at least Swegon CASA models.

Swegon gateway

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

C code is available here

Build command:

gcc -std=gnu99 -o swegongw swegongw.c

Execution:

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

swegongw help is available by executing the following command:

swegongw -h 

For the installation of the binding, please see Wiki page Bindings.

Binding Configuration

openhab.cfg file (in ${openhab_home}/configurations folder).

######################## Swegon ventilation Binding ###################################
#
# UDP port (optional, defaults to 9998)
# swegonventilation:udpPort =9998

The swegonventilation:udpPort value specifies UDP port on which the binding will listen. Configuration is optional, by default binding listens on UDP port 9998.

Item Binding Configuration

In order to bind an item to the device, you need to provide configuration settings. The easiest way to do so is to add some binding information in your item file (in the folder configurations/items). Example of the item binding:

swegonventilation="<data>"

Where <data> identifies a data item. See a complete list below.
