WR3223 ventilation controller Binding

The WR3223 ventilation controller is used for room ventilation systems, for example in houses produced by company “Schwörer Haus”. The manufacturer of the controller is Hermes Electronic.

The WR3223 binding can read several measurements and the current state of the ventilation system. It can also adjust the fan speed, operation mode and the target temperature.

Prerequisites

The WR3223 can be connected by an RS232 or USB adapter. The adapter can be orderd from Hermes Electronic. If you want to connect the WR3223 by yourself, have a look at: https://community.openhab.org/t/wr3223-ventilation-controller-schworer-haus/

To control the WR3223, you have to disconnect the control panel, otherwise the WR3223 will ignore the command from the serial port.

Binding Configuration

This binding can be configured in the file services/wr3223.cfg.

The connection must be configured via either the serialPort setting or via the host and port settings.

Property	Default	Required	Description
serialPort		Yes (if serial port is used)	Serial port where the WR3223 is connected. E.g. /dev/ttyUSB0
host		Yes (if TCP is used)	IP address of the TCP to serial gateway
port		Yes (if TCP is used)	port number of the TCP to serial gateway
refresh	15000	No	Refresh interval in milliseconds. The WR3223 needs a refresh at least every 20 seconds!
controllerAddr	1	No	The controller address is normally 1.

Item Configuration

The syntax of the binding configuration strings accepted is the following:

wr3223="<device-command>"

where <device-command> is replaced with the WR3223 command from the list below:
