FHT Binding

FHT is a range of devices produced by busware.de which allows to interact with various protocols and devices over radio frequencies. It's also possible to build one on your own.

Binding Configuration

This binding can be configured in the services/fht.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.

Item Configuration

Receive the valve position in percent. It can be bound to a Number item. Read-only.

{ fht="TR3D4900" }

Receive the window state of a FHT window contact. Read-only.

{ fht="TR952E90" }

This would be a binding to receive reports of a FHT80b. Currently only the measured temperature is received.

{ fht="TR3D49" }

This binding enables you to send commands to a FHT80b. Currently this will be mostly the desired temperature. But you need also a writeable binding to update the time on your FHT80b.

{ fht="TW3D49" }
