# Swegon Ventilation Binding v1

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.

# Item Configuration

Format:

    swegonventilation="<data>"

Where <data> identifies a datum to retrieve:

# Examples

Number	OutdoorTemperature	{ swegonventilation="OutdoorTemperature" }
Number	SupplyAirFanSpeed	{ swegonventilation="SupplyAirFanSpeed" }
Switch	Preheat	            { swegonventilation="PreheatState" }
