FS20 Binding

This binding enables support of sending and receiving FS20 messages via the CUL transport. You will need CULLite or similiar device from busware.de. This device needs to be flashed with the latest culfw firmware from culfw.de.

Binding Configuration

This binding can be configured in the services/fs20.cfg file.

Property Default Required Description
device   Yes in the form serial:<device>, where <device> is a local serial port, or
network:<host>:<port>, where <host> is the host name or IP address and <port> is the port number. The network option works with ser2net from a tuxnet device
baudrate   No one of 75, 110, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
parity   No one of EVEN, ODD, MARK, NONE, SPACE

When using a serial port, you may need to add -Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0 in your server startup. Please consult the forum for the latest information.

To use a networked CUL device for FS20 from ser2net, this line in /etc/ser2net.conf on the remote <host> will publish the serial interface (replace /dev/ttySP1 with whatever is appropriate):

3333:raw:0:/dev/ttySP1:38400 8DATABITS NONE 1STOPBIT

From the above, your device property would be network:<host>:3333.

Item Configuration

You can use Switch items and Dimmer items with this binding. You need to know the house address and device address of the device you want to receive messages or send messages to. To find these addresses you can start openHAB in debug mode. The CUL transport will print all out all received messages.

A sample switch configuration looks like this

Switch  WallSwitch1 "Wandschalter 1"  { fs20="C04B00" }

where C04B is the house address and 00 the device address. If you want to control switches or dimmers you can simply create you own house and device address. You can set such devices in a pairing mode and they will react to the first message they receive.

Coming from FHEM?

In the fhem.cfg you find such statements:

define AmbiLight FS20 c04b 01

Just write the last “words” together and you have the full address you need for your item (see above).
